- R1234ze refrigerant
NSG is an air-cooled outdoor chiller designed to meet air conditioning needs in residential/commercial complexes or industrial applications. It is equipped with screw compressors in order to use the new HFO R1234ze gas with ODP = 0 and GWP (Global Warming Potential) = 7. These units have multi-circuits to ensure maximum efficiency at full load and partial loads alike, as well as to ensure continuity of service if one of the circuits fails. The entire range uses aluminium micro-channel condenser coils that use less gas than traditional copper coils. Several versions, even silenced models, can be selected, all of which ensure high levels of EER efficiency in Class A in accordance with the Eurovent standard.
