Product features

• 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.

• ±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.

• 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.

• SmartMonitoring (optional)
The cloud-based digital solution continuously monitors and documents temperatures and alerts you immediately via email, text message or phone if any deviations occur

• 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.

• Easy to clean interior
The plastic inside container is made of polystyrene: a fully recyclable, robust, and odourless plastic. Manufactured seamlessly from one piece, it has no hidden dirt traps and the large corner radii can be cleaned quickly and easily. The perfect combination of sustainability and hygiene.

• Alarm relay
In the event of an alarm, the responsible control centre is informed immediately, usually through connection to the building control system. You can define in advance which alarms are to be forwarded, as well as set how long the forwarding remains active and whether a reminder should be sent after the alarm acknowledgement. This allows you to react immediately in critical situations.

• Replaceable door seal
Save time and money: Liebherr's plug-in door seals can be easily replaced. If a seal is damaged, you can replace it yourself without any tools.

• Mechanical lock
Liebherr professional appliances are equipped with a mechanical lock and two keys. This ensures that unauthorized persons cannot access your valuable and sensitive stored goods.

• Feedthrough for external sensors
To additionally control the storage temperature with the help of a separate sensor, wiring from the outside to the inside is required. The cable feeding offers a clean and professional solution here. The integrated opening allows connection without drilling holes or breaking the door seal.

• Min./max. temperature recording
Always keep an eye on the temperature: Min./max. temperature recording stores the minimum and maximum temperature values of the interior that have occurred from a defined start time and shows them clearly in the display. This way you can be sure that, up until the moment you read off the values, the storage temperatures were always within the tolerated limits.
