7.5HP 3 fan refrigeration air cooler evaporator coil on sales from china for cold room, cold storage
D-series Air-cooler (evaporator) is espcially designed for preservation, refrigeration and cold storage rooms, there are 3 series including DL, DD and DJ,which can be used at different storage temperatures with different fin spacing.
DL type air-cooler is mainly applicable to about 0°C fresh-preserved storages;
DD type air-cooler is mainly applicable about -18°C cold storages;
DJ type cooling fan is mainly applicable to quick-freezing storages below -25°C.
Shell made by painted galanized steel, good anti-corrosion
Stylish design and appearance
High quality mechanical expanding expanding between copper tube and fins, tight contacting and optimized heat exchanging.
With super high temperature vacuum drying for coils, ensure inner without impurity or water substance.
Electrical heating tubes made by good stainless steel are distributed evenly in coiled pipes, ensures excellent defrosting. Electrical heating tubes are deforsted by close connecting electrical aluminum bushing and fin holes, as as result, heat is radiated easily, ensures long service life for fan motor.
Reasoanble design width, space between fan blade and aluminum fin is larger than 1/3 diameter of fan blade in order to ensure sufficient effective air volume
Long distance air supply ducts can be used according to customer request.
