Industrial Dehumidifier Capacity Selection

indistry dehumidifier capacity selection

Industrial Dehumidifier Capacity Selection is a method of selecting a specific dehumidifier model depending on the calculation of humidity removal per day in a given location.

The industrial dehumidifier selection is done by performing a calculation for the humidity removal.

For this purpose, we have to collect data such us the temperature, current humidity, target humidity and the size of the place. With this data and calculation we can choose a dehumidifier model apt for the desired space.

The industrial dehumidifier capacity selection is essential as it allows you to pick the right model of the dehumidifier. This is especially very important for the industrial series as these machines are high capacity units.

We use industrial dehumidifiers to eliminate moisture from large rooms and spaces.

This helps in repairing water damage as it removes the moisture from large spaces and avoids the molds from growing. Dehumidifiers play a very important role in the commercial and industrial sectors involving storage of materials which might be very sensitive to moisture. These units are also used to maintain clean air which in turn will maintain a healthy atmosphere. Also, there are many allergies which can be avoided due to dehumidifiers. commercial-dehumidifier-modelDH600BY

Industrial dehumidifiers are designed for larger areas to maintain a moisture free atmosphere. As these machines need to remove a high capacity of moisture, they need to be featured for high capacity performance.

Each dehumidifier has a capacity of humidity removal at a particular level of temperature and humidity. The industrial dehumidifier capacity is calculated on the basis of the following parameters:

  1. Dimensions of the room (Length x Width x Height).
  2. Temperature maintained in the room.
  3. Current Humidity in the room.
  4. Humidity level to be achieved in the room.

These parameters are different for each scenario, hence the industrial dehumidifier capacity selection for each space is different.

Dehumidifiers can be divided into two types namely:

    • Condensation Type:

When we consider the temperature of the room to becondensation-type-industrial-dehumidifier 15°C and above (normally up to 40°C),we would suggest the condensation type units.
These units convert the moisture in the room into water and finally drain the same out of the machine. Capacity calculation for the same needs to be done with the above-mentioned parameters.

    • Desiccant Type:

When we consider lower temperature ranges, for example below 10°C (normally up to -20°C), we would need a desiccant type dehumidifier to remove humidity. These industrial units would convert the moisture in the room into wet air and dehumidify the space. VackerGlobal supplies Portable Industrial Dehumidifier The capacity calculation for the same needs to be done with the above-mentioned parameters.

Controls and Design

These industrial units are huge capacity machines, very powerful as they intend to control humidity for large areas and spaces. The exterior parts of these machines are rugged and in turn, protect the internal parts from the outside environment. Commonly industrial condensation dehumidifiers have inbuilt tanks to drain out the collected humidity which is in the form of water. Depending on the capacity of the dehumidifier, there is an inbuilt tank of a specific capacity for each machine.

Also, there is an option where a pipe can be connected directly to the drainage and the water can be automatically discarded.

There is wall mounted as well as floor mounted dehumidifiers in the industrial series.

Generally, the industrial dehumidifier capacity selection starts with a minimum capacity of around 50 liters per day to approximately 1,040 liters per day or more. This again depends on the current temperature and humidity in the location, the target humidity which needs to be achieved for the location and most importantly the dimensions of the place.

For a better understanding, please find an example of how an industrial dehumidifier capacity selection is done. The calculation for the same is given below:

  1. The dimension of the space is Length (8m) x Width (5m) x Height (3m).
  2. The Temperature in the area is 20°C.
  3. Current Humidity in the area is 80%.
  4. Target humidity to be achieved in the area is 50%.
  5. The capacity of humidity removal is 14.9304 liters per day.

Reasons for failure of mapping study of a cold room

mapping study of a cold room

Mapping study is the procedure or process of recording and mapping the temperature and humidity in various assets such as Warehouse, cold room, vehicle, Freezer etc. The temperature and humidity will not be same everywhere in the asset. There will be a different temperature and humidity in the corners and different in the center of the space being unused.

In a cold room, the area which is near to a cooling fan will be having coldest temperature and near to the door may have the hottest temperature.

The Basis of temperature & Humidity mapping of the various assets is to assure that all storage areas should maintain the required temperature and humidity. The result of the mapping study is a temperature distribution map defining the cold spot and hot spot of the storage area.

