- Low GWP Refrigerant: they use R513A refrigerant, characterised by a low Global Warming Potential (GWP), in line with sustainability goals.
- Screw Compressors with Inverter: inverter technology allows precise and dynamic power regulation, adapting perfectly to variable heating and cooling loads and maximising energy efficiency.
- Simultaneous Production on 4 Pipes: ideal for buildings with simultaneous opposing loads, these units supply hot and chilled water simultaneously, simplifying the installation and replacing the need for separate boilers and chillers.
- Integrated Energy Recovery: the thermal energy that would normally be dissipated during chilled water production is recovered free of charge to produce hot water. This process greatly increases the overall efficiency of the system, turning what would be an energy loss into a gain.
- Structural and Economic Advantages: the multifunctional solution reduces the equipment footprint, simplifies the hydraulic circuit and allows for faster and cheaper installation and maintenance than conventional systems.
- Efficiency under Variable Loads: the operating logic ensures maximum energy efficiency even under variable heating and cooling loads, a typical condition in modern buildings.
