Liebherr low temperature freezers

Liebherr low-temperature (ULT) cabinets set the standard in the temperature range from -40 °C to -86 °C: In terms of safety, performance and operating comfort, they offer everything to meet the high requirements of laboratories and scientific institutions. Take advantage of low operating costs, stable cooling, large capacity with practical features and numerous safety functions for low-temperature cabinets. Trust our years of experience as a cooling and freezing specialist.

Emergency messages in critical situations
You don't have to think about security: With a 3-stage monitoring system, consisting of integrated alarm messages for temperature, door or network disturbances, and additional features such as CO2 emergency cooling and online monitoring, stored samples have the best protection at all times. In the event of a power failure, the electronics are immediately powered by integrated 12-volt batteries. On top of that, in critical situations you will receive a notification to quickly rectify the disturbance.

Mechanical lock
A mechanical lock protects stored samples from unwanted access. The door is opened by means of an ergonomic handle made of aluminum and protected against breakage.

Minimum temperature fluctuations
An important factor in maintaining sample quality is minimal temperature fluctuations. Liebherr low-temperature cabinets have both spatial and temporal lowest fluctuations in the unit.

Low heat generation
Compared to older technologies, an efficient cascade cooling system with HC refrigerants generates significantly less heat. This minimizes the cost of designing a room ventilation system. If heat dissipation through room ventilation is not possible, a water cooling option is also available.

Lower energy consumption
Low-temperature freezers are among the appliances with the highest energy consumption in the research institutions. Liebherr low-temperature freezers are among the most economical models on the market worldwide. Combined with highly insulating vacuum panels, an efficient cooling system allows efficient operation, maximum energy savings and low operating costs.

Connectors
For remote monitoring, all units have a potential-free alarm output and an Ethernet connector. In addition, reading of temperature and alarm records is possible via the integrated USB interface. An optional 4-20mA output allows temperature values to be sent to data logging systems.

ActiveGreen
Cutting-edge cooling technology with environmentally neutral refrigerants and the lowest energy consumption, thanks in part to large-area vacuum heat suppression.

Interior/shelves/interior doors
Both the interior, shelves and interior doors are made of stainless steel. This makes them easy to clean for optimal hygiene.

Flexibly positioned stainless steel shelves
Inside there are three shelves that can be flexibly adjusted in 24 mm increments. They provide
storage flexibility, space saving and adaptability to your needs and requirements.
Additional shelves can be added as an option.

Door sealing concept
The new door sealing concept, which consists of two peripheral seals, enables doors to close absolutely tightly. In addition, it contributes to reducing energy consumption. The seals can be replaced separately and without the use of tools.

Removable stainless steel inner door
Removable stainless steel inner door prevents cold loss when opened and makes it easy to clean
and maintain hygiene.
