Opis Air/water chiller with free-cooling, for outdoor installation. Suitable for summer air-conditioning for medium-sized services in residential and commercial buildings.
NRL_F is a water chiller fitted with a free water cooling system. This means the outdoor coil can be integrated with an additional water coil that exploits the low temperature of the outside air to cool the water returning from the system. In this way, the use of the compressors can be limited or even eliminated so the chilled water is practically free. The NRL free-cooling units are comprised of two R410a refrigerating circuits and one water circuit that by means of a three-way valve can activate the free-cooling water coil positioned in series with the plate evaporator. The hydraulic circuit can be fitted with an accumulation tank. The machine is also fitted with axial fans to ensure the quietest possible machine operation, and scroll compressors with a high yield and low electricity absorption. Low noise and high efficiency versions are also available.
