Liebherr refrigerator for laboratories and research

Constant temperatures are essential when storing sensitive substances. This especially applies to work in laboratories, where even the slightest deviations can jeopardise the quality of research results. This is why Liebherr has developed new refrigerators and freezers specifically for this sector, combining maximum refrigeration performance with optimum temperature stability. Innovative safety features with monitoring and alarm functions offer all-round protection from all kinds of incident and malfunction. The next generation of appliances also set new standards in terms of energy efficiency and total cost of ownership. On the next few pages we present the latest results of research and development by the refrigeration specialists at Liebherr and show how they can benefit safety in your laboratory.

Product features

• Min./max. temperature log
The min./max. temperature log stores the minimum and maximum interior temperatures and shows on the display whether the storage temperatures were within the tolerance limits.

• +2 °C SafetyDevice
If the temperature falls below +2 °C due to a malfunction, the SafetyDevice takes control, stabilising the temperature, activating the alarm and protecting the contents from freezing

• Power failure alarm
When mains power return the device gives a visual and audible warning signal.

• LightAlarm
In the event of an uncontrolled temperature rise or other problems, the interior light of the appliance starts flashing. This visually shows when action is needed.

• Feedthrough for external sensors
An integrated opening allows a separate sensor to be connected for additional temperature monitoring without having to drill holes or break the door seal.
• Mechanical lock
Liebherr professional appliances are equipped with a mechanical lock and two keys. This ensures that unauthorised persons cannot access your valuable and sensitive stored goods.

• 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.

• WiFi/LAN interface (optional)
The WiFi/LAN interface enables you to easily connect your appliances with Liebherr SmartMonitoring or existing local systems.

• Easy-to-clean interior
The inner liner made of fully recyclable, robust and odourless polystyrene is manufactured in one piece without joints. This makes it quick and easy to clean the large, rounded corners.
