Screw Compressors Rack Unit


Features

l Less space occupied, simple operation and quick installation

l Low pressure stage has no oil separator or oil cooler, which assist to reduce operation and maintenance costs.

l Low pressure stage is equipped with a small motor, without considering its start

l The unit has strong independence. Single unit application and also several units used in parallel

l Automatic control, high motor efficiency, the system has good safety and reliability.

l Adopting an improved two-stage compression intermediate throttle incomplete cooling cycle, two subcooled, operation more economical

l Adopt full differential pressure oil supply, no oil pump consumption and exclude oil pump failure

l There are 30 kinds of combinations, select the best inner volume ratio according to different conditions, different refrigerants.

l Initial operation only has high pressure stage, and can run at full capacity in fast cooling speed and economical.

l Adopt two compressors and motors. In most condition, 380V low-voltage motor can meet requirement, which will assist to reduce cost.

l Adopt our generation Ⅲ screw compressor in mature technology and  low maintenance costs

 


Optional

l Optional PC control

l Thermal siphon oil cooler
