Commercial Brochure Air to water heat pumps with natural refrigerant CO2 AIRHEAT 2.0 Release June 2022 AIR TO WATER HEAT PUMPS Nominal heating capacity from 10 to 100 kW for domestic hot water production applications or process heating with high delta temperature, up to 90 °C Enex presents AIRHEAT 2.0, the new, renewed and extended range of air to water heat pumps for DHW (Domestic Hot Water) that uses CO2 (Carbon Dioxide - R744) natural refrigerant fluid. A synthesis of innovation, flexibility and energy saving, the AIRHEAT 2.0 series air to water heat pumps offer an unbeatable solution for the ability to produce large quantities of hot water at high temperatures, overcoming the typical limits of traditional heat pumps with synthetic refrigerants. 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.
