New ULT Freezers Combine Sustainability and Efficiency

Liebherr's new ultra-low temperature freezers are specifically designed for extreme storage temperatures from -40ºC to -86ºC. They are used for short and long term, ultra-low temperature storage of sensitive samples such as DNA, viruses or proteins and vaccines, including some of the new mRNA vaccines.

In order to achieve temperatures as low as -86ºC, a special cooling system is needed which differs from that in normal refrigerators. In its ultra-low temperature refrigerators, Liebherr currently uses the most energy-efficient cooling system. This is cascade cooling with two refrigeration circuits and environmentally friendly hydrocarbon refrigerants. The appliances are therefore highly energy efficient and sustainable.
