30HP Air cooled chiller
Lechang series of low-temperature water chiller can be divided into three series: H(high temperature), M(medium temperature), L(low temperature) which evaporating temperature is -10℃/-20℃/-50℃. Different compressors and other parts make up different series of chillers. The same compressor in different conditions is not the same, so choose the proper chillers according to the detailed requirements. In order to prevent the frozen of water , ethylene glycol needs to be added to the cooling system. The concentration of ethylene glycol can not be less than 20%(H), 30%(M), 40%(L) in order to ensure the normal operation of chillers. According to customer’s specific requirements, chillers with evaporating temperature less than -60℃ can be made.

Remark:
1.The cooling capacity is based on: chilled water inlet and outlet water temperature 12 C / 7 C, cooling inlet and outlet water temperature 30 C / 35 C
2.range of work:Chilled water(Temp range):5℃-35℃;inlet and outlet water(temp range) :3℃-8℃.working environment: ≤35℃(condensation Temp)
3.Conversion of units:1kw cooling capacity=860kcal/hr
1RT=3024kcal/hr 1kcal/hr=3.969BTU/hr 1HP=0.735KW
