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.
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 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.
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.
Highly efficient fans cool freshly stored produce quickly and maintain an even refrigeration temperature throughout the interior.
The refrigeration components are safely integrated into the upper section where they can be easily accessed. For cleaning or servicing purposes, the compressor compartment cover can be easily opened on an upward hinge to guarantee excellent accessibility, so it possible to easily clean the filter on the condenser, which is positioned behind the unit compartment cover, without having to move the appliance.
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.
SwingLine
The stylishly contoured SwingLine design of these appliances makes them the number one choice if you are looking for impeccable design-tech specifications. With elegantly sweeping lines, these Liebherr appliances are a visually-appealing and stunning highlight in any professional environment. The SwingLine doors are ergonomically designed, easy to clean, and easy to open thanks to the full-length integrated grip handle.
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. This involves measuring the temperature at nine different points in the appliance interiors.
Reversible door hinges (left/right)
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.

The 5 metre long connection cable connects your professional Liebherr appliances with the SmartCoolingHub. It is ModBUS fitted and the 3 wire connection fits exactly into the connection plug’s RS 485 interface. If you connect multiple appliances to the SmartCoolingHub, you need an additional cable for each additional appliance.
With its 36 month licence for one cooling appliance, the SmartCoolingHub forms the basis for connecting with up to 20 professional Liebherr appliances. It is connected with the network and sends the appliance data to the Liebherr cloud. If the internet connection is interrupted, the buffer memory records all appliance data for up to 48 hours.
With the licence, you can use all basic functions of SmartMonitoring for a measuring point for 36 months. Create and send standard reports on the recorded temperatures and receive alarm notifications by e-mail. Access all appliance data and the basic functions using the dashboard and grant access to as many users as you like.
If there is an alarm, this additional function ensures you are notified by text message or phone call so you can react quickly. You can easily configure how you receive text message/phone call notifications using the dashboard. You can use the text message flat rate for 36 months following activation and you will be notified well in advance of the licence expiring.
To connect your professional Liebherr appliances with the SmartCoolingHub properly and reliably, you need the RS 485 connection plugs as well as the connection cable. An additional plug, which is attached to the connection cable, is needed for each additional appliance you want to connect to the SmartCoolingHub.
