Cryogenic Dewars and Transfer Lines for Liquid Nitrogen, Argon and Oxygen
CL/CLPB Series Liquid Nitrogen Tanks
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.
CF Series Dewar Flasks
Open-mouth cryogenic dewar flasks sized with 4" to 96" diameters and depths up to 20'. This flexible container has numerous options so it can be perfectly suited to lab, industrial, or technical applications.
CFCL Series Liquid Nitrogen Transfer Line/Hose
Vacuum-jacketed flexible transfer hose/lines for industry, labs, instrumentation, trailers, cryo-fuels, food service, semiconductors, medical, pharmaceuticals & biotechnology. Multiple diameters, lengths, and exterior materials.
CFN Series Low Pressure Container
A robust container for transportation & atmospheric storage of cryogenic gases. This simple dewar has an uncomplicated operation, it is a perfect alternative to liquid supply in a lab or plant. Optional features, PED, and ASME dewars are available.
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.
Vacuum Jacketed Cryogenic Pipe Systems
Vacuum jacketed/insulated piping fabricated to customer-supplied specifications. Sizes 1/4" up to 2"o.d. inner pipe. Bayonets, VJ valves, Manifolds, in-line relief, expansion joints, elbows, tee sections, traps, and keepfuls are all part of this product mix.
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.
CLD/CHD Series Cryogenic Storage and Cryogenic Transport
Cryogenic transport vessels are designed to mount in vehicles, with features that make the delivery of liquid gases safer and easier. Made to DOT 4L specifications in sizes from 300 liters to 425 liters.
Dewar Accessories
C2000 Series Cryogenic Valves
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.
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
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.
V2000 Series Spring-loaded Vacuum Valves
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.
