Plate heat exchanger (KWP)Shell and tube heat exchanger (KWB)
Partial and total heat recovery system from hot gases for domestic hot water (DHW).
Water Free Cooling System for Free CoolingAdaptation and Environment
- Reduced charge of low GWP refrigerant R-454B, minimizing the CO₂ footprint (-77% less GWP than R-410A and -31% less than R-32).
- Series condensing pressure control for year-round operation.
- Adaptability to the installation with a wide range of models.
- Maximum accessibility and easy maintenance through removable panels.
- 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 with AxiTop and electronic expansion valve as standard for minimal energy consumption.
- Units with a hydraulic group can incorporate high-performance electronic pumps.
