Stanford Marks 10 Years of Energy System Innovations
The SESI program transformed the university’s energy system into one that’s safe, sustainable, and resilient and serves as a model for the world.
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.
