Superior energy efficiency and cutting-edge technology: from today, Criocabin respects the Montreal protocol to reduce the use of substances responsible for the greenhouse effect. R290 gas is the natural alternative to HFC refrigerants and with a high GWP coefficient. It is non-toxic and has first-class thermodynamic and energy efficiency properties. From 2018 all the built-in refrigerator units of Criocabin adopt R290 gas.
