Description: D Series DD Type Medium temperature standard air cooler |
Products features: |
D-series Air-cooler is one kind of storage cooling equipment used in freon refrigerating, according to applicable temperature, there are 3 series including DL, DD and DJ,which can be used at different storage temperatures. 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 |
This series product is equipped with features as follows: |
1-This kind of air-cooler is specially designed for preservation,refrigeration and cold storages; |
2-The shell is made of quality steel plate;sprayed plastic surface is anti-corrosive, and its appearance is handsome; |
3-Coiled pipes are mechanical expanding tubes instaggered arrangement;therefore, copper tubes and aluminum sheets are combined closely, 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 defrosted by cosely conecting electrical aluminum bushing and holes of fins as a result, heat is dissipated easily, and thus fan boasts long service life. |
4-The design width of this cooling fan is reasonable, space between fan blade and aluminum fin is larger than 1/3diameter of fan blade in order to ensure sufficient effective air volume; |
5-Long-distance air supply ducts can be used according to customers' requirements; |
Technical Parameters:
When Tr=-25°cand Δt=10°c
R134a energy should multiply correction factor f
that is QOR134a=QOR22×f
