This is one of the components of freezer and is a device that evaporates liquid refrigerant expanded by an expansion valve to cool other fluids such as air, water, and brine by depriving the evaporation heat from the surroundings. Our Evaporator is a high-efficiency micro channel hydrophilic coating heat exchanger, which is a smart product that improves water drainage, durability, thermal efficiency, miniaturization and light weight.
