Commercial Brochure Refrigeration Units with natural refrigerant CO2 SENNA Release June 2022 REFRIGERATION UNITS SENNA Series Nominal cooling capacity from 70 to 380 kW in Medium Temperature Nominal cooling capacity from 4 to 110 kW in Low Temperature Enex presents SENNA, the new range of transcritical CO2 refrigeration units, designed to combine simplicity, compactness and high reliability. It is available in 8 sizes, each with a wide choice of compressor models: MINI, SMALL, TOP MAXI, PLUS, LARGE-200, LARGE-300 & LARGE-400. Sizes MINI to PLUS are only 850 mm wide, making them ideal for installation in plant rooms with restricted footprint and/or where access is through narrow doors. Enex was the first ever company to develop CO2 only solutions since 2004. CO2 is a natural fluid with zero OPD, GWP = 1. Neutral refrigerant of excellence, CO2 is neither toxic nor flammable: it is in fact the one of the natural gases with fewer contraindications and for this reason it is a candidate as the refrigerant of the future, not subject to the F-gas regulation on fluorinated gases.
