Technology
What are air-source heat pumps with natural refrigerant?
Air-source heat pumps for industrial and commercial use take most of the energy they need for heating, cooling and domestic hot water from the outdoor air. Enerblue units use propane (R290), a natural refrigerant, and reach energy class A+++.
The PALLADIUM ranges produce water up to 70 ºC with an ultra-low sound level and operate with outdoor air down to −20 ºC. The DWS version gives priority to DHW, and the 4P produces cooling and heating at the same time, with 4 pipes. The PURPLE HP and PURPLEi HP (inverter) cover 26 to 222 kW. The LITHIUM reaches 361 kW of heating capacity in a single unit.