Mapping study will be carried out with a sufficient number of Data Loggers. We distribute these data loggers within the 3-dimensional space or the storage area of the asset to map temperature and humidity. We place these loggers in a horizontally, vertically and depth plain. We locate the data loggers in locations that are likely to have temperature variations or humidity variations. temperature-mapping-study-procedure-flow-chart

The temperature mapping study includes four stages:

  1. Preparing the SOP, protocol or procedure for temperature mapping study.
  2. Carrying out different tests of  mapping study as per the protocol.
  3. Preparing the Report for mapping study after data collection.
  4. Giving the recommendation for remedial actions after analyzing the mapping report.

The mapping study in the cold room includes various different tests.

The test will be carried out in Empty and Loaded conditions. There will be a power failure test and a door opening test followed by Temperature Recovery Test in both empty and loaded conditions. As per the dimension & layout diagram of the cold room, we place the data loggers. One data logger will be outside of the cold room for recording the ambient temperature and humidity.

There will be acceptance criterion for the mapping study. All the data Loggers located inside the cold room should maintain the temperature between the defined low limit and high limit. Depending upon the type of asset, the lower limit, and the higher limit will be changed. For a cold room, usually the low limit is 2°C and high limit is 8°C. There will be a specific limit for humidity also such as between 45% to 65%. After the execution of different tests, there is a chance of failure in the mapping study in a cold room.

Hot cold points cold room

Hot & cold points inside cold room

The reason for the failure of the cold room in a recent case study was due to Low temperature at a certain point and high temperature at certain other areas. During the period of mapping study, when the temperature goes above the high limit or below the lower limit, it will lead to failure in the mapping study.

In such case, the customer has to take corrective actions to close the deviations. Reasons for failure of Humidity distribution study in another case study was very high humidity in the cold room.

Common reasons for failure of a cold room

We are listing below common reasons which cause failure of mapping study fo a cold room.

  1. Air curtains may be required at the doors of the cold room to maintain the temperature and humidity inside the cold room.
  2. The temperature displayed in the temperature controller, which is kept outside the cold room may not be correct.
  3. The temperature controller and corresponding sensors are not properly calibrated. You will be setting a certain temperature on the controller. However since the controller is not properly calibrated, it will be sending wrong signals to the cooling units.
  4. The location of the sensor of the cooling unit may not be at a correct location.
  5. The humidity may be higher than permitted levels.
  6. The uniform distribution of temperature will be affected if the location of the cooling units is not positioned correctly.
  7. The defrost cycle of the cooling units may not be correctly timed. If there are more than one cooling unit, the defrost cycle has to be properly adjusted so that both the units do not go off together.
  8. High racks in front of the cooling units may block proper airflow inside the room.

Recommendations for corrective actions against failure of mapping study

The mapping study report will include the remedies or recommendations for the failure of the mapping study. They include:

  1. Calibration and checking of the controller of the cooling unit.
  2. Adjust the high and low cut-off limits of the controller. eg. for a cold room you may program the upper and lower limits as 6°C and 4°C respectively. This will help you to achieve a constant temperature between 2° C to 8°C.
  3. If corrective actions are not effective, the customer has to isolate the hot or cold areas. They should not store products in these areas.
  4. Installing a continuous temperature monitoring system inside the cold room for real time monitoring.
  5. The work practices such as keeping the door opened or closed need to change.
  6. The racking or shelving needs to be repositioned to improve air circulation.
  7. Relocating the heating devices if applicable.
  8. Adding cooling units if required.
  9. Installing a humidifier or dehumidifier in the cold room to maintain the desired humidity.

Where to place a temperature & humidity sensor in a cold room,warehouse,van or refrigerator?

location to place temperature humidity sensor

This article is particularly about cold rooms and walk-in freezers for storage of medicines and vaccines. We are explaining on deciding the number of sensors and location of sensors of a temperature monitoring and alert system. The operator or owner of the cold room has to continuously monitor and record the temperature. Sometimes it may be essential to record humidity also. The question is where to place the sensors in the cold room continuous monitoring system. These are the sensors which generate alarms in case the temperature or humidity goes above the permitted limits.

How to decide the number and locations of sensors of temperature alert system?

