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.
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.
Premium-quality lid seal
Uniform closure of the freezer is guaranteed thanks to the flexible lid seal. It prevents cold air escaping from the appliance and so enhances its energy efficiency. The seal is made from a highly resilient, long-lasting material and its performance is unaffected by temperature fluctuations. It is easy to clean and extremely hygienic.
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 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
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.
