Targeted design

Internal water cooling circulaing syatem without external cooling tower.
Effectively avoid hard water quolity and easy scaling in individual places.

• High effciency 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 cold

Design for adapt to severe cold 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 equip antifreeze, adapt the working condition below freezing point in northern winter.can normal operate not below 25°C

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.
