The Liebherr SFFfg 5501 explosion-proof laboratory freezer is ATEX classified (Ex II 3G) and suited to storing flammable substances in closed containers. It freezes 499 litres from -9 °C to -30 °C. This serves demanding applications in the pharmaceutical industry and the food industry.
The ATEX classification makes the unit suitable for an explosion-proof setup. SmartFrost limits ice build-up, so you defrost less often. Minimum and maximum temperatures are recorded continuously and remain readable for up to 42 days, also via an app. As a result, you demonstrate the storage conditions verifiably.
Five shelves divide the 499 litres and the self-closing door latches by itself. A lock secures the contents and two levelling feet set the unit level. An optional swing-castor set makes the unit mobile. The key features:
