Dewars, tanks, and cryogenic transfer lines for liquid nitrogen, argon and oxygen
CL/CLPB Series Liquid Nitrogen Tanks
Ideal liquid nitrogen (LN2) tanks, these portable dewars work equally well with liquid oxygen and liquid argon for low-pressure transport & storage.
CF Series Dewar Flasks
Open-mouth dewar flasks sized with 4" to 96" diameters and depths 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, semi-conductor, medical, pharmaceuticals & biotechnology. Multiple inside dimensions, lengths, and exterior materials.
CFN Series Low Pressure Container
A robust container for transportation and atmospheric storage of liquefied gases in smaller sizes. A simple dewar with uncomplicated operation, it is a perfect alternative to liquid supply in a lab or plant. Optional features, PED, and ASME dewars 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 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.
CLD/CHD Series Cryogenic Storage and Cryogenic Transport
Cryogenic transport vessels 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.
Accessories for liquid nitrogen, liquid oxygen and argon
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.
Accessories for multiple cryogenic applications
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.
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.
