NRP is a multifunction unit charged with R410a gas for the simultaneous but independent production of hot and cold water. The 2-pipe units are designed for applications where cold/hot water and domestic hot water is required throughout the year. The 4-pipe units are designed for systems where hot and cold water may be requested simultaneously. The machine is fitted with axial fans with reduced sound emissions, and scroll compressors with a high yield and low electricity absorption. The NRP has 3 heat exchangers: one on the environment side (finned pack copper/aluminium) and 2 indoor (plate). NRP is ideal for small/medium-sized services in residential, commercial and industrial contexts. There are 3 versions – standard, low noise and high efficiency.
