Pre-equipped SmartMonitoring

Pre-equipped SmartMonitoring

Liebherr SmartMonitoring offers a comprehensive solution for documenting and monitoring measurement and operating data, alarm messages and appliance statuses. The SmartCoolingHub required for this can be connected directly to this appliance via the pre-equipped RS 485 interface.

Alarm test function

Alarm test function

This test function can be used to check whether an internally or externally connected alarm system is functioning correctly. The appliance’s refrigeration performance is not affected by this test.

Explosion protection: ATEX 95

Explosion protection: ATEX 95

The Atex 95 certification confirms that Liebherr laboratory fridges and freezers with explosion protection are appropriate for the storage of explosive and highly flammable materials within the meaning of EU Directive 2014/34/EU (ATEX).

Digital temperature display

Digital temperature display

The digital temperature display indicates the refrigerator’s interior temperature to the exact degree. This can be easily read from the outside to give users immediate information and without the need to open the appliance.

Forced air cooling

Forced air cooling

Highly efficient fans cool freshly stored produce quickly and maintain an even refrigeration temperature throughout the interior.

Efficient refrigeration system

Efficient refrigeration system

Liebherr guarantees the outstanding quality of its refrigeration systems through expertise derived from decades of experience in the refrigeration technology sector, and through continuous research and development. By employing only premium-quality compressors, condensers, evaporators and other refrigeration components the energy consumption and operating costs of Liebherr appliances are significantly reduced.

Serial bus interface

Serial bus interface

A serial bus interface can be used to connect appliances to an external monitoring system. If there is no monitoring system that can be connected via the interface available, an interface converter retrofitting kit (which connects with a PC or laptop) can be obtained as an optional accessory. The bus interface can be used to serially connect and network up to 20 appliances. Temperature and alarm details can be documented and archived using Liebherr's Temperature Monitoring software.

Temperature alarm

Temperature alarm

The integrated temperature alarm indicates if the lower or upper alarm thresholds have been breached. It uses both acoustic and visual signals to provide maximum security for goods that have been stored.

Temperature stability and consistency EN 60068-3

Temperature stability and consistency EN 60068-3

All laboratory refrigerators and freezers are tested at the state-of-the-art Liebherr development facilities according to procedure EN 60068-3 for measuring temperature stability. This involves measuring the temperature at nine different points in the appliance interiors.

Environmentally friendly refrigerants

Environmentally friendly refrigerants

Liebherr appliances are optimised for maximum energy efficiency and low operating costs. We only use the natural and environmentally-friendly refrigerants R 600a and R 290. When used with highly efficient compressors, these are extraordinarily efficient and, with their low global warming potential, also future-proof.

Reversible door hinges (left/right)

Reversible door hinges (left/right)

Liebherr appliances are factory-fitted with door hinges on the right. The ability to change the hinge side allows the appliance to be tailored to individual requirements and optimally positioned.
