Environmentally friendly refrigerants

Optimised for maximum energy efficiency with natural, environmentally friendly refrigerant (R600a and R290). When combined with efficient compressors, these refrigerants deliver efficient operation coupled with low global warming potential (GWP).


Significantly reduces frost build-up on the interior of the freezer and on stored products, meaning defrosting is required less often. When necessary, defrosting is made easier by the smooth interior walls. The evaporator is embedded in the foam insulator to ensure high levels of energy efficiency and even cooling.

Robust, reliable and long-lasting top performer even when undertaking demanding work. With 10 years spare parts availability combined with high-quality materials and solid workmanship, Liebherr appliances are designed for a service life of 15 years. Manufactured in Europe to mimimise carbon footprint.
