Product Description

WSH is a water-condensed heat pump that works with R134a refrigerant. It’s a single-circuit or dual-circuit unit for indoor installation, with independent control of the individual circuits, high-efficiency twin-screw compressors with continuous modulation (40% – 100% if fitted with a standard thermostatic valve, or 25% – 100% with an electronic valve). The machine is reversible on the cooling side, thanks to a cycle inversion valve. It has high-efficiency plate heat exchangers on the system side and source side. Free hot water can also be produced in units with a desuperheater. The “Always Working” function ensures continuous machine operation, even in critical conditions: the machine is able to self-adjust, so it never stops. Available in standard and low noise versions.