First of all, we have to carry out a temperature mapping study to decide the hot and cold points. Based on these, we can decide the number and location of sensors. We can see that in many cold rooms, the operator places sensors of a monitoring system without a mapping study. The sensor will be located at his most convenient location. Sometimes this may be close to the door, which is irrational. If an auditor asks a question as to how the location was decided, there won’t be any answer.

Hot cold points cold room

Hot cold points cold room

We will explain how to decide the same.

After conducting a mapping study, we can identify the hot and cold points of the cold room. As an example, we will consider a small sized cold room. We assume that we use 10 data loggers to conduct the mapping study. After analyzing the complete data of a loaded test, we can find out the hottest and the coldest points. We should not consider data of the empty test, door opening test and power failure test for this purpose. The air circulation and stabilization of the cold room will be tested in a loaded test.

The hottest point and coldest point will be normally in different places. We have to place one temperature sensor at the hottest point and one sensor at the coldest point. Please see the following examples for further clarification. In both the examples we are assuming cold storage of 2 to 8°C for storage of medicines. It is assumed that we used 10 data loggers for the mapping study. DL1 is data logger1, DL2 is data logger 2 and so on.

Example 1 for cold room temperature monitoring & alert system

In this example we will consider the following maximum and minimum values of the data loggers:

  1. DL1 : 7.2°C, 3.1°C
  2. DL2 : 7.1°C, 3.3°C
  3. DL3: 7.0°C, 3.1°C
  4. DL4:7.1°C, 3.4°C
  5. DL5:6.9°C, 3.3°C
  6. DL6:7.1°C, 2.6°C
  7. DL7:7.2°C, 3.3°C
  8. DL8:7.7°C, 2.7°C
  9. DL9: 7.1°C, 3.1°C
  10. DL10:7.3°C, 3.5°C

In this case, you can see that location of DL 6 is the cold point. Similarly, the location of DL8 is the hottest point. These are the weakest points in the cold room. Now you have to place one data logger at the location of DL6 and one data logger at the location of DL8.

Example 2 for cold room temperature monitoring

In this example we will consider the following maximum and minimum values of the data loggers:

  1. DL1: 7.2°C, 3.1°C
  2. DL2: 7.1°C, 3.3°C
  3. DL3: 7.0°C, 2.6°C
  4. DL4:7.1°C, 3.4°C
  5. DL5:6.9°C, 3.3°C
  6. DL6:7.1°C, 2.6°C
  7. DL7:7.2°C, 3.3°C
  8. DL8:7.7°C, 2.7°C
  9. DL9: 7.1°C, 3.1°C
  10. DL10:7.3°C, 3.5°C

In this case, you can see that locations of DL 6 & DL3 are the cold points. There are two cold points. However, there is only one hot point which is DL8. These are the weakest points in the cold room. In this case, you have to place one data logger each at the locations of DL3, DL6 and DL8.

Data logger location for humidity monitoring of cold room (humidity sensor)

For humidity, there are no hot and cold points. Generally, the humidity quickly equalizes across the entire cold room, once we close the room. Hence, you can consider the following general rules:

  1. Hot and Cold spots of a Cold room temperature distribution

    Cold room temperature distribution

    We should not place the Temperature & humidity data logger near to the door. The humidity near the door increases as soon as the door is opened.

  2. The humidity data logger should not be directly in front of the airflow of the chiller unit.
  3. If you have one of the temperature data loggers deep inside the cold room, it is better to place the humidity sensor of the data logger near to this sensor. You will be able to correlate humidity variation with respect to temperature variations.
  4. For a small to medium-sized room, only one humidity sensor is sufficient irrespective of the number of temperature sensors.
  5. If you have a dehumidifier inside the room, you should place the humidity sensor far away from the outlet of the dehumidifier. The humidity at the inlet of the dehumidifier will be always high and at the outlet will be very low. Placing a humidity data logger near to the dehumidifier will generate readings which are not in line with the distributed humidity,

However, if humidity is a very critical parameter for your stored goods, you may have to consider more humidity data loggers for the continuous monitoring system.

How to decide the location of temperature sensors in Reefers or Vans?data-logger-locations-inside-reefer-truck

In principle, the methodology is the same as above. You should take data of temperature mapping study during a loaded test excluding data of power failure test, door opening test etc. You have to decide at least one each of hot point and cold point and place sensors accordingly.

