The Polar Bear Series Oil-free Screw Piston Booster Compressor
Designed for severe cold regions
Internal water cooling circulating system without external cooling tower.Effectively avoid hard water quality and easy scaling in individual places.
*High efficiency circulating water pump;large flow design,improve cooling efficiency.
*Stainless steel circulating water case;Super large volume,without external piping.
*High efficiency cooling fan.Improve cooling efficiency ratio.

Fend against the severe cole
Design for adapt to severe cole area,Optional installation of antifreeze in sub-zero climate.Avoid to the cylinder or water circulation system frost crack caused by external cooling tower.
*Special lequip antifreeze,adapt the working condition below freezing point in northern winter.Can normal operate not below25℃

High efficiency and energy-conservation
Whole series standard equip rare earth permanent magnet frequency conversion motor,According to the fluctuation of gas to adjust power output.
*Permanent magnet screw and engine integrated,No coupling and other transmission links,higher efficiency.
*The efficiency of motor is 5% higher than that of ordinary motor,more energy conservation.
*Realize the configuration function of frequency,and wide range of frequency adjust.
