China Air Cooler Series - Efficient Water Defrosting, Corrosion-Resistant, Low Noise | Reliable Suppliers & Factory
Product Features
Panel and side plates are well constructed by using step structure, reducing the noise caused by fan and fan vibration. Water pan and side plate are easy to dismantle.
After treatment of phosphating and surface spray, the shell becomes corrosion resistance, smooth and achieves a longer life span.
Automatic molding process ensures dry and clean interior of the copper tube.
2.6mpa air tightness test satisfies product air tightness requirements.
Expanded by liquid pressure machine, the aluminum fin and copper tube are combined tightly and achieves a stable effect of heat transfer.
Famous brand fan and heat tube achieves stable quality, low noise, less energy consumption and high efficiency.
Slot type rack design convenient for installation.
All wires and plugs are connected in an electrical box, convenient for installation and maintenance.
Electric defrosting selects high insulation performance stainless steel heating tube. Reasonable distribution achieves short time defrost, high efficiency and low consumption. Users can add module in the controller to realize the automatic defrosting control. Fast efficient defrosting and less energy cost.

Frequently Asked Questions
How does the air cooler reduce fan and vibration noise?
The panel and side plates are constructed using a step structure, which effectively reduces the noise caused by the fan and its vibration. Additionally, the water pan and side plate are designed to be easily dismantled.
What treatment is applied to the shell to prevent corrosion?
The shell undergoes phosphating and surface spray treatment, which makes it highly corrosion-resistant, smooth, and ensures a longer product life span.
How is the air tightness of the cooling unit tested and guaranteed?
Each unit undergoes a rigorous 2.6mpa air tightness test to satisfy and guarantee all product air tightness requirements.
What type of defrosting system is used in these products?
The unit utilizes an electric defrosting system with high-insulation stainless steel heating tubes. Its reasonable distribution achieves short defrost times, high efficiency, and low energy consumption. Users can also add an automatic defrosting control module to the controller.
What are the baseline temperatures for SDJ, SDD, and SDL cooling capacities?
- SDJ: Based on an air inlet dry-bulb temp of -25℃, evaporation temp of -31℃, and refrigerant liquid temp of 20℃.
- SDD: Based on an air inlet dry-bulb temp of -18℃, evaporation temp of -25℃, and refrigerant liquid temp of 20℃.
- SDL: Based on an air inlet dry-bulb temp of 0℃, evaporation temp of -8℃, and refrigerant liquid temp of 30℃.
- SDD: Based on an air inlet dry-bulb temp of -18℃, evaporation temp of -25℃, and refrigerant liquid temp of 20℃.
- SDL: Based on an air inlet dry-bulb temp of 0℃, evaporation temp of -8℃, and refrigerant liquid temp of 30℃.
