Product Description

 

DD/DL/DJ Series Copper Tube Refrigeration Unit Cooler Evaporator for Cold Room

D-series Air-cooler is one kind of storage cooling equipment used in freon refrigeratiunits, according to applicabie temperature, there are 3 series including dl, dd and DJ, which can be used at aifferent storage temperatures. Dl type air-cooler is mainly applicabie to about 0 fresh-preserved storehouses; Dd type air-cooler is mainly applicabie to about -18 cold storages; DJ type cooling fan is mainly applicabie to quick-freezing storages below -25.


General Features:

The high efficient coils are made from high quality copper tube 9.52mm and special profile aluminium fins. Heat exchangers are supplied clean and tested  under a pressure of 30 bars.

The Casing:

White powder coated aluminium, high corrosion strength, impact resistance, and does not produce polluting debris.

The Fan Motors: 

All with high quality axial fan motors with high safety standards fitted well to the unit casing with an anti-vibration system

Electrical parts and wiring:

Are connected to an earth terminal, carried out in junction box with access holes equipped with water-proof cable grands. All materials are selected carefully for long-term reliability.
