Commercial Brochure Refrigeration Units with Natural Refrigerant CO2 ELBA Release June 2022 REFRIGERATION UNITS ELBA Series Cooling capacities from 100 to 400kW in Medium Temperature, up to 600kW for industrial version Cooling capacities from 35 to 200kW in Low temperature, up to 300kW for industrial version Enex presents ELBA, the new range of transcritical CO2 refrigeration units, a synthesis of innovation, flexibility and energy saving. It is available in two dedicated versions: INDUSTRIAL and COMMERCIAL. Enex has been the first company ever to develop CO2 only solutions since 2004. CO2 (R744) is a natural fluid with zero OPD, GWP = 1. Neutral refrigerant by excellence, CO 2 is neither toxic nor flammable: among natural gases it is in fact the one with fewer contraindications so that represents the perfect choice for the future, not subject to the F-gas regulation on fluorinated gases.
