Dewar Range
A magnet’s helium requirement changes across its life — a full cooldown fill at installation, a steady boil-off top-up in routine service, and an urgent refill the moment a level alarm trips. Xpress Helium is built to answer all three from the same standing network, with technicians trained specifically on magnet-side handling rather than general cylinder drop-offs.
Every dewar arrives fitted with electrical heaters and the correct brass adaptor set for your magnet’s OEM fitting, so transfer starts the moment our technician is on site — not after a search for the right connector.
Full cooldown fills for new installations, using calibrated transfer lines and technicians trained on magnet-side procedure.
Scheduled refills booked against your site's known boil-off rate, so helium levels never become a surprise mid-scan-week.
Full cooldown fills for new installations, using calibrated transfer lines and technicians trained on magnet-side procedure.
On-site helium and technical support during ramp-up, ramp-down and quench recovery, alongside your service engineer.
On-site helium coordination during magnet siting and commissioning, working directly alongside your OEM's install team.
Helium and transfer-line support for pre-owned magnet relocations, including first fills after a site move.
We treat MRI helium as a full ecosystem, not a single delivery — from the first litre in the dewar to the moment the magnet is scan-ready again.

Your service engineer flags a low level or upcoming service window, either directly or through your existing OEM contact.
The right dewar size and adaptor set are dispatched, and our technician handles the transfer using calibrated lines.
Levels are confirmed stable before we leave site, with documentation shared for your maintenance records.
