Compressor

The dependable flexible

compressor, with optimized

R410a system, can achieve high

water temperature up to 60DegC,

while ensures long life of the

compressor.

4-Way valve

The reliable 4 way valve can

avoid gas mixing, and ensure

stable defrosting.

Condenser

The Tube in shell heat exchanger as

condenser, with bigger heat

exchanging area and higher

efficiency.

Thermal expansion valve

The 2 way thermostatic expansion

valve ensures high efficiency when

heating, moreover, ensures high

efficiency when defrosting.

Evaporator

The hydrophilic fin-tube heat

exchanger has big heat exchanging

area and rational fin distance, thus

significantly improves heating and

defrosting efficiency.

Fan

The exterior motor fan, with 5 fan

blades, is strictly balanced. The 5

fan blades run slower, and make

sure high air volume, thus largely

brings down the noise.