The main limitation is that you can place a sensor only on the wall. So even if you find a hot point somewhere in the middle of the van, you cannot place a sensor there. This is because inside a van you always have a different pattern of loading. Hence you can install the sensor for continuous monitoring somewhere on the nearby wall or ceiling.

The logic for selection of the sensors point is to closely monitor the variations. You should receive an alert as soon as the temperature goes above or below the limits. You have to select the location and number of sensors accordingly. In case the cooing unit is not working, the hottest point will be the first one to cross the upper limit. Hence you will receive an alert as soon as the hottest point crosses the limit. Same is the case for the cold spot.

FAQ on a temperature monitoring system for medicines and vaccines

  1. What are the regulatory requirements for the selection of a temperature recording system in pharma & food segments? If you are in the USA, you should have systems complying with 21CFR Part 11 standards. Many other countries follow this or other standards. There is no common standard across the world. World Health Organization (WHO) also has a standard specification for Distribution of Pharma products.
  2. What are the minimum ideal technical requirements for a temperature monitoring system for pharma and food segments? (1) It should be able to generate a phone, SMS or local siren alerts (2) The system should ideally work even in case of a power failure (3) The system should ideally work even in case of a WiFi or network failure (4) It should be possible to calibrate sensors individually (5) There should not be any loss of existing data in case of a power or network failure (6) You should be able to program the sampling interval based on the critical nature of the goods. (7) you should preferably able to use a single system for the warehouse, cold room, refrigerator, trucks etc. This makes your life easy. (8) It is best to use sensors with inbuilt battery without the need for external power supply. This is extremely essential for warehouses. Pulling the power supply to the sensors to various sensors will be challenging. Also during operations, damages may occur to these power cables.
  3. Is it possible to use a single temperature recording system for warehouse, cold room, trucks etc? Yes, there are such systems available. We highly recommend using such systems. Thus you will be able to use Big Data Analytics to improve the efficiency of operations.
  4. What kind of power supply is ideal for temperature monitoring and alert systems? It is ideal to use systems with internal battery back up. In this case, you will receive a phone call or SMS alerts even in case of power supply.
  5. What kind of an alert system is ideal for a temperature alert system? A phone call alert system using a SIM card with battery back up is most ideal. In such a case you will receive phone calls without power supply and network connection. This may be the most dependable alert if you have costly assets. The system should be able to make phone call alerts to multiple operators.

We provide all kind of temperature mapping study, temperature qualification study, temperature monitoring systems and temperature alert systems across the world.

Why to use automated air curtains for pharmaceutical storage

air curtains for pharmaceutical storage

For pharmaceutical storage areas, maintaining proper temperature and humidity is always a challenge. The warehouses need to be maintained under a temperature condition of 15-25°C and 65% Relative Humidity. For cold rooms, the temperature has to be maintained between 2-8°C and 65% Relative humidity.industrial-air-curtain

As the ambient conditions are hot and humid especially in summer, it is a huge challenge. A Certain level of control can be achieved by installing air curtains.

Why use Air curtains for warehouse and cold rooms?

The industrial air curtain is an electric fan fitted inside a straight duct shaped enclosure. This is mounted above the door of the warehouse or cold room similar to a curtain. When switched on, this will generate continuous air forming a virtual curtain. To a certain extent, this will prevent external air from coming into the warehouse. This will protect both temperature and humidity from entering the warehouse or cold room.warehouse-air-curtain

Generally, people operate this manually, which means they switch on and off using an electric switch mounted somewhere near the door. When the door is opened, the operator will switch ON the fan. Once the door is closed, the air curtain also has to be switched OFF.

As you can imagine this is not efficient and if the operator forgets to switch ON, the whole purpose is lost.

Advantages of automatic  Switch ON/OFF air curtain

In order to prevent operator negligence, it is better to automate the industrial air curtain. Many of the pharmaceutical industries now insist that the same has to be automated. In this system, as soon as the door is opened, the fan works automatically. Similarly, as soon as the door closes, the fan stops automatically. This automatic switch ON and OFF system is now preferred by many pharmaceutical and food industries.

This automation can be carried out at a very low cost and can work very efficiently.

