Accu-Freeze utilizes liquid nitrogen in a controlled system to freeze stationary liquids in a section of pipe or tubing. By controlling the surface temperature of the pipe, the pipe-freezing system forms an inline ice plug capable of withstanding 2,000 psi in pipes up to 12" dia. The temporary plug isolates the section, thus allowing repairs or modifications to be made without shutting off or draining down the entire system. In cases where water or other fluid systems must be online continuously, the system can be set up, a repair or replacement completed and the pipeline returned to normal in less time.
