The Liebherr SFFfg 4001/740 explosion-proof laboratory freezer is ATEX classified (Ex II 3G) and suited to storing flammable substances in closed containers. Six drawers divide the 316 litres and it freezes 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.
Six drawers keep the contents separated, while glass shelves (five adjustable) offer an alternative layout. An acoustic door alarm reports an open door and a lock secures the contents. The key features:
