Ultra-Low Temperature Freezer Maintenance

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. 

Top Tip: 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!

Below are more resources for maintaining your ULT freezer. Always consult the manufacturer’s instructions before attempting any maintenance procedures.
