Product Description

D Series Cold Room refrigeration  Unit Cooler

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.

This series product is equipped with features as follows:
This kind of cooling fan is specially designed for preservation, refrigeration and cold storages;
1. The shell is made of quality steel plate; Sprayed plastic surface is anti-corrosive, and its appearance is handsome;
2. Coiled pipes are mechanical expanding tubes in staggered arrangement; Therefore, copper tubes and aluminum sheets are combined cioseiv, and ensure good effect of heat exchange. Electrical heating tubes made of good stainless steel are distributed evenly in coiled pipes, and thus ensureexcellent defrosting effect. Electrical heating tubes are defriosted by closely conecting Electrical aluminum bushing and holes of fins, as a result, heat is dissipated easily, and thus fan boasts long service life.
3. The design width of this cooling fan is reasonabie, space between fan biade and aluminum fin is larger than 1/3 diameter of fan blade in order to ensure sufficient effective air volume;
4. Long-distance air supply ducts can be used according to customers'requirements;
5. For special-purpose prodcts, please contaes agencies of gaoxiang company.
