Features: 
 ■ save energy, reduce costs and achieve 0 to 100% of the continuous cooling capacity automatically adjust automatically adapt to changes in temperature and heat load and automatically adjust the cooling capacity, eliminating line pressure loss, maintain optimal compression, to ensure optimum operation unit efficiency. 
 ■ small cooling capacity allows long-term operation, ability to adapt to changes in ambient temperature, stability and reliable control, soft start / soft stop, start, power is not greater than the motor rated current, start and stop when the total elimination of the degree of electrical shock. Start acceleration and parking the speed can be adjusted freely. 
 ■ start and stop when the complete elimination of mechanical shock and reduce wear of bearings and other equipment, reduce maintenance costs. 
 ■ There are over voltage / over current / voltage / overload / earth / phase loss protection function improved. Start-stop / failure status, timely and effective door control. Shutoff / Ultra-pressure / oil temperature anomalies / over-current faults and all timely and effective protection of the signal. 
 ■ LED digital display to set the cooling water temperature and the actual temperature of chilled water, chilled water through the buttons free to adjust the set temperature, stable performance, reliable, customers choose the best products.
