Cold Room Evaporator
We specialize in designing and manufacturing evaporators including single and double-side blow evaporators, tailored to your specific cooling area needs from low to high capacity cold storage.
We can configure different series of evaporators according to different temperatures of cold storage to ensure optimal performance.
- Cold Room Temperatures: -5℃to -35℃(23℉ to -31℉)
- Cooling Area: 7㎡-800㎡
- Heat Exchange Capacities: 2kW to 150kW
- Defrost: Water or Electric Defrost
Based on Temperature
Chiller Evaporator
- Designed for chiller cold rooms, DL series evaporators help maintain a stable, moderate temperature range, ensuring that products stay fresh without freezing.
- Temperature: -5°to 5°C (32℉ to 41℉)
- Cooling area: 10-800㎡
- Capacity: 2.1-152kW
Freezer Evaporator
- Built for freezer cold rooms, DD series evaporators provide a steady, deep cooling environment to preserve products at freezing temperatures for long-term storage.
- Temperature: -18°C to -5°C (0℉ to 23℉)
- Cooling area: 7-600㎡
- Capacity: 1.4-105kW
Blast Freezer Evaporator
- In blast freezer cold room, DJ series evaporators offer quick, powerful chilling, maintaining the texture of food, by preventing the production of ice crystals.
- Temperature: -35°C to -25°C ( -31℉ to -13℉)
- Cooling area: 7-415㎡
- Capacity: 1.2-68kW
Based on Defrost Method
Water Defrost
- Water defrost evaporator uses hot water to melt accumulated frost on the evaporator coils. In addition to being so quick, they also aid to maintain coil cleanliness.
- Water volume: 2-17.4T/h
- Defrost Time：Set according to the specific cold room situation
Electric Defrost
- Electric defrost evaporator removes frost using U-shaped stainless steel heaters on the coils. And electric defrost is more common in low-temperature applications.
- Coil power: 0.5kw-40kw
- Catchment tray: 0.5kw-5.6kw
- Defrost Time：Set according to the specific cold room situation
Based on Design
Single Side Blow
- A single side blow evaporator has two fans that blows air across the evaporator coils from one side only, ensuring airflow in one direction. This type is typically used in smaller cold rooms where space is limited and airflow needs to be directed more evenly across the room.
Double Side Blow
- With its axial fan motor and double-side wind-blown design, our double-side blow evaporator ensures balanced airflow and better cooling distribution. It also produces low noise and soft blowing. Perfect for a hotel, supermarket, or food processing workshop.
Based on Mounted
Ceiling Mounted
Ceiling mounted evaporators are recessed in the ceiling, offering a more uniform distribution of cool air. This installation improves comfort by evenly cooling the room without occupying floor or wall space.
- Suitable for single and double side blow evaporators to install.
Wall Mounted
Wall-mounted evaporators save floor space by being installed high on walls. Installation is simple, requiring only securing the unit to the wall and connecting refrigerant lines.
- Suitable for single side blow evaporators to install.
Floor Mounted
Floor mounted evaporators are ideal for spaces where wall or ceiling installations aren’t possible, offering easy access for maintenance, without requiring ladders or complex setups, ensuring convenience.
- Suitable for single side blow evaporators to install.

FAQ
How does a cold room evaporator work?
In order to evaporate and absorb heat from the air, the refrigerant is circulated through coils in the evaporator. To maintain the proper temperature, the cool air is then dispersed throughout the chilly chamber.
Which temperature range is best for evaporators in cold rooms?
Cold room evaporators typically operate in the temperature range of -5°C to -18°C, depending on the application (e.g., storing meat, dairy, or frozen foods).
How can I choose the best cold room evaporator for my location?
Choosing the right evaporator depends on factors like room size, desired temperature range, and airflow needs. Larger rooms may require a double side blow unit, while smaller rooms might benefit from a single side blow or wall-mounted unit.
If there is insufficient cooling from the evaporator, what should I do?
If the evaporator is not cooling effectively, check for common issues such as dirty coils, low refrigerant levels, malfunctioning fans, or poor airflow. Professional servicing may be required to address underlying problems.
How should a cold room evaporator be maintained?
Cleaning the coils, monitoring refrigerant levels, testing fans for correct operation, and making sure there are no obstructions in the airflow are all part of routine maintenance. Regular defrosting is also necessary for efficient operation.
When should I clean the evaporator in my cold room?
It’s recommended to clean the evaporator every 3-6 months, depending on the level of use and dust accumulation. Regular cleaning helps maintain optimal cooling efficiency and extends the life of the evaporator.
Can I install a cold room evaporator myself?
A cold room evaporator can be installed by someone with HVAC experience, but it is advised to contact a professional to guarantee correct installation, maximum performance, and adherence to safety regulations.
