Frequently Asked Questions

Vaccine Freezer Cold Storage Solutions

• Are other temperature ranges available to accommodate storage needs for different vaccines?
  Yes. Our walk-in cold storage rooms are available in any temperature range as cold as -80C to +70C for any condition needed of the vaccine cold chain.


• Can the multi-environment freezer rooms compartments and rooms be customized?
  Yes. The general layout shown in the images are just one example. All cold storage rooms may be configured to your needs. Any combination of cold, freezing, and ultra-low freezing can be arranged.


• Would it be better or simpler to buy a farm of ultra-low upright freezers to store in a large lab space?
  No. It may be simple to purchase freezers in that traditional way, but would be very costly considering the ‘total project cost’. The BioStore approach offers singular ultra-low conditioning packages with single power feeds and single maintenance points. With a traditional freezer farm, upfront building upgrade costs increase, building heat rejection increases, and annual maintenance becomes very costly as required for each and every freezer.


• I would need a ‘failure-proof’ ultra-low system for the long term, but equipment would obviously need replacement over the very long term. How is this done without interrupting the freezer space?
  The unique BioStore design puts all ultra-low conditioning equipment completely outside of the freezer space, and the conditioning is always considered as redundant; there is a primary and backup system. Each system has no mechanical dependence upon the other. Each system will fully sustain the conditions. Each system can be physically separated from the freezer space, allowing off-line service.


• Other than space / footprint required for the BioStore arrangement, what are the other primary building considerations?
  The BioStore room requires adjacent space for mechanical equipment. This could be considered as a ‘mechanical room’. The room requires cooling water for the refrigeration equipment. This can be potable water, tower water, or even chilled water. Lastly, redundant electrical feeds (qty 2) are required. Redundant feeds insure that single circuit breakers do not jeopardize operation of both conditioning systems.


• Our facility has backup generators for electrical power. The cooling water source is also redundant. What IF the power or water is lost due to extreme situations?
  When product value dictates a third level of redundancy, LN2 (liquid nitrogen) is the best backup option. An LN2 feed provides the cooling necessary when all refrigeration is lost, while an integral UPS system provides the power to operate the temperature control and circulation fan during power loss.
