2021 NIH Freezer Challenge Results
Eight labs and one IC participated in the 2021 NIH Freezer Challenge to improve freezer management, increase freezer reliability, and reduce energy consumption.
The challenge was held from January 1 to May 1 of 2021. Challenge initiatives ranged from maintenance options, such as defrosting freezers, to laboratory best-management practices, such as changing the temperature setting of Ultra-Low Temperature (ULT) freezers from -80°C to -70°C. Changing the temperature setting of an ULT freezer from -80°C to -70°C reduces the amount of work that the compressor does, which increases freezer reliability and reduces energy consumption by about 20%. These results show the power each lab has to incrase freezer reliabilty while also protecting the environment. Imagine what we could do if the entire NIH joined in! Participate in the 2021 Freezer Challenge to help out!
