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
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.
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.
