Product Description

Features of CO2(R744) Heat Pump:

1. The water can be heat up to 90C, 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 -43C, 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

The advantages of CO2 as a refrigerant

• Climate-neutral environmentally friendly refrigerant R744 (CO2)
• Without environmentally hazardous decomposition products
• No additional contribution to the greenhouse effect (GWP = 1)
• Does not contribute to the ozone depletion (ODP = 0)
• No disposal and recycling requirements
• No availability constraints
• Low security requirements - Safety Group A1
• Non-toxic, non-flammable, thermally stable, compatible with other material
