Product Description

Features of CO2(R744) Heat Pump:

1. The water can be heat up to 95ºC, high temperature output can reduce the volume of the storage tank and suitable for some specific usage (disinfection, cleaning)
2. Suitable for low ambient. Even in -43ºC, it can efficiently offer heat
3. Max COP is 5.5, our multi function model can reach max COP 7 (provide free cooling when producing heat)
4. Inverter control to offer various power accordingly to real requirement, save energy
5. Modules design, can reach higher Power by combined installation
6. 6 layers of pressure protection
7. Intelligent inverter control , can save 50% energy during defrosting
8. Smart wireless control, also RS485/Modbus central control
9. Programmable digital interface with touch keys
10. Monobloc design, no need extra work for high pressure refrigerant connection
