Aermec presents NPG, the new series of multi-purpose air-water units with eco-friendly gas R32, suitable for outdoor installation, designed to produce hot water and chilled water simultaneously and independently. NPG is available for both 2-pipe and 4-pipe systems, to meet different plant needs:
- the 2-pipe version, ideal for all those applications (e.g. hotels) that, throughout the year, require the production of chilled water or hot water at the same time as the production of domestic hot water
- the 4-pipe version, ideal for all those applications (e.g. offices/structures with large windows) where the simultaneous production of chilled and hot water is required, as an alternative to the chiller/boiler system, or to avoid continuous switching of a traditional heat pump
It guarantees continuity of operation down to -15°C of outside air in winter, and up to 49°C in summer, while the maximum hot water temperature is 60.0°C. The multifunction unit is double cycle, with tandem or trio configuration of scroll compressors, guaranteeing both greater efficiency at partial loads, with excellent SEER values in accordance with the requirements of European Regulation 2281/2016, and greater continuity of operation even in case of maintenance of one of the circuits.
The unit is equipped with 3 heat exchangers: the copper-aluminium finned pack room side heat exchanger, and 2 internal plate heat exchangers. Aermec NPG series has been designed for residential, commercial and industrial use.
The power range is wide, with cooling capacity from 207 to 956 kW and heating capacity from 212 to 671 kW. It is available in silenced and high-efficiency version.
