Accu-Freeze™ Key Features
The ice plug only forms beneath the Accu-Freeze™ coil wrap, jacket or aluminium clam jacket which is used on a 6 - 12" (150 to 300 mm) pipe or tube and does not expand outside of the range of jacket or coil.
An ice plug is formed by wrapping copper tubing or specially designed insulated jacket around the section of pipe to be frozen. The LN2 is then injected through the patented control system.
The water or other liquid in the pipe or tube needs to be in a static condition (no flow). The Accu-Freeze™ wrap is placed around the pipe up stream from the section to be repaired.
Accu-Freeze™ takes over by automatically injecting the LN2 to a temperature set by the user through the system over the in-line ice plug. Once the plug is formed, maintenance and repair can take place without draining or shutting off the entire system.
Each unit can be set to 220 V or 110 V and a working scale of oC or oF.
Optional aluminium jackets are available.
