Water defrost evaporator
Zhexue water defrost evaporator is where heat exchange occurs and the refrigerant absorbs heat from the surrounding air or liquid, resulting in cooling. Evaporator defrosting is the process of removing ice or frost that has accumulated on the surface. Water defrost evaporator means we will use the hot water from the machine to defrost. Hot water circulates through the evaporator in a closed loop, melting the frost and carrying away the resulting water. This method is often used in smaller refrigeration systems and can be cheaper than hot gas defrosting.
Regardless of the method used, the water defrost evaporator must be defrosted regularly to maintain its efficiency and prevent potential problems. The frequency of defrosting depends on factors such as ambient temperature, humidity level, and usage pattern of the refrigeration system. Under normal circumstances, when the frost or ice thickness is about 0.5 to 1.5 inches, the evaporator should be defrosted. With proper maintenance, your refrigeration system can provide reliable cooling, saving you money in the long run.
Main features
1. Fins stamping equipment adopts scientific mold, using15.88mm pipes,9.52mmand 12. 7mm inner thread pipes, it reduce the wind resistance.
2. All evaporators are equipped with the international brand external fan motors.
3. All evaporators are equipped with best brand s/s ele. Heaters to defrost quickly.
4.Using 15.88mm copper pipe and 12.7mm inner thread copper pipe, special length between pipes and advanced technology of heat exchange surface make our evaporator more efficiency.
5.Fins stamping equipment adopts scientific mold , using 15.88mm pipes and 12.7mm inner thread pipes, it reduce the wind resistance.
6.Equipped with the extended wind guide,it can improve the motors efficiency and raise the air flow (motors more than 500mm)
7.We have windshield at the bottom of the fan coils, it can prevent the air through the water tray,then more wind will through out the fan coils to improve the heat exchange efficiency.
8.All evaporators are equipped with the international brand external fan motors.
9.Optimized pipe rows and lines design and different liquid distributor can improve the heat exchange efficiency based on the different condition.

FAQ
Q: What is your delivery time for normally products?
A: Usually for condensers and evaporators, delivery time is 7 days, but if you change the components, that would be longer.
Q: Do you provide sample? Is it free?
A: If the sample is low value, we will provide the free sample with freight collect. But for some high value samples, we need to collect the sample charge.
Q: Can you do our own packaging?
A: Yes, you only need to provide the package design and we will produce what you want. We also have professional designer who can help you with the packaging design.