This is carried out by connecting an infrared sensor or electrical sensor on the door. As soon as the door is opened, the sensor detects and sends an ON signal to the fan. Instead of a sensor, a signal can be generated from the control panel of the door opening switch also.

What is difference between Air curtain and PVC curtain/Strip curtainpvc-strip-curtains

The PVC curtain is a curtain made of transparent PVC strips. An Air curtain is an electric fan. We definitely install recommend to use PVC curtains in addition to an air curtain. This will add much more protection from the external air.

An air curtain and strip curtain will definitely improve the performance which can be validated by conducting a temperature mapping study. Visit Vackerglobal to learn about more related services.

Temperature Monitoring of Cooler Box

temperature monitoring of cooler box

Maintenance of temperature inside a cooler box is a very important factor for the working of the device. Vacker UAE has been providing different types of Temperature Data Loggers for their clients and temperature data logger for monitoring the temperature in cooler boxes is one of them. Vacker UAE provides their services in different regions of UAE especially in the cities such as Abu Dhabi, Ajman, Dubai, Fujairah, Sharjah, Umm al-Quwain, etc.

Temperature Monitoring of Cooler Box

Temperature Monitoring of Cooler Box

The cooler box in medical fields is generally used to store and transport different types of vaccines and medicines. Vaccines are very sensitive to temperature and slight change in them can degrade the quality and effectiveness of the vaccines. The World Health Organization(WHO) has described certain parameters of temperature for the storage and transportation of vaccines. According to the parameters, the safe temperature for vaccines to be stored and transported should range from 2 degree Celsius to 8 degree Celsius.

If the temperature is higher than the recommended temperature, then the potency of the vaccines decline very fast. Whereas, if the temperature is lower than the recommendation, reactogenicity of the vaccines increases and potency of the vaccine decreases. Hence, it is very important to monitor the temperature of the cooler box constantly.

Why use Temperature Data Logger by Vacker UAE for Temperature Monitoring of Cooler Box?

Lack of monitoring of temperature of the cooler accurately can mislead a health professional and its recipients about the effectiveness of the vaccine. The faults in the cooler box may also remain undetected if the temperature is not monitored properly.

The WHO recommends monitoring the cooler box of vaccines continually and keeping a record at least once a day. If the monitoring of the temperature is done manually then there is a higher chance of error hence, it is better to use the temperature data loggers of our company especially designed to monitor the temperature of the cooler box. The data loggers of Vacker UAE are very easy to use and the measurement can easily be recorded and stored in a computer. The user can easily set the desired minimum and maximum temperature for the cooler box. The data loggers can be used in cooler boxes as well as vaccine fridges, medical freezers, etc.

Tips for proper monitoring of temperature in a cooler box

  • The building of ice in the cooler should be avoided as the ice build-up affects the potency of the vaccine.
  • The temperature is most stable in the middle of the cooler box hence, it is best to keep the vaccines alongside the middle of the cooler.
  • The cooler box should always be used from a reliable medical company.
  • The data loggers’ power supply should be checked on a regular basis.

Temperature mapping for FMCG storage areas

temperature mapping for FMCG storage areas

We carry out temperature mapping study or thermal mapping study on FMCG warehouses. Most of the items under the FMCG category are temperature sensitive products. FMCG wholesale distributors store suchtemperature-mapping-of-food-storage-freezer  items in their warehouses, cold rooms or freezers. They need to store such items under controlled temperature as recommended by the manufacturer. In layman’s language, temperature mapping study is the verification of uniformity of temperature distribution across a storage area.

Why is temperature mapping study required for FMCG storage warehouses?

We will consider an example of a nutrition product stored in an FMCG (Fast Moving Consumer Goods) warehouse. The manufacturer specifies that the ideal storage condition of this product is below 25 Deg Centigrade. If the temperature in the warehouse does not

The requirement of temperature mapping study is to ensure that the entire area maintains temperature-mapping-of-baby-food-warehousethe required temperature. You may have a proper HVAC (Heating Ventilation and Air conditioning system) system to keep the temperature below 25 Deg. Centigrade. It can also be a freezer which maintains -20 Deg. Centigrade. The controller of the HVAC system may be located at one corner of the warehouse. How do you know that all areas of your warehouse are within 25 Deg C? It is generally difficult to maintain if the system is not designed and implemented properly. It is always possible that one area of the warehouse may be at 30 Deg C, certain other areas at 20 Deg C and the area near the controller is at 25 Deg C.

