pump LH series

The top class components ensure the system reliability.

Additional oil-feeding device will inject preheated lubricant to compressor before it starts until the system pressure is built, to avoid the metal contact of rotors.

Using electronic expansion valve, to increase the cooling speed and partial load efficiency, the changes flow of refrigerant when it is necessary to adjust the suction superheat precisely.

PLC controller makes system highly intellectualize, can operate automatically loading / unloading according to the temperature, diagnosis by itself.

With ECO optional, become a cooling cycle, highly improve capacity and COP, more effective due to high cooling temperature and low evaporating pressure.

New screw compressor design, high efficiency, energy-saving, longer life, adapt to various loading condition, resistant to liquid impact, no compressed volume loss, cooling efficiency is higher than piston compressor at low temperature condition.
