Pipe Freezing Kits
Pipe Freezing Kits are an effective and efficient method of isolating sections of pipe for repair and maintenance, valve replacements etc. This is done by freezing the contents of the pipe to create an internal ice plug. This eliminates the need to drain long sections of pipe and reduces shut-down time. Pipe Freezing or “Ice Plugging” was first used by the US Navy in the 1940’s and is now a common practice in building maintenance and countless applications in the piping industries
Qwik-Freezer
Pipe Freezing Kits
COB Industries, Inc. first introduced the Qwik-Freezer® kits over 30 years ago and there are now thousands of pipe freezing kits in use around the world. Qwik-Freezer® kits are a portable, affordable and effective liquid CO2 system with pipe freezing kits available for up to 8” pipe. Qwik-Freezer® kits are used by plumbing and maintenance contractors, power plants, water utilities, the US Navy, etc.
Accu-Freeze
Pipe Freeze Kits
The patented Accu-Freeze® Kit liquid nitrogen system was created to meet a specific need in the power generation industry for “controlled pipe freezing”. In other words, the ability to freeze pipes to create an ice plug while controlling the temperature that the pipe wall is subjected to. Accu-Freeze Kits include a digital controller and a solenoid header assembly that allow the operator to actually set and control the temperature of the pipe wall. The system then automatically injects the necessary amounts of LN2 required to freeze the pipe to the programmed temperature.
