version inverter
22-81 kW 52-91 kW
Chillers and heat pumps equipped with full inverter technology, integrating inverter compressors, electronic expansion valve, and variable-speed electronic fans for maximum energy savings and compliance with ErP 2021 regulations.
version euro
31-206 kW 52-170 kW
Chillers and heat pumps equipped with tandem or trio multi-scroll compressor technology to optimize energy savings and comply with ErP 2021 regulations.
Adaptation and Environment
- Reduced refrigerant charge with low-GWP R-454B, minimizing CO₂ footprint (77% less GWP than R-410A and 31% less than R-32).
- Available with plate heat exchangers or with shell-and-tube heat exchangers.
- Standard condensing pressure control for year-round operation.
- This range integrates compressors, hydraulic group, and built-in buffer tank within the air stream, offering a very compact version.
Energy Efficiency
- High efficiency at both partial and full loads, reducing operating costs in both the Euro version and the Inverter version.
- Partial and total heat recovery system from hot gases for domestic hot water (DHW).
- Water free cooling system for cost-free cooling (bodywork KWG-3).
