The SFFfg 5501 Performance freezer features static cooling and SmartFrost. The temperature is factory pre-set to -20 °C (set point range: -9 °C to -30 °C). Suitable for the safe storage of flammables and solvents (ATEX rated).

The Performance models are new additions to Liebherr’s Mediline Laboratory range and boast a new touch screen controller and built-in data logger alarm memory.


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