How to Run Your Low or Ultra Low Temperature Freezer Efficiently

| PRODUCT | Jan. 18, 2021 |

Modern ultra low temperature freezers are twice as efficient as older models, but they still use about as much energy as a single-family home! At the University of British Columbia in Canada, around 6% of all campus energy use comes from cold storage. Fume hoods are about the only other gear to use more energy (and they use about 3 to 3.5x as much).

Orienting your freezers for efficiency saves your budget and extends the lifespan of the freezer itself, and doesn’t have to impact the performance of the freezer.

How do you do that?

1. Set the temperature to what your vaccine needs, not what the freezer can achieve.

Generally, raising an ultra low-temperature freezer’s set point to -70°C reduces its energy consumption by more than 20% over a set point of -80°C. According to studies, freezers also work about 56% harder to maintain that -80°C set point, resulting in significantly more wear on your compressors (and reducing the lifespan of the entire freezer)1.

2. Think before you open the door.

Opening the door less frequently and for shorter durations will reduce temperature fluctuations and, accordingly, energy consumption. As you plan out your vaccine deployment schedule, organize your vials inside the freezer to limit door opening as much as possible. If workers with access know exactly where their next set of vials is located, it should only take a few seconds to retrieve them and close the door(s). Fill space gaps in your freezer with frozen water bottles to reduce the temperature fluctuations associated with door opening.

3. Defrost your freezer at least annually.

Some freezers eliminate this need with automatic defrost technology. This is only available in units with a maximum low temperature of -30°C due to temperature dynamics below this level. Manual defrosting consists of multiple steps that take about two days to complete. Every lab needs a backup freezer to store samples during defrosting. If you don’t perform this maintenance, your freezer will die before its time and consume energy gluttonously in its short lifespan.

The more you know…

There’s much more to know about low and ultra low temperature freezers – the ones required for vaccine storage (for COVID-19 and others) across the country.

So we wrote about it.

  • About what your organization needs to participate in the rollout of the early COVID-19 vaccines.
  • About how the freezers work.
  • About the features that matter most for high-value vaccine storage.
  • ..and more.
