Refrigeration Capacity:153~1526.3kW(R717)
working condition:-35℃~40℃
Widely used in food refrigeration and freezing， dairy， ocean fisheries processing，cold chain， logistics， cold storage， chemical industry， polycrystalline silicon，electronics， aerospace， pharmaceuticals， coal etc.field.It is the first selection for low temp and ultra-low temp application of-55℃~-30℃.
*Less space occupied，simple operation and quick installation
*Low pressure stage has no oil separator or oil cooler， which assist to reduce operation and maintenance costs.
*Low pressure stage is equipped with a small motor， without considering its start
*The unit has strong independence.Single unit application and also several units used in parallel
*Automatic control， high motor efficiency， the system has good safety and reliability.
*Adopting an improved two-stage compression intermediate throttle incomplete cooling cycle，two subcooled， operation more economical
*Adopt full differential pressure oil supply， no oil pump consumption and exclude oil pump failure
*There are 30 kinds of combinations， select the best inner volume ratio according to different conditions， different refrigerants.
*Initial operation only has high pressure stage， and can run at full capacity in fast cooling speed and economical.
*Adopt two compressors and motors.In most condition， 380Vlow-voltage motor can meet requirement， which will assist to reduce cost.
*Adopt our generationⅢ screw compressor in mature technology and low maintenance costs
