CTC EcoAir 622M Air Source Heat Pump
The CTC EcoAir 622M is a heavy-duty, high-efficiency air-to-water outdoor heat pump featuring advanced inverter speed control. Specially engineered to handle larger residential properties, multi-family homes, or light commercial buildings, its intelligent compressor continuously self-regulates its power output between 4.5 and 22 kW to precisely match real-time heating demands. This continuous adjustment eliminates energy-wasting on/off cycles, reducing mechanical wear on core components and lowering utility bills.
Built to withstand severe winter conditions, the outdoor unit delivers flow temperatures up to 65 °C while operating efficiently down to outdoor temperatures of -22 °C. It features a demand-controlled automatic defrost cycle that removes ice from the evaporator with minimal runtime interruptions. A built-in condensation tray equipped with an integrated heating element comes as standard to ensure reliable, ice-free drainage during freezing weather. Despite its high capacity, the unit runs exceptionally quietly thanks to a sound-insulated scroll compressor and an aerodynamically optimized fan.
