±5 °C temperature stability

Sensitive substances cannot be subjected to large deviations from the set storage temperature. Liebherr freezers guarantee a minimal temperature fluctuation of no more than ±5 °C. This means that your valuable contents are optimally protected against impairment and their quality is preserved.

Compliance with the ATEX Directive

Liebherr laboratory equipment conforms to EN/IEC 60079-0 or EN-IEC 60079-7 and complies with EU Directive 2014/34/EU (“ATEX Directive”). Classification of the interior to <Ex> II 3 G Ex ec IIC T6 (declared as Zone 22) makes them suitable for flammable substances in closed containers that could form explosive atmospheres.

SmartFrost

SmartFrost reduces frost build-up in the interior and on stored products. Defrosting is required less often – and when it is necessary, it is made much easier by the smooth, easy-to-clean interior walls. The evaporator in the foam insulation ensures high levels of energy efficiency as well as even cooling.

Retrofittable WiFi/LAN interface

This is how easy it is to network a Liebherr: With the retrofittable WiFi and LAN interface, appliances can be effortlessly connected to external systems, such as SmartMonitoring from Liebherr. With the digital monitoring solution, the storage temperature is controlled and documented conveniently and securely via the subsequently set up interface.

Mechanical lock

All professional Liebherr appliances are equipped with a mechanical lock with two keys for the storage of temperature-sensitive products. This way you can be sure that no unauthorised hands can access your stored goods.

Designed for a service life of 15 years

Sustainable means the appliance is not only economical, but also durable. High-quality materials and solid workmanship, coupled with at least ten years of spare parts availability, make a Liebherr appliance a robust, reliable, and extremely long-lasting top performer in demanding everyday work.
