Cryogenic Liquid Nitrogen Dewars & Accessories
“Cryofab makes the best dewars I’ve bought”
—Dr. Jeff Levine
Standard liquid nitrogen dewars are available in sizes ranging from a small 4" cryogenic dewar to a large horizontal tank that holds 425 liters. Cryofab engineers the perfect accessories for efficient cryogenic liquid nitrogen storage and transfer. Products like flexible hose, vacuum jacketed pipes, bayonets, evacuation components, and vacuum jacketed valves. We have decades of experience — we’re experts at custom design, OEM manufacturing, short run, and long run production. Contact us about your project.
Cryogenic Dewars and Transfer Lines for Liquid Nitrogen, Argon and Oxygen
Ideal for cryogenic liquid nitrogen, these portable dewars work equally well with liquid oxygen and liquid argon for low-pressure transport & storage. Pressurized or non-pressurized.
CFUL Series Uninsulated Stainless Steel Flexible Transfer Lines
Uninsulated flexible transfer hose for industry, labs, cryocooler compressors, instrumentation, trailers, cryo-fuels, food service, semi-conductor, medical, pharmaceuticals & biotechnology. Sizes 1/4" to 4" i.d., lengths to 100'. Exterior can be braided, armor, or silicone.
CH Series Horizontal Cryogenic Storage Tanks/Vessels
Horizontal design for low-pressure transport and storage. The ideal cryogenic liquid nitrogen dewar for interaction with LN2 liquefiers. Equally good for liquid argon and oxygen. Easy to move and conveniently accessible in multiple sizes and configurations.
Cryogenic valves in sizes from 1/4″ to 2″ pipe-size weld ends. C2000 valves can be used with liquid nitrogen, argon, oxygen service, and other cryogenic liquids. Choose manual or actuated functions. Can be customized.
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.
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 vacuum seal-off valves are simple, inexpensive, and reliable. Valve sizes range from 1/4″ through 3″ with matching operators. Optional integrated port that allows a vacuum sensor to be installed without drilling and welding.
Designed for the evacuation of large 2.0″ vacuum systems such as cryogenic dewars, vacuum-insulated piping, and MRI magnet vacuum containers. This unique seal-off valve has a compact design that is vacuum-tight during normal evacuation with a spring-loaded poppet for relief.
