Water-to-water chillers and heat pumps
183-713 kW 201-806 kW
Adaptation and Environment
- High-performance units equipped with plate heat exchangers that allow for flexible configurations for centralized installations with closed water loops and geothermal systems.
- Reduced refrigerant charge with low-GWP R-454B, minimizing the CO₂ footprint (-77% lower GWP than R-410A and -31% lower than R-32).
- Available versions with hydraulic group.
- Water production up to 60ºC.
- Maximum accessibility and easy maintenance through removable panels.
Energy Efficiency
- High energy efficiency in both partial and full load, reducing operating costs.
- Tandem multiscroll for improved seasonal energy efficiency.
- Units available with inverter compressors as an option for maximum energy efficiency.
- Electronic expansion valve for minimum energy consumption.
- Units with a hydraulic group can incorporate high-efficiency electronic pumps.
