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.
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.
Explosion protection: ATEX 95
The Atex 95 certification certifies that Liebherr laboratory refrigerators and freezers with explosion protection as defined by EU Directive 94/9/EC (ATEX) are suitable for storing explosive and highly flammable materials.
Forced air cooling
Highly efficient fans cool freshly stored produce quickly and maintain an even refrigeration temperature throughout the interior.
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.
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.
Refrigerants R600a and R290 are environmentally friendly – they have a minimal greenhouse effect and no ozone depletion potential – and therefore, they have almost completely replaced those previously used (R134a and R404a). All Liebherr impulse sales chest freezers use R600a or R290 as refrigerants and offer outstanding energy efficiency, which improves their CO2 footprint and promotes sustainability.
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.
