Air-to-water heat pumps for cold climates
227-583 kW 238-631 kW
Wide operating range with high efficiency and extended operating limits, functioning down to -15ºC outdoor temperature at full load.
Partial heat recovery systems to support domestic hot water (DHW) production.
Water Free Cooling System for Free CoolingAdaptation and Environment
- Reduced refrigerant charge with low GWP R-454B, minimizing the CO₂ footprint (77% lower GWP than R-410A and 31% lower than R-32).
- Series condensing pressure control for year-round operation.
- Adaptability to the installation with a wide range of models.
- Versions with a hydraulic group and integrated buffer tank to reduce the frequency of compressor start-ups and shutdowns.
Energy Efficiency
- High energy efficiency at partial and full loads, reducing operating costs.
- Tandem multiscroll for improved seasonal energy efficiency.
- Electronic fans and electronic expansion valve as standard for minimal energy consumption.
- Units with a hydraulic group can incorporate high-performance electronic pumps.
