Pre-cooling
MRI Magnet Pre-Cooling
Controlled pre-cooling of magnet components before liquid helium filling, reducing thermal stress and helium consumption.
Why it matters: Lower helium cost and a safer, more predictable commissioning.
Liquid helium, high-purity gas, and the engineers who fill it
Helium Filling & Supply
Liquid helium in cryogenic dewars and high-purity helium gas, with controlled on-site filling for MRI systems of all major brands.
Why it matters
The problem we solve
Helium maintains the superconducting state of an MRI magnet, cooling it to the extremely low temperatures required for stable magnetic field generation.
What we provide
We supply liquid helium in cryogenic dewars along with high-purity helium gas (Grade 4.5 and Grade 5), and our trained cryogenic engineers carry out controlled filling procedures for MRI systems of all major brands.
The result: Less helium lost, lower quench risk, more scanner uptime.
How it runs
The process, step by step
Each stage is completed and checked before the next begins.
- 01
Pre-fill assessment
The system is checked before anything is transferred, so the fill starts from a known state.
- 02
Controlled filling
Helium is transferred step by step rather than in one pass, keeping the magnet within its thermal limits.
- 03
Continuous monitoring
Pressure and temperature are watched throughout the transfer, not sampled at the end.
- 04
Post-fill checks
System checks confirm magnet stability before the engineers leave site.
What you get
Benefits for your department

Who it is for
Teams this service supports
Hospital administrators
Keep scanners available and costs predictable. We handle helium, cooling and equipment projects so your department avoids unplanned shutdowns.
Diagnostic centre operators
Every hour a scanner is down is lost revenue. Preventive cryogenic and cooling-system work keeps your systems running.
Research facilities
Liquid helium, high-purity helium gas and cryogenic support for research and laboratory work, not only clinical MRI.
Biomedical engineers
A technical partner for cryogenics: helium filling, pre-cooling and cold head, compressor and chiller service on MRI systems from the major manufacturers.
Related services
Often combined with
Cooling components
Cold Heads, Compressors, Absorbers & Chillers
Maintenance, repair and replacement of the cold heads, compressors, absorbers and chillers that hold an MRI magnet at temperature.
Why it matters: Stable cooling, fewer surprises, longer component life.