So it is possible that you will be unknowingly storing a product in an area having a temperature of 30 Deg C. You might be thinking that the area is at 25 Deg C because you have set the controller at 25 Deg C. If you keep this product at this location for couple of weeks, it may lose its properties and you will never know about it.temperature-mapping-of-processed-food-warehouse

A Temperature mapping study is carried out on such FMCG storage areas to study such situations. After carrying our this study, you can understand the temperature distribution pattern inside your warehouse, cold room etc.

Examples of FMCG storage requiring Thermal mapping study

Thermal Mapping study is also known as T Mapping. Warehouses, cold rooms, walk-in freezers etc. require T Mapping study. The following types of assets are normally covered:

  1. Warehouses having a temperature level of maximum 25 Deg C. (77 Deg F).temperature-mapping-of-cheese-freezer
  2. Freezers having a temperature level of -20 Deg C (minus 20 Deg C or minus 4 Deg F).
  3. Freezers having a temperature level of -25 Deg C (minus 25 Deg C or minus 13 Deg F).

Typically the following are the type of products:

  1. Processed foods , ready to cook foods, cooked foods.
  2. Tinnes and canned food items such as tinned Tuna, tinned Beef etc.
  3. Soft drinks, aerated drinks etc.
  4. Health drinks
  5. Health supplement products.T-mapping-of-food-warehouse
  6. Nutrition products.
  7. Toiletries such as toothpaste, mouthwash and oral care products.
  8. Cosmetic products, skin care products.
  9. Over the counter drugs which do not require a prescription.
  10. Dairy products such as cheese, butter etc.
  11. Baby care items, baby food etc.
  12. Chocolate, candies, biscuits, cookies, ice cream,  etc.

Methodology of T-Mapping study

Protocol for T Mapping study of FMCG areas is similar to those of Medicine storage areas. The basic procedure is to install numerous data loggers around the warehouse or cold room. These data loggers will record the temperature thermal-mapping-of-FMCG-warehousefor a couple of days or weeks based on the type of asset. At the end of the period, the data will be downloaded and analyzed to check the temperature distribution. The report will consist of all these data and graphs to indicate the results. The reports will show hot and cold points of the area.

Where to place continuous temperature recording systems in FMCG warehouse or cold room?

The warehouse operator has to install proper temperature recording systems in such areas. This is to record the temperature data continuously. Temperature mapping study is an activity to analyze the proper temperature distribution. A temperature recording system is to record the data continuously and the operator can regularly keep the record of temperature-mapping-study-cold-storagethe temperature. This will be required for auditing purposes also.

We will be identifying hot and cold points of the area. The warehouse operator has to install a recording system at these hot and cold points. They may have to download the data periodically and maintain proper records.

We supply wireless temperature recording systems or LAN based wired recording systems for such warehouses. Visit us at to learn more about our services.

Why cold rooms and walk in freezers have a high humidity?

cold rooms and walk in freezers

You might have experienced many times that your cold room or walk in freezers have a very high humidity. This is especially applicable for medicine cold rooms of 2-8°C, cold room used for fruits or vegetables etc. below 10°C etc. The problem is severe for a cold storage operating between 0°C to 15°C.

Why my medicine cold room has a very high humidity?

Humidity is basically moisture particles in the air. If you have a high concentration of moisture particles in the air, this means that the room is having a high humidity. Humidity is measured as a percentage of moisture particles in the air.cold-room-dehumidifier-vacker

The cold room is always at a much lower temperature compared to its immediate. The air in any environment has a certain amount of moisture at all times. Even if you are in a dry country, you will have a humidity level of 30-40% RH.

Let us assume that you have a cold room of 2-8°C, which opens to a warehouse having a humidity level of 50%RH. The warehouse may be at a temperature of 25 to 30°C. There will be a certain level of moisture in the warehouse. When you open the doors of a cold room, it attracts fresh air from the warehouse. Since the cold room has a lower temperature, the moisture in the air condenses inside the cold room, thus increasing the humidity. Every time you open the cold room, it attracts more moisture particles into the cold room. This process is called condensation.

If you have a cold room humidity monitoring system inside your cold room, you can see that as soon as you open the door, humidity increases within seconds.

