Application of Dehumidifier in Cold Room

Dehumidification of your cold storage will make the atmosphere better and more hygienic by keeping the floors dry, preventing ceilings from dripping on personnel and produce, and ensuring that doors without ice build-up seal correctly.

Staff participation in frost and ice removal has a direct financial impact due to lost productivity, yet it is necessary to meet Health and Safety regulations. Defrost cycles for evaporators (whether by electricity or hot gas) can be expensive in terms of energy and the potential influence on cold storage temperatures.

Hence, dehumidification technologies in cold storage rooms is the ultimate solution as it has no drawbacks. It will be difficult to remember how you managed without one when you have one operating for you. In dehumidified cold storage, health and safety regulations are simpler to maintain, and you save money on energy and salaries. 

Importance of Dehumidifier in Cold Room

Goods are continually arriving and departing the cold storage due to the function of these facilities. Humidity penetrates the facility each time a truck docks in the form of warmer, ‘wetter’ peripheral air. This combines with the air inside the cold room and condenses on all of the chilly surfaces it encounters.

When the temperature drops below freezing, condensation forms as ice (and snow) on all inside surfaces, including fork trucks, racks, and the product itself.The accumulation of ice and snow is ongoing. To minimize tripping and slides, forklift accidents, and frozen evaporators, cleaning the walls and ceilings has become a frequent and time-consuming task.

The impact that frost can have on electronics on MHE and weighing machinery is in contrast to this clear, visible concern. If precautions are not made to avoid the build-up of ice, it can trace down wires, resulting in signal shorting or signal loss.

Managing this issue with active dehumidification of the air entering the cold room or storage is an extremely efficient strategy. The associated changes in humidity contained by the air at these limits are significant, with interior and exterior temperature distinctions ranging from -28 to as high as 30°C in summer.


The outdoor atmospheric relative humidity might be as high as 14g/kg or even more during the summer. This extra humidity has to go someplace, so it condenses on colder objects and freezes if the temperature falls below 0 degrees Celsius.

Advantages of Dehumidifier in Cold Room

Dehumidification of your cold room will improve the atmosphere better and more hygienic since the flooring will keep hydrated, the ceilings will not drop on workers and produce, and the doors will lock correctly avoiding ice build-up.

Dehumidification can also help your refrigerator system run more efficiently since it won’t have to deal with as many defrost cycles due to moisture and ice build-up.Dehumidification technologies in cold room facilities have no drawbacks.

It will be difficult to remember how you managed without one once you have one functioning for you. In dehumidified cold room, health and safety regulations are simpler to fulfill, and you conserve money on energy and salaries.

Followings are some of the specific advantages about dehumidification technology in cold room:

Products wrapped up in packaging are no longer covered in ice.

The number of defrost cycles is drastically decreased.

The safety situation improves.

Helps to reduce operating costs.

Energy usage is reduced.

Conveyor damage due to ice buildup is prevented.

Types of Dehumidifiers for Cold Room

Depending on the application, there are two types of dehumidifiers available suitable for cold room:

1. Rotary dehumidifiers using desiccant technology

This works by absorbing humidity from the air with silica gel desiccants. Humidity is present in the air intake, which is removed by the desiccant. The humidity is absorbed by the desiccant, and the output air is dry. There are several types that can work in temperatures as low as -15°C. We like to use these types of dehumidifiers for chilly rooms because the temperature is usually about 5°C.

2. Condensing Type Dehumidifier

Dehumidifiers of the condensing kind work by condensing humidity and turning it to water. The water will subsequently be immediately drained or pushed through a dehumidifier-connected automated pump. Dehumidifiers of this sort are designed for temperatures over 10°C and may thus be used in warehouses.

How do you choose the right dehumidifier capacity and type?

We will need the following information to figure out how big dehumidifiers should be:

The area's measurements

Ideally, data on current temperature and humidity conditions.

Specifications of the current cooling units (HVAC).

Desired Humidity level

As a result, dehumidification in cold room distribution facilities may benefit productivity, energy costs, bottom-line profit, and health and safety. It reduces the amount of time and effort required to physically remove ice and snow, resulting in personnel and wage savings.

It improves your operation’s efficiency while maintaining product and equipment quality.The risks of operating machinery that has ice accumulation are obvious. By removing these possible threats, the process becomes more efficient.

Finally, installing a dehumidifier in a cold room will conserve money in the long term, decrease plant and material handling equipment downtime, and provide a safer and more comfortable workplace environment for your employees.
