At the core of the cold chain world, a huge contradiction has always existed: Low temperatures can delay spoilage, but the condensed 

water vapor has become the "invisible killer" for preservation. Conventional dehumidifiers will "break down" in low-temperature 

environments and even freeze and become paralyzed. The emergence of anti-low-temperature dehumidifiers is precisely to solve this 

industry pain point. It is not just a machine, but also the "smart brain" for maintaining the balance of temperature and humidity in the 

cold storage environment. 

Why does a cold storage facility need its own "cold-resistant warriors"?

Ordinary dehumidifiers will quickly accumulate frost on the evaporator fins in low-temperature environments (usually below 15℃), and 

the machine needs to frequently activate the "frost removal" program, resulting in extremely low dehumidification efficiency or even 

complete failure. However, cold storages, especially fruit and vegetable preservation storages, maintain a temperature of 0℃ to 8℃ in 

a high-humidity environment for a long time. 

Here, excessive moisture means: 

Fruit and vegetables rot more quickly: The condensed water droplets provide a breeding ground for mold and bacteria. 

Quality decline: Leafy vegetables wilt, fruits change color, significantly reducing the value and taste of the products. 

Safety hazard: The floor and shelves in the warehouse are icy, increasing the risk of people slipping; the ice layer also increases the load 

on the equipment and raises energy consumption. 

Therefore, a professional device that can "resist freezing" and efficiently dehumidify is of vital importance. 

Break ice and dehumidify, hardcore performance builds the "fresh" machine defense line.

The low-temperature dehumidifier is specially designed for harsh environments. Its outstanding performance is reflected in 

the following aspects: 

Core Technology: Efficient Anti-Freeze System

It adopts intelligent defrosting control technology and a special hydrophilic coating evaporator, significantly delaying the rate of frosting. 

Even when frosting occurs, it can achieve rapid and efficient defrosting through precise reverse circulation defrosting or hot air bypass 

technology, maximizing the effective dehumidification operation time at low temperatures. 

Wide temperature range strong dehumidification

This truly low-temperature resistant dehumidifier can operate stably within a wide temperature range of -30℃ to +30℃. The dehumidification 

capacity fluctuates minimally with temperature changes. In the core temperature range of 0-8℃ for a refrigerated storage facility, it still 

maintains an astonishing water removal efficiency, easily handling environments with over 95% humidity. 

Precise intelligent control

Built-in high-precision temperature and humidity sensors, which can set the target humidity value and operate automatically. Once the 

humidity in the warehouse exceeds the set value, the machine will immediately start and firmly maintain the environmental humidity 

within the optimal range for fruit and vegetable preservation (typically 85%-95% RH), achieving fully automatic, unmanned operation. 

Energy-saving and environmentally friendly, durable and sturdy

The core components such as the high-efficiency compressor and fan are adopted, resulting in lower energy consumption. The body and 

components have undergone rust-proof and corrosion-proof treatment, enabling them to withstand the corrosive environment of high 

humidity and low temperature for a long time, and have a longer service life.

Case Study: The "Fruit and Vegetable Preservation Technique" in the Cold Storage

Let's focus our lens on a common application scenario - the fruit and vegetable preservation warehouse in a large-scale cold storage center. 

Challenge:

The temperature of this preservation warehouse is set at 3℃, and it is used to store high-priced strawberries and leafy vegetables. The 

external environment of the warehouse is hot and humid. When people enter and exit or when goods are transported in and out, a large 

amount of humid and hot air will be brought in, causing the humidity inside the warehouse to remain above 95% for a long time. 

Condensation water constantly forms on the ceiling and walls. The surface of the strawberries becomes damp, making them prone to 

white mold diseases. The green leafy vegetables also start to turn yellow and rot, with the loss rate reaching as high as 15% at one point. 

Solution:

Following the suggestion of the warehouse engineer, the center installed two large low-temperature resistant dehumidifiers in a 600 

cubic meter warehouse. 

Effectiveness: 

Precise humidity control: The equipment maintains the humidity inside the warehouse at a stable level of 90% ± 3%, within the optimal range. 

The surface of strawberries becomes dry and clean, and green leafy vegetables no longer have water stains or rot. 

Significant improvement in quality: The shelf life of strawberries has been extended by 5-7 days, with bright colors and intact flavor; the 

green leafy vegetables are lush and upright, and wilting has largely disappeared. 

Significant reduction in losses: The loss rate of fruits and vegetables has decreased from 15% to below 4%. Just this one factor alone has 

saved the center tens of millions of yuan in economic losses in just one month. 

Environmental improvement: The floor and shelves inside the warehouse are no longer icy, eliminating potential safety hazards and allowing 

staff to operate with greater peace of mind. 

The administrator happily stated: "It's like installing a 'dehumidification air conditioner' in the cold storage. No matter how hot and humid 

it is outside, the inside remains fresh and clean. The fruits we send out are exactly the same as when they leave the warehouse, and our 

reputation and profits have both improved!" 

Conclusion

In today's era of emphasizing quality and efficiency, low-temperature dehumidifiers are no longer optional accessories; instead, they have 

become standard equipment in modern cold storage facilities, especially in areas such as fruits and vegetables, medicinal materials, electronic 

chemicals, etc., where humidity sensitivity is a critical factor for storage environments. They quietly stand below the freezing point, resisting 

the erosion of moisture, and safeguard not only the quality of the products but also the core competitiveness and valuable profits of the enterprises. 

Investing in a professional low-temperature dehumidifier is to inject a reliable "drying" force into your cold chain system, ensuring that food 

preservation is worry-free.
