How to save energy with my ULT freezer?
Lab Academy
Answer by Dr. Jan-Hendrik Bebermeier, Global Marketing Manager at Eppendorf
This article appeared first in “ Inside Cell Culture ”, the monthly newsletter for cell culture professionals
Sustainability and ULT freezers may seem like an opposing combination: even the latest and most environmentallyfriendly and energyefficient ULTs still require a significant amount of power to maintain extremely low temperatures of -80 °C 24/7. With today’s high energy costs and increased focus on environmental consciousness, energy conservation has become even more important in the lab. But how much energy is needed for the ULT freezer per day at the dedicated -80 °C and in daily, routine operation? How much energy savings and improved efficiency of the cooling system can be relied upon?

How much energy savings and improved efficiency of the cooling system can be relied upon?
- Installation: The instrument should be installed according to the instructions in the Eppendorf operating manual. By definition, this is 150 mm/ 6 in from the back wall and at least 150 mm/ 6 in from lateral objects. The 150 mm are commonly recommended by many suppliers to allow for air movement around the instrument.
- Temperature change: The set point change from -80 °C to -70 °C saves energy. On average, the change results in a reduction of energy consumption by ca. 30% for Eppendorf CryoCube® freezer. These data are based on Eppendorf-external tests with three empty units (230 V) in parallel and 20 °C room temperature.
- Opening: Keep the opening of the freezer as short as possible. If your ULT freezer has inner doors, limit the opening to one door.
- Maintenance and Service: ULT freezers run 24/7 for many years. A few regular maintenance tasks will extend the lifetime of the freezer and ensure optimal energy consumption. Remove dust from the heat exchanger and clean the air filter on a regular basis.
