HWS_E is a single-circuit or dual-circuit condenserless unit charged with R410a refrigerant gas. It’s designed for indoor installation and guarantees easy access to all the internal components. Fitted with twin-screw compressors with a high yield and low electricity absorption, and an evaporative heat exchanger with braze-welded steel plates to cool the water. As the machine has no condenser, shut-off taps are used to keep all the refrigerant liquid inside the unit for purposes of extraordinary maintenance (when necessary). In any case, the machine is consigned with a seal gas charge only. Particularly suitable for medium/large-sized applications, it’s ideal for residential and commercial contexts (cooling only).
