These are the features you should look for when pricing out your low and ultra low-temperature vaccine freezers.

| PRODUCT | Feb. 15, 2021 |

Low and ultra-low temperature freezers for vaccine storage do the same thing your freezer at home does, except better and colder and with more scrutiny and responsibilities.

Yes, they’re very similar.

As your workplace prepares to scale up its cold chain storage, or to invest in low and ultra low-temperature storage for the first time, it only takes a moment to familiarize yourself with the new technology available to support vaccine storage,

If you want the whole rundown, we wrote a comprehensive guide to get your workplace up to speed on the vaccines, storage, and protecting your budget over the long term. If you aren’t ready for that, continue below.

As you approach manufacturers and suppliers for quotes, make sure you receive the quotes on equipment with the features your workplace deems essential.

In our opinion, those features are:

  • Multiple (two) hermetic compressors. Within each, a motor and compressor are housed in a single, sealed unit. This design eliminates the need for compressor maintenance, reducing the chance that vaccines will be exposed to warming temperatures during said maintenance. Additionally, it allows the freezer to recover quickly after warming caused by door opening. But it also generates heat – the opposite of what you want.
  • Compressor cooling. Running a constant flow of refrigerant through the compressors themselves makes your workspace more comfortable since excessive heat doesn’t bleed into the surrounding environment. More importantly, however, is that it eliminates the possibility of heat transfer to samples inside the freezer and abutting the compressors.
  • Variable-stage compressors. A freezer with compressors capable of running in variable stages (at, for example, 20% capacity or 100% capacity, rather than simple ON and OFF) results in smaller and fewer temperature fluctuations, even with external temperatures up to 30°C.
  • Low-pressure designs. Interior layouts engineered for low pressure so temperatures are uniform in every corner of the freezer box.
  • Access control. Users can be given access to the contents of the freezer using custom passcodes. This allows managers to limit access to those workers with the skills and experience required, and to track access in case of a spoilage/waste event. Theft is also a concern, as vaccines have been targeted in previous pandemics. Access control is a reliable answer to this threat.
  • Temperature tracking. Either remotely or in your freezer’s built-in interface, temperature tracking is an important feature for transparency. It ensures you can verify the continuation of the cold chain necessary to preserve the vaccine.
  • Power backups. You have no control over your local power utility and an outage could spoil your entire supply and cost tens of thousands of people their access to the COVID-19 vaccine. Unless you have a reliable power back up, like several models of low and ultra low-temperature freezer do. Some models can be configured to sound an alarm, send an email and text to the site manager, and run for up to 30 hours on backup power.

Naturally, different freezer models employ different combinations of features, but they can be lumped into two categories:

  • Freezers with essential features
  • Freezers with convenience features

Although with the scrutiny that will fall on the health services during COVID-19 vaccine deployment, many of the features previously considered conveniences (like remote access control and text alarm notifications) contribute to transparency and accountability, and may now be considered essential in many scenarios.
