Semi-hermetic, direct-drive, twin-screw compressor, low noise, low vibration, not easy to damage, long service life, a variety of volume ratios (compression ratio) of the precise design, can be realized in any working conditions, to avoid “over-compression” or “under-compression” brought about by the problem of excess power consumption. The design of the compressor is very accurate.
★High-efficiency spray-type (falling film) evaporator, the world's leading.
★Highly reliable differential pressure oil supply system, no oil pump, no energy consumption.
★Unique jet pump oil return system, can be completed without energy loss of the low-pressure side of the system back to the oil, back to the oil continuously, safe and reliable.
★Orifice plate throttling, stable performance, no moving parts.
★Stepless capacity adjustment, reasonably reduce operating costs.
★Can realize two-stage compression.
★Rational configuration of unique oil separator and flashing energy saver.
★Use of low-pressure booster technology - exclusive first.
