● Highly efficiency semi-hermetic screw compressor

It can realize 4 steps or stepless capacity control. The unique squirrelcage compressor motor started up by Y-△ type can decrease start current by 33%, automatically cooled by the refrigerant.
 

● High efficiency air side heat exchanger

Unique M-shaped design, inner grooved & patent sawtooth design and hydrophilic aluminum fin guarantee efficient heat exchange between the air side exchanger and ambient air.
 

● Shell & tube heat exchanger

Dry type & tube heat exchanger with inner grooved copper tube optimizes the cooling & heating efficiency. Self-cleaning, high intensity, anti-shaking design and heat insulation covering material ensure shell & tube heat exchanger unstained, reliable, quiet, highly efficient.
 

●Complete protection

Water shortage protection, high/low voltage protection, anti-freezing protection, overload protection, overheat protection and oil level protection ensure high reliability and stability.
