Cooling capacity: 262 ÷ 1249 kW
Air/water inverter chiller for outdoor installation. Suitable for air-conditioning and the production of hot water for large-sized services in residential, commercial and industrial buildings.
NSI is a chiller with 1, 2 or 3 circuits charged with R134a gas. It has axial fans to ensure the quietest possible machine operation, the latest inverter twin-screw compressors, a tube bundle heat exchanger and finned pack copper/aluminium coils. The unit with several refrigerant circuits is designed to provide the maximum yield when fully charged, but also guaranteeing excellent efficiency even with partial charging and ensuring continuity if one circuit or more stops operating. The machine cools water to supply the distribution system that is usually connected to fan coil type terminals. In addition, NSI can also produce domestic hot water if it is fitted with a desuperheater or total recovery system, so it’s ideal for residential, commercial and industrial contexts. There are 2 versions – standard and high efficiency.
