Hewitt Fertility Centre: future proofing a cryogenic repository
Twenty years of monitoring across three sites, then a cryogenic upgrade planned as one project rather than a set of separate purchases.
- Monitoring since
- 2005
- Sites
- Liverpool Women's, Knutsford
- Scope
- LN₂ control and filling
A system that moved with the centre
XiltriX has been the centralised monitoring and alarm system at Hewitt since 2005. It moved with the centre into Liverpool Women's Hospital in 2008 and extended to the Knutsford site in 2013.
The cryogenic upgrade
For the repository upgrade, XiltriX and Cryo Products were asked to consult on liquid nitrogen control, automatic filling and how both would integrate with monitoring. The question was not which vessel to buy, but how the whole storage chain would behave and be evidenced.
The work was broken into stages with clear milestones, which is what made it possible to put the plan in front of the NHS for sign off as a single coherent project.
"By breaking down the challenges into manageable chunks a clear project plan with milestones was delivered and offered to the NHS for sign off."

From cryogenic vessels to 23 benchtop incubators, cleanrooms, power and VOC levels, hosted inside the hospital IT network.
