Refrigerators / freezers
Published over 5 years ago. See the latest and most current information on Refrigerators / freezers.
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.
