The vessels are the easy part of a cryogenic storage facility. The room and its services are where the planning errors happen, and they are expensive to fix once the floor is down.
The seven
- Ventilation sized for the whole room. Every litre in it, including delivery dewars waiting to be decanted.
- A fixed oxygen monitor with the alarm outside the door. CP30 records the HSE recommendation that workplace oxygen stay above 19.5 per cent.
- Floor loading checked. A CryoBank 1800-95 is listed at over a tonne charged for vapour storage.
- Alarm relay out of the room. ESHRE’s 2026 recommendations call for continuous monitoring with logging. An alarm nobody hears does not meet the intent.
- A backup vessel, or a written transfer plan. For the day a tank fails.
- Level ground delivery access. No vessel should need a passenger lift.
- Room to decant without tipping. A foot pump dispensing dewar needs floor space beside the tank.
The variable facilities teams underestimate
How often the room is entered. Working stock accessed hourly and long term archive opened monthly behave completely differently, and are usually better in separate vessels.
For small footprint working stock beside the bench, the CryoCan 30-6 is 30 litres at 681 mm tall with six canisters.
