The Accu-Freeze™ System is available with a coil wrap, jacket or aluminium clam jacket, which is used on a 6 to 12" (150 to 300 mm).

The design of the jacket incorporates adjustable straps, which will allow the user to alter the jacket size according to the application requirements. 

The controlled freeze process safely creates the ice plug without affecting the integrity of the pipe. (Pipe bursts happen when the ice forms in an uncontrolled manner and creates hydrostatic pressure between ice plugs or against a closure in the line). Detailed user instructions are provided to help the end user select an appropriate location to safely freeze the line. 

In the nuclear industry there are also restrictions regarding exposure of certain pipes to cryogenic temperatures. Accu-Freeze™ makes it possible to create an ice plug while keeping the pipe wall temperature within the allowable temperature limits.

Cryogenic Freeze Seal Jackets (Clam-Shell type) are now available 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.
