01 Semi-hermetic Compressors
▪ Adopted world famous branded semi-hermetic compressors for long term reliable and efficient running; ▪ Compressor runs with no stage limits to realize stageless continuous adjustment of cooling capacity in between 25%-100% power loaded and maintaining stable outputs; ▪ Option: HANBELL, BITZER
Shell and tube condenser adopts high-precision external treaded copper design and shell and tube type evaporator adopts inner treaded copper design, with larger heat exchanging area for higher efficiency and maximizing system performance.
03 Frequency Conversion Control System
▪ Advantage of frequency conversion, the soft start of chiller can reduce impact of the starting current, built-in DC reactor can minimize the harmonic interference;
▪ High efficiency and energy saving, with world-class airborne variable frequency driving technology, which greatly improves energy efficiency of the unit, and the highest integrated part load performance coefficient (IPLV) could reach about 10;
04 PLC Controller
▪ Adopted the latest generation PLC controller to realize precision control of the unit, ensuring efficient and stable running; ▪ Accuracy of outlet chilled water temperature within ±0.5 Celsius degrees; ▪ Equipped with one week 24 hours timing function to enable automatic operation by appointment; ▪ Equipped with RS485 communication function to realize automatic remote management.
05 Aviation Hose
Instead of capillary copper tube, it is resistant to high temperature and high pressure, and will not cause refrigerant leakage due to excessive pressure.
