CTC EcoAir 622M Air/Water Heat Pump

Description

CTC EcoAir 622M is a speed-controlled air/water heat pump with high capacity, specially developed for larger villas, apartment buildings and smaller commercial and industrial properties. The modulating inverter compressor continuously adapts the output between 4.5 and 22 kW to the property's current heating needs in real time. The stepless adjustment minimizes unnecessary start and stop cycles, which reduces mechanical wear, extends the service life and optimizes energy use so that heating costs can be reduced by up to 80%.

The heat pump efficiently extracts the renewable energy in the outdoor air and transfers it to gentle heat and abundant hot water without the need for boreholes or ground loops. With a robust design adapted to harsh Nordic winter conditions, the unit delivers full heating comfort down to minus 22 degrees and provides supply temperatures of up to 65 degrees. The sound-dampened scroll compressor and the aerodynamic design of the fan also ensure very quiet and vibration-free operation.

Reliable winter operation and functional design

To ensure trouble-free operation in winter, the outdoor unit is equipped with demand-controlled automatic defrosting that maximizes output and saves energy. Condensation water is drained away via an integrated condensation water tray with built-in heater as standard, which prevents ice formation under the heat pump. The durable casing made of galvanized and painted steel sheet protects against the elements for a long time to come.

Flexible docking options and smart control

For optimal function and the highest possible savings, the CTC EcoAir 622M is docked with a suitable indoor or control module:

• CTC EcoZenith i555 Pro: Highly recommended for extra large hot water needs with a hot water capacity of over 600 liters.
• CTC EcoZenith i360: Indoor module with integrated hot water preparation and a color touch screen that makes temperature control and adjustment intuitive and clear.
• CTC EcoLogic: Advanced control system that enables control and monitoring of existing boilers, external buffer tanks, free cooling or pool systems in up to four different heating systems. For exceptionally large energy needs, up to ten units can be operated together in cascade.
