Ultra Low Temperature Freezers
The ultimate way to store safely..

Liebherr’s ultra low temperature freezers (ULT) set the benchmark in the temperature range -40 °C to -86 °C: In terms of safety, performance and ease of use, they offer all you need for meeting the demanding requirements of laboratories and scientific institutions, for example. Take advantage of the low operating costs, sustainable cooling, the large interior with practical features and the numerous safety functions of the ultra-low temperature freezers. Place your trust in our extensive experience as a specialist in cooling and freezing.

Features Include:

  • Alarm messages in critical situations
    Don’t worry about security: Thanks to a three stage monitoring system, consisting of integrated alarm messages for temperature, door or mains faults, upgradable features such as CO2 emergency cooling and online monitoring ensure the very best protection for your stored samples at all times. In the event of a power failure, integrated 12-volt batteries immediately supply the electronics with power. You will also be notified in critical situations so that you can quickly rectify the fault.

  • Mechanical Key Lock
    The mechanical key lock protects the stored products from unwanted access. The door is opened with an ergonomic and unbreakable aluminium lever handle.
  • Minimal temperature fluctuations
    In order to maintain the quality of the stored samples, minimal temperature fluctuations are very important. The Liebherr ultra-low temperature freezers have the lowest possible fluctuations both internally within the appliance and over time.
  • Low heat generation
    Compared to older technologies, the efficient cascade cooling system with HC refrigerants generates significantly less heat. This saves costs in the thermal design of the room’s air conditioning system. If heat dissipation via the room air conditioning is not possible, the option with water cooling is also available.
  • Low energy consumption
    Ultra-low temperature freezers are among the devices with the highest energy consumption in research facilities. Liebherr ultra-low temperature freezers are among the most economical models on the market worldwide. In combination with highly insulating vacuum panels, the efficient cooling system allows for efficient operation, optimum energy savings and, as a result, low operating costs
  • Interfaces
    For remote monitoring, all appliances are equipped with potential-free contacts and ethernet interfaces. The temperature and alarm records can also be read via the integrated USB interface. Optionally, a 4-20 mA output enables the integration of the temperature value into existing systems for data recording
