Danica Sun ’28 explored smarter resource use for one of Stanford’s major computing clusters.
The typical lifespan of an ultra-low temperature (ULT) freezer is 12-15 years. Properly maintaining your ULT freezer will increase its useful life, reduce temperature fluctuations, and minimize energy consumption.
Chill Up Freezer Set Points
Reduce the energy consumption of your ultra-low temperature freezers by changing the set point from -80 degrees Celsius to -70 degrees Celsius. Chilling up your freezer will save over 1000 kWh and over $100 in energy costs every year. It also prolongs your ULT freezer’s lifespan!
ULT Freezer Maintenance Resources
Always consult the manufacturer’s instructions before attempting any maintenance procedures.
