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.
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 proof: 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).
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
Appliances can be connected to an external monitoring system using the serial bus interface. If there is no monitoring system for connection via the interface, an interface converter retrofit kit is available as an optional accessory. This enables a connection to be made to a PC or a laptop. The bus interface allows up to 20 appliances to be connected in series and networked together. Temperature and alarm can therefore be documented and archived, e.g. via SmartMonitoring.
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.
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.
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.
