As a leading exporter of CO2 heat pump systems, we provide efficient, environmentally friendly heating and cooling solutions for a variety of applications worldwide.
Our CO2 heat pump systems have a wide range of applications. They excel in residential heating, especially in colder regions where efficiency gains are significant. In the commercial sector, they are ideal for supermarkets and facilities requiring continuous cooling and heating. Industrial applications include high-temperature processes and space heating in harsh environments.
Features
1. Water can be heated up to 90°C. High-temperature output reduces the size of the water storage tank, making it suitable for certain applications (disinfection, cleaning).
2. Suitable for low-temperature environments. Effectively provides heat even in -43°C environments.
3. Maximum COP of 5.5, with our versatile models reaching a maximum COP of 7 (providing free cooling while generating heat).
4. Inverter control provides variable power according to actual needs, saving energy.
5. Modular design allows for higher power output through combined installation.
6. Six levels of pressure protection.
7. Intelligent variable frequency control, achieving 50% energy savings during defrost.
8. Intelligent wireless control, also available via RS485/Modbus central control.
9. Programmable digital interface with touch keys.
10. Integrated design, eliminating the need for additional high-pressure refrigerant connections.
