The
Ultra Helium Dewars
are designed and built for reliable transport. They are light,
maneuverable and durable, while providing superior thermal performance.
The unique neck tube design provides proven support during transportation.
The outboard caster base provides maximum stability in a compact
design.
Available in sizes ranging from 60 to 1,000 liters.
The Ultra Helium Dewars are suitable for air transport with the optional absolute pressure relief valve.
All models are 100% non-magnetic for Magnetic Resonance Imagery (MRI) service.
The Ultra Helium Dewar’s controls are conveniently located on the top, with nesting fill couplings to accept various standard transfer line sizes.
The optional electric pressure builder can quickly increase pressure for liquid transfer while maintaning low heat leak.
It has two pre-set ranges (4 or 8 psig / 0,3 or 0,6 bar) for efficient liquid helium withdrawal.
-
Maximum durability and light weight
-
Outstanding thermal performance
-
Large ball valves for up to 19 mm transfer lines
