Air to Water Heat Pump – A2 & B Series

Products features and advantages:

1. DHW and house heating function, cooling is optional in B series

2. Use eco-friendly refrigerant R410A;

3. Use bigger heat exchanger with higher efficiency – COP exceeds 4.0 at Air 7℃ /Water35℃;

* Use famous components, like Japanese brand compressor, Emerson ALCO expansion valve, Siemens electric, etc., high quality and reliability
* Emerson expansion valve keeps the most suitable refrigerant flow in any case.
* SWEP stainless steel plate heat exchanger, 100% stainless water circuit

4.  Intelligent microprocessor control with heating curve, which is especially good for house heating and can reduce electricity consumption furthermore. 

5. Perfect protection design such as anti-frost protection, high/ low pressure protection, water flow protection, high-temp protection, etc., and automatic defrost function, assuring the system to run safely and efficiently even in hard conditions

6. Electric protection class IPX4

7. CE-RoHS certification by TUV
