We offer custom design, OEM manufacturing, short run and long run production.
Designed for liquid helium
CMSH Series Portable Liquid Helium Dewars
These minimum-loss dewars are perfect for storage, transportation, and dispensing of liquid helium. They feature state-of-the-art vapor cooling and durable construction. TPED, PED, DOT4L & ASME certified dewars available.
CSM/CVSM Series Superconducting Magnet Dewars
Designed specifically to facilitate superconducting magnet research, this efficient and maintenance-free dewar has either liquid nitrogen or vapor shielding. Cryofab offers an expertly engineered vessel, our experience and versatility save time and costs.
C2000 Series Cryogenic Valves
Cryogenic valves in sizes from 1/4″ to 2″ pipe-size weld ends. Ideal for vacuum-jacketed piping, cold boxes, manifolds and tank systems, C2000 valves can be used with liquid nitrogen, helium, argon, oxygen service, and other cryogenic liquids. Precision trim options available.
C3000 Series Liquid Helium Valves
High-quality liquid helium valves in 1/2″ and 1″ pipe-size weld ends. Built in globe- or angle-style bodies with manual or actuated operation. Custom options available. C3000 valves are ideal for vacuum-jacketed piping, cold boxes, helium transfer lines and helium liquefiers.
CB700 Series Cryogenic Bayonets
Tube size high-efficiency connection for vacuum-insulated piping and flex line applications. Threaded connection nut facilitates connection and separation. A nose seal and silicone o-ring assure efficiency and tight sealing at cryogenic temperatures.
Accessories for multiple cryogenic applications
C5000 Series Vacuum Jacketed Valves
Cryocomp C5000 vacuum-jacketed valves are available in 1/4″ to 1/2″ tube-size weld ends in globe or right angle body configuration. Applications for the C5000 Series include vacuum-jacketed piping, cold boxes, helium transfer lines and cryogenic piping systems.
B3000 Series Cryogenic Bayonet Connections
A quick, highly-efficient connection for vacuum-jacketed transfer hose and vacuum-insulated piping systems. Sizes range from 1/2″ tube to 1″ pipe. Designed with a close fit between components for low heat leak. It will operate in the vertical or horizontal position.
V1000 Series Evacuation Valves & Operators
This cryogenic seal-off valve features an integrated port added to a 1/2″ and 1″ standard seal off valves allows a vacuum sensor to be installed without drilling and welding, saving time and eliminating potential leak paths.
V2000 Series Spring-loaded Vacuum Valves
An evacuation valve which is compact, vacuum-tight, has excellent capacitance and offers positive pressure relief. Simple, inexpensive, and reliable, this design ranges in size from 1/4″ through 3″ with matching operators.