Thus the humidity keeps on increasing and will reach even 95-100%

What is the recommended humidity for medicine cold rooms?

Fro storage of medicines, the recommended humidity level is below 65%. However, this also depends on the type of medicines that you are storing. If you are unsure, please check with the manufacturer of the medicine. We have undertaken dehumidification projects of cold rooms, which required a humidity level of 45%.

How to reduce the humidity of cold rooms?desiccant-dehumidifier-for-cold-room-vacker

One way to reduce the humidity of a cold room is to limit air flow into the cold room from the outside. However, as you can imagine this is very difficult. You can install air curtain in front of the doors of the cold room, but is not very effective.

The next way is to remove humidity from the room by using a dehumidifier. This is the only way to effectively reduce the humidity of a cold room. Dehumidifiers are electrical devices which process the air and convert the moisture particles into water and remove from the room. Below 10°c, you have to use a desiccant type dehumidifier.

How to select the size of the correct dehumidifier for my cold room?

You need to calculate based on your room size, present temperature and present humidity. We will assist you to decide the exact capacity of the dehumidifier. If you wish, you can use our free dehumidifier calculation tool and read more on cold room dehumidifiers.

Dehumidification for food industry

dehumidification for food industry

Dehumidification in the food industry to preserve the quality of food, especially packaged foods. Also, the shelf life of processed food is reduced if moisture gets into the food. In modern plants, the processing machinery is capable of creating a vacuum during the process, preventing entry fo moisture. However, it is safer to reduce the moisture of the environment for any such applications.Chocolate-factory-dehumidifier

Applications of dehumidifiers in food industry

Few of the applications of food dehumidifiers are as below.

  1. During the process of confectionary and bakery items such as sweets, it is necessary to keep a low humidity level. During packing the items, if moisture enters into the packing, the life of the item is drastically reduced.
  2. Processing and packaging of dates also require low humidity environment to keep the quality and to have a longer life.
  3. In the processing plants of meat and poultry, condensation of air happens if the moisture content is high. This will affect the machinery as well as the quality of the process. Hence the standards including HACCP standards recommend low humidity levels. We recommend condensation dehumidifiers for meat processing and poultry processing industries.meat-factory-dehumidifier
  4. Reducing the humidity can lower the frost and ice formation on the stored goods.
  5. During the manufacture of chocolate also, the moisture should be very low up to the wrapping process. As you can imagine, if the chocolate absorbs moisture before individual wrapping, the chocolate will be spoilt in a couple of days. So chocolate factories definitely require dehumidifiers.

Which types of dehumidifiers to use in the food industry?

The major types of dehumidifiers are just processing the internal air and recirculating. In such cases, there will not be any fresh air intake from outside. There are types which take fresh air from outside and process before passing into the food processing area. If you are using such a machine, you will need additional filters before the air intake to ensure the quality of the air which comes into the processing

By way of operation, there are two types of dehumidifiers viz. condensation dehumidifiers and desiccant dehumidifiers. Generally for a low-temperature application we use desiccant dehumidifiers (Typically below 10°C). For all applications above 10°C, we can consider condensation dehumidifiers. However, this is only a general guideline and please contact us for a free evaluation.

Reduce Frost and ice formation on stored goods

The food industry involves cold rooms, walk-in freezers, ultra low freezers etc. In all such cases, frost and ice formation happen on the stored goods. This is due to the solidification of the moisture particles.  This causes inconvenience to the operators, increase the energy cost etc. A dehumidifier can drastically reduce this problem by reducing the moisture content in the air.

Reduce defrost cycle of cooling units

As you may know, the cooling units in the cold room and walk-in freezers go into defrost cycles, a couple of times a day. This is to defrost the ice, failing which the machine may fail causing internal damage. By reducing the moisture in the air, it is possible to reduce the defrost cycle, thus saving energy cost as well.

VackerGlobal supplies all types of dehumidifiers in Dubai, Abudhabi, Sharjah, Alain, Ajman, Ras Al Khaimah etc. Also, we supply these dehumidifiers in other Middle East countries covering Saudi Arabia (Riyadh, Dammam & Jeddah), Doha, Muscat, Kuwait, Bahrain etc. through our own offices or through distributors.
