Multipurpose air cooled units with axial fans
NRP
R410A
NRP is the range of multipurpose external units operating on refrigerant R410A, designed for 2 or 4-pipe systems. With just one unit simultane- ous and independent requests for hot and chilled water can be accommodated all year round.
Range:
• Refrigerant R410A.
• 2 refrigerant circuits.
• High efficiency even at part load.
• Heat exchangers optimised to benefit from the excellent heat transfer characteristics of R410A.
• High efficiency scroll compressors.
• Axial fans with low sound level.
• Extremely solid structure with anti-corrosion polyester paint.
• Extended operating limits in heat pump oper- ation:
- Maximum leaving water temperature 55 °C.
- External air temperature from -15 °C to 42 °C.
• Units fitted as standard with fan speed con- troller (DCPX), which permits operation in the winter with external temperatures down to –10 °C, and in heating mode with external temperatures up to 42 °C.
• Available versions:
- “A” High efficiency heat pump.
- “E” High efficiency silenced heat pump.
• Ventilation Unit:
- “°” Standard.
- “J” Inverter.
• Options for integrated hydronic modules with pumps, water filter, flow switch, expansion tank.
• Microprocessor controls.
