D-series air cooler is a supporting cooling equipment freon refrigerating unit to use the library, by the use of temperature to distinguish; distinguish into DL, DD, DJ, three series. Can be separately applied different libraries temperature, the DL type cooling fan is mainly applied to about 0℃ storage house; the DD type air cooler is mainly applied to the -18℃ refrigerator; DJ-type cooling fan is mainly applied in quick-frozen below -25℃ library. Designed for fresh, frozen, refrigerated and design. Shell is made of high-quality steel plate, phosphate electrostatic spraying process, corrosion-resistant, beautiful appearance; Bright brass coil the wrong row layout design. Mechanical expansion process, the copper pipes and fins closely integrated, better heat transfer; High efficiency, low energy consumption shimmer external rotor motor air volume, long-distance low noise, stable and reliable.
