PRM and PRG. OUR SUSTAINABLE SOLUTIONS.

In recent years, the evolution in the use of refrigerants in heat pumps has required a constant commitment to research and development of more environmentally friendly solutions. The new F-Gas Regulation update now requires, in a phased manner by 2030, the use of low and ultra-low GWP refrigerants for all heat pumps.

The propane gas R290, the natural refrigerant par excellence, seems to meet these requirements perfectly. In addition, its use allows heat pumps to work better than those using traditional refrigerants, making the air-conditioning and DHW production system even more environmentally friendly, but it requires special precautions in its use to ensure maximum safety.

Aermec, which has always been at the forefront of environmental protection, wanted to anticipate the times required by the new regulation, designing and developing in its Design Centre and state-of-the-art Laboratories, the new PRM and PRG series reversible heat pumps.
Both series safely use the natural refrigerant R290 (propane) with ultra-low direct greenhouse effect (GWP = 3); the dual cooling circuit design allows for extremely low refrigerant content in each circuit (3.8 kg per circuit), which guarantees suitability for all applications according to EN378-1.
