The ENERGY STAR Final Test Method allows a true, industry-standard comparison of ULT freezer energy use. Prior to the new testing method, freezer manufacturers had their own testing methods, which made it very difficult to accurately compare energy consumption of ULTs. Out of the 15 freezers that were submitted for ENERGY STAR testing in the 2016 CEEL report, five freezers qualified for certification, two of which were Stirling freezers. The SU780XLE had the lowest energy consumption of any of the competitive freezers that were tested by a margin of over 21%.
ENERGY STAR certification will give researchers finding cures for diseases real confidence in the energy savings and environmental sustainability of certified ULT storage products that preserve critical biological specimens for their work. As strong advocates for the ENERGY STAR program, we couldn’t be more pleased to see it finally being realized in our industry, along with the benefits it will bring to the research community.
