NSM_B 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. Thanks to an intermediate plate heat exchanger, it's not necessary to add glycol to the water on the system side, but only to the water on the free-cooling coil side (hence the term "glycol-free"). The NSM B glycol-free units have 2 or 3 refrigerant circuits using R134a and one hydraulic circuit that, by means of a three-way valve, can activate the free-cooling water coil positioned in series with the shell and tube evaporator. The hydraulic circuit can be fitted with an accumulation tank. The machine is also fitted with axial fans and twin-screw compressors.
