Main Parts

High-performance FM
It use outer rotor axial flow silent fan with five-leaf balanced aluminum alloy wind wheel. It has the advantages of corrosion resistance, large air volume and low noise.

Patent louvered casing

Tongyi’s patent louvered casing can better for waterproof,windproof and dust-proof. Patent no.:CN201030670236.9.

EEV,precise flow control
Wide working temperature range, faster and more accurate refrigerant flow control than capillary and mechanical expansion valve. Best choice to achieve higher efficiency and energy-saving.

World famous scoll compressor
world famous scroll compressor with low energy consumption and high energy efficiency output, which effectively shortens the heating water time and double extend the useful life of the unit.


Unique hyfrophilic fin coil heat exchanger,large amount for air inlet
Air exchangers(fin-coil)with hydrophilic coating are strongly anti-corrosive and perform at high efficiency.
