Sell Middle /double temperature piston parallel units

Detailed Product Description --High efficiency,cost-saving the average efficiency of tandem unit is 30-50%high compared with single unit according to different refrigeration system PLC controller adjust the amount of the working unions according to the level of the air return pressure Meticulous design of the pipeline lowest the loss of pipeline pressure and increase the efficiency of heat exchanger utmost.--Compact construction Compressor, reservoir, gas-liquid separator, oil separator, air-returning header, general feed pipe, control panel are integrated together to save the operating space. With the high integration design concept, we reduce the amount of the pipelines, the wastage of the cables and the construction period.--ReliableHigh quality screw compressor and piston compressor. High quality controlling valve parts. High efficient gas-liquid separator and unique design of pipelines prevent the possibility of liquid slugging of the compressor. Selectable assemblage of long-distance output port offer monitoring of unions and system operation mode by our experts.Application:Apply to low temperature cold store and quick frozen store, and air-conditioner system.
