Vacuum Insulated Line (Single and Multi Line)
CRYO DIFFUSION offers a complete range of tailor-made vacuum super-insulated rigid and flexible transfer lines, single/multiline. Stainless steel piping is used for the inner line.
- Standard working pressure: 10 bar (higher pressure on request)
- Onsite installation and commissioning on request
- Best quality permanent vacuum with little maintenance required
- Full range of options and accessories available
- Outer pipe remains at ambient temperature providing higher safety levels
- Full stainless steel construction for hygiene-critical areas (cryobiological rooms, food and electronics industry, applied research and physics)
- Multi-pipe vacuum insulated lines for liquid helium transfer equipped with copper or aluminium shields are also available
