After an intensive field trial phase, this technology was launched in 2009 as the CO2OLtec® refrigeration system. Today, CO2OLtec solutions are used to keep food fresh in thousands of European supermarkets and hypermarkets while reducing their carbon footprints by approximately 50 percent compared to systems using the synthetic refrigerant R404A. CO2OLtec Integral solutions enable a store to save up to 35 percent in energy costs by leveraging the waste heat from its refrigeration system to heat the building and its sanitary water. Carrier’s advanced CO2OLtec Evo transcritical CO2 systems feature newly developed adjustable modulating ejector technology. This new technology increases system energy efficiency, making CO2 systems a viable alternative in warmer climates as well as providing heat reclaim advantages in colder and milder climates.
