    Description

    R744 heat pump absorbs heat from the air through natural refrigerant (CO2), providing an important, cost-effective and timely solution for domestic and commercial hot water systems.


    The maximum outlet temperature of the CO2 heat pump reaches 95°C-120°C. And it can work normally at -20℃---25℃.


    Features:

    1. High efficiency and energy saving

    Heat pumps work by absorbing and moving heat from the surrounding area, consuming only a quarter of the cost of traditional electric heaters, saving users a significant amount of electricity bills.

    2. Green and environmental protection

    By using a natural refrigerant (CO 2 ), increasingly stringent decarbonization and environmental protection initiatives across the country can be easily met.

    3. Available 24/7

    All-weather operation: stable operation, not affected by any wind, rain and snow.

    4. Durable

    Heat pump brand components such as Copeland compressors, Danfoss electronic expansion valves, Eaton AC contactors and thermal relays guarantee high quality and long life.

    5. Automatic defrost

    Provides an advanced defrost cycle with energized coils, eliminating the need to reverse defrost operation.

    6. Intelligent operation

    Digital LED display, can connect to Wi-Fi. Remote APP can monitor unit status in real time, record operating data, check faults, and change set points and operating modes.

    7. Higher capacity

    CO2 heat pumps can provide higher capacity and take up less space, easy to install

    8. Widely used

    Designed for new and retrofit multifamily and gyms, as well as industrial, hospitality, education, and healthcare applications.
