Vaccine storage considerations for remote locations

Equitable COVID-19 vaccine access is critical for overcoming a pandemic.  Stirling Ultracold freezer solutions adapt to meet the needs of the most rural or impoverished communities and should be considered in vaccine administration plans.

Remote power
supply

Stirling Ultracold freezers require less power to operate than any other ultra-low temperature (ULT) freezer available.  They are brownout tolerant and smooth incoming currents to protect against surges or poor power supply.  They are compatible with universal voltages and automatically switch between 110-240V or 50-60 Hz based on the incoming supply.

Portable freezer power options

The portable ULT25NEU freezer is perfectly designed for rural community use.  It can run on a 12V battery or plugged in to automobile power sources.  The table below lists power supply options when wall-power may not be available.

Alternative energy power supply

Because the portable ULT25NEU can run on a 12V power supply, a number of alternative-energy power sources are available.  These power sources often rely on collecting solar or wind energy to provide power when available.

vaccination pod

Vaccine Pods integrate Stirling freezers

Vaccine Pods provides pharmaceutical companies, government organizations and NGO’s the ability to streamline cold chain logistics by directly shipping a POD with the vaccine safely stored in a ULT freezer that is powered by the POD’s integrated power source.

ULT freezers are the most reliable option for vaccine storage

Stirling Ultracold freezers come with a wide programmable temperature range of -20°C to -86°C to protect ANY mRNA vaccine. Wireless remote temperature monitoring to track vaccine viability on any internet connected browser, sets up in minutes. Investing in ULT freezers now prepares for the equitable administration of medicines and therapies in the future.
