This concept will be perfect for retrofitting your installation to low temperature R22. CO2 can be used to cool products or the air in industrial premises down to -50 ° C. Optimal energy efficiency : The combination of two “cascade” compression cycles allows each of the compressors to operate at reasonable compression ratios to obtain optimum energy efficiency. Hygiene and safety guaranteed: CO2 is a non-toxic, non-flammable, food-grade fluid: also, its contact with food products does not make them unfit for consumption. Reduction in installation costs due to its thermophysical and thermodynamic properties, the CO2 flow rate is lower and the compressor to be installed is small compared to an HFC type refrigerant. Safety and environmental protection : the quantity of HFC refrigerant is limited to the high pressure stage of the cascade. Various applications : AXIMA REFRIGERATIONhas already produced numerous installations using this technology for cold stores for frozen products, freeze-drying of coffee, the seafood processing industry, etc. The use of CO2 in cascade on negative cold is now tending to increase. impose as a standard in Agribusiness, GMS and logistics. > Cascade NH3 / CO2 brochure > Cascade R134A / CO2 brochure GDF SUEZ Group sites www.gdfsuez.com Legal Notice Documentation Sitemap Contact (+33) 3 88 19 19 00 Energy is our future, let's save it !
