Liquid Nitrogen Dewars and 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" flask to a large horizontal tank that holds 425 liters. For your cryogenic system, Cryofab engineers efficient flexible hose, vacuum jacketed pipes, bayonets, evacuation components and vacuum jacketed valves. We have years of experience — we’re experts at custom design, OEM manufacturing, short run and long run production.
Designed for liquid nitrogen, liquid oxygen and argon
Ideal liquid nitrogen (LN2) tanks, these portable dewars work equally well with liquid oxygen and liquid argon for low-pressure transport & storage.
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 cryogenic storage tanks for low-pressure transport and storage of liquid nitrogen, oxygen, and argon. Easy to move and conveniently accessible, they are ideal for interaction with LN2 liquefiers. Sizes range from 300 liters to 2000 liters in multiple configurations.
Accessories for liquid nitrogen, liquid oxygen and argon
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.
Accessories for multiple cryogenic applications
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.
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.
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.
