Air-to-water heat pumps for mild | moderate climates
121-583 kW 130-648 kW
Plate heat exchanger (KWP-C)
Shell and tube exchanger (KWP-M)
Partial heat recovery system from hot gases for domestic hot water (DHW)
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 hydraulic group and built-in buffer tank to reduce the frequency of compressor stops and starts.
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.
