Air cooled chillers.
Nominal cooling capacity 266 ÷ 1383 kW.
The chillers of iPHOENIX G series, with low GWP refrigerant R513A, are the inverter solution for medium and large hydronic air conditioning systems (such as hospitals, offices, shopping centres, etc.), ensuring energy savings levels in accordance with ErP EcoDesign directive.
The installed screw compressors with variable-speed inverter technology are suitable to deliver the proper cooling capacity according to the request of the system, even in situations of high load variability.
The modular condensing section and the gradually management of the condensation pressure by the fans allowing to further increase the seasonal energy efficiency of the units.
