Heat Pump R744

Heat pump r744 is a perfect boiler alternative solution. Our heat pumps are easy to install and compatible with all standard radiators and heating systems.

The compressor of the CO2 heat pump uses R744 refrigerant, which is carbon dioxide (CO2). It is an all-natural, non-polluting, non-toxic refrigerant.

Although today’s best heat pumps can operate at outdoor temperatures ranging from -20 °C to -25 °C, the R744 models equipped with compressors can operate trouble-free at outdoor temperatures as low as -30 °C to -35 °C , The temperature of the hot water produced exceeds 90 degrees Celsius!

The R744 heat pump has high efficiency and low carbon emissions, making it an ideal choice for home and commercial applications.

Heat Pump R744 Features:

1). The reliability and outstanding performance of the world-renowned scroll compressor

2). Natural CO2 (R744, carbon dioxide) refrigerant. Its ODP is 0, GWP is 1, and it is non-polluting, non-toxic and non-flammable to the environment

3). Intelligent control: microprocessor digital controller with liquid crystal display

4). Adjustable water temperature: 25℃-90℃. There is no potential risk of contaminating drinking water

5). Can produce high temperature hot water at -20℃ outdoors

6). Blue hydrophilic aluminum fins, anti-corrosion, durable, low maintenance

7). Internally threaded copper tube, higher efficiency

8). The four-way valve ensures reliable defrosting function

9). Alco or Danfoss thermal expansion valve can more accurately control the pressure and temperature to ensure anti-fatigue and extend the service life.

10) Can be used for floor heating, fan coils, water heaters and modern radiators

Warranty:

1). Passed CE and RoHS certification

2). Service life is about 20 years

3). 2 years warranty, buy with confidence

Heat Pump Components:

1. Silver welding

Silver welding technology makes the unit system more reliable; it is likely to avoid refrigerant leakage

2. Intelligent control

The unit adopts an intelligent control system: microprocessor digital controller, liquid crystal display

3. Shell and tube

Heat Exchanger High-efficiency shell-and-tube water heat exchanger, the highest working water pressure can reach 3.2Mpa

3. Reliability of Alco thermal expansion valve

4. Efficient and environmentally friendly refrigerant, does not destroy the ozone layer

5. Low noise fan

Axial fan is adopted, with large air volume and low operating noise

6. Air pressure drive water flow control valve

The water flow is controlled by the pressure of the refrigerant to ensure that the hot water supply can be adjusted at a constant temperature
