New heat pumps "RHOSS" POKER290

After introducing a full product catalog with A2L refrigerants, Rhoss introduces a new line with the natural refrigerant R290:

POKER290, high-temperature, low-GWP reversible heat pumps with scroll compressors. The new range is available in one size, which can be combined with up to 4 units via the new integrated SDR sequencer, covering capacities from approximately 48 to 190 kW.

Natural gas, F-norms not required. Ideal for new carbon-free systems or to replace traditional boilers.

With the introduction of this new product, it is now possible to offer fluorine-free refrigeration units for new installations as well as for building renovations with the integration or complete replacement of the existing heating system, including gas boilers.
