Product Description
1.Brief introduction-condensing units
1)Adopt world famous Bitzer semi-hermetic two stage compressor,with high reliability;
2)With high efficiency and long life cooper tube fin type air cooled condenser,or shell and tube water cooled condenser;
3)Air cooled unit condenser adopts high quality low noise;
4)High quality refrigeration parts are employed;
5)Adopt intercooler to increase unit cooling capacity and EER value;
6)With lower evaporative temperature:it can reach -50ºC when system use R22 refrigerant;and it can reach -65ºC when system use R404A refrigerant;which can be used in cryogenic box,quick-freeze equipment etc;
7)Other kinds of power supply not mentioned in the specification is optional,such as 220/440/460V-3Phase-60Hz.
