CHA Monoblock air-to-water heat pump 16/20, 20/24

The natural refrigerant R290 (propane) with a GWP of 0.02 allows higher flow temperatures, which makes it very well suited for existing buildings. 

Numerous technical details, such as a slow-rotating fan and the integration of components into a sound-absorbing EPP core, ensure low-noise operation.

The hydraulic connection can be made on the bottom or at the rear without additional accessories – depending on structural conditions and customer requirements. The conversion is implemented directly at the construction site within a very short time.

Integrated crane hook receivers support transport and handling. Additional practical accessories available such as prefabricated foundations, ready-made electrical subdistribution, hydraulic connection solutions and much more.

The appliance features a powder-coated housing and weather-resistant construction. The raised base is intended for installations in regions with higher snowfall levels.

The demand-controlled heating element with 9 kWprovides additional power and supports evaporator defrosting. For CHA-16/20 and 20/24, a version without electric heater is also available upon request.

Thanks to the WOLF Link home interface module (always included ex works), you can keep an eye on your customers' systems at all times via the Internet. Selected settings can be adjusted remotely via the Smartset portal.

Cascade systems with up to five units are available for larger heating applications. Modulating operation supports system performance across different load conditions.

Use excess electricity for heating, preparing hot water or even cooling in summer. A two-wire cable is all it takes to connect to the inverter with PV output. The system can be connected to compatible PV inverter systems.
