KK Air to Water Heat Pump

PHNIX Air to Water Heat Pump KK Series can keep your home temperature constant with their steady running performance. With excellent efficiency, the units can also bring you a warmer house with lower installation cost and less space requirements.

Patented Efficient Heat Exchanger

The patented high efficiency heat exchangers have a strong counter current design, and are helpful for refrigerant super-cooling. Because the interspace between the shell and tubes is small, this leads to a larger flow, which makes oil return easy. Additionally, the large tube diameter prevents tubes from deposits and blocking.

The compressors can be on or off according to the actual energy need. So the units are reliable and easy to control.

air to water heat pump exchangers

Air exchangers (fins-coil) with hydrophilic coating are strongly anti-corrosive and perform at high efficiency.


With strong countercurrent design, the patented C&S heat exchanger is conducive to improving the efficiency and reliability of the unit.
