Specifications
WFG is a heat pump with reversible water side that works with R1234ze refrigerant. It’s a dual-circuit unit for indoor installation, with independent control of the individual circuits. Optimised for low condensation temperatures, it’s ideal for cooling-only applications that use water from a well or cooling tower as their source. Fitted with high-efficiency twin-screw compressors with continuous modulation (12.5% – 100% for each compressor), an electronic thermostatic valve as standard, and tube bundle heat exchangers (system side and source side) optimised for R1234ze gas. Free hot water can also be produced in units with a desuperheater or total recovery system. The “Always Working” function ensures continuous machine operation, even in critical conditions: the machine is able to self-adjust, so it never stops. Standard and high efficiency versions (also low noise) are available.
