Alongside the PRM air cooled reversible modular heat pump, Aermec has also launched the PRG reversible air/water heat pump. Both units feature the natural refrigerant R290 which offers an ultra-low Global Warming Potential (GWP).

Designed to meet the requirements for commercial buildings and industrial applications, the PRM’s cooling capacity is 95.6kW with a heating capacity of 101.7kW. Hot water can be provided up to 75ºC.

The modular design of the PRM allows for up to nine units to be coupled together, reducing the overall unit dimensions to a minimum providing flexibility to the designer and future expansion/upgrade of the system. Modularity also provides the user with redundancy and reduced system down time.

Designed for industrial or commercial building applications the PRG reversible air/water heat pump offers a cooling capacity of 49.9kW to 146.9kW and a heating capacity of 51.7kW to a maximum of 144.3kW.

The design of the unit provides the designer with a wide operating range, from as low as -20ºC outside air temperature in winter, up to 48ºC in summer, with hot water being produced up to 75ºC.

“The market for propane products is continually growing,” says David Evans, Aermec’s national sales manager. “This is being driven by demand for more eco-friendly refrigerants with ultra low GWP’s but also as a result of changing global legislation. Propane offers us and designers a challenge with how we apply it to buildings. It is now part of our role to educate the market.”

Propane units offer an attractive proposition thanks to their ability to provide higher output temperatures, R290 is a natural refrigerant and often less charge is required, there’s no glide temperature difference and wider delta temperatures. Depending on the application, units can be retrofitted into existing systems.
