Commercial Brochure Refrigeration Units with Natural Refrigerant CO2 NEVA Release June 2022 REFRIGERATION UNITS NEVA Series Cooling capacities from 15 to 110 kW in Medium Temperature Cooling capacities from 10 to 53 kW in Low Temperature Enex presents NEVA, refrigeration units characterized by high efficiency and ease of use, specifically designed for medium-large supermarkets and in the Ho.Re.Ca. sector. Among the variety of this range, in addition to the models for medium temperature only, there are booster models that provide both medium and low temperature. Also NEVA, like the other ranges, uses the natural CO2 refrigerant - carbon dioxide - and therefore can be used without any legislative limitation and without the uncertainties and disadvantages associated with the use of synthetic refrigerants. 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.
