Accu-Freeze Accu-Jackets -Cryogenic Freeze Seal Jackets

Accu-Freeze Accu-jackets LN2 Freeze Seal Jackets Now Available COB Industries now manufactures Freeze Seal Jackets (“clam-shell” style) in addition to the standard Accu-Freeze kits. These Accu-Jackets are popular with customers that need to do repeated freezes on the same size or sizes of pipe. The amount of set-up time is greatly reduced with Freeze Seal Jackets that are manufactured to fit specific pipe sizes and are just bolted around the outside of the pipe. The Accu-Jackets have injection ports built in which connect to the LN2 feed and exhaust ports to vent the gas to atmosphere. They are constructed of high-grade aluminum with a double-wall design that creates an insulating air gap between the liquid nitrogen and the ambient air outside the jackets.
