• Retrofitting SmartMonitoring Liebherr SmartMonitoring offers a comprehensive solution for documenting and monitoring measurement and operating data, alarm messages and appliance statuses. To connect the SmartCoolingHub required for this purpose to this appliance, you will need the RS 485 interface converter, which is available separately. • 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. • 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 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 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.
