Qwik Freezer pipe freezing kits utilizes liquid carbon dioxide (CO2) to freeze stationary water in selected sections of pipe or tubing. By producing very low “dry ice” temperatures, Qwik Freezer pipe freezing kits form a secure in-line ice plug. This temporarily isolates the water in the system and allows repairs or modifications to be made without draining down or shutting off systems.
The Qwik Freezer kit is easy to use. A specially designed Qwik Freezer jacket is wrapped around the pipe at the point where the freeze is required. A nozzle on the Qwik Freezer jacket is then coupled to a cylinder of liquid CO2 by means of a high pressure hose. When the liquid CO2 is injected into the space between the Qwik Freezer jacket and pipe, it immediately expands to form a solid carbon dioxide (dry ice) at a temperature of -109ºF (-78ºC). This low temperature quickly freezes the contents forming a secure “ice plug” which seals the pipe.
The Qwik Freezer “ice plug forms only in a section of pipe covered by the jacket so the resulting rise in pressure is very small and there is no damage to the pipe. The Qwik Freezer pipe freezing kit can be used safely on iron, lead, stainless steel, copper, brass and plastic pipe.
Qwik Freezer kits consist of insulating pipe jackets, reinforced high pressure hose, fittings, insulated work gloves, a rubber mallet, safety glasses, operating manual, timing log and carrying case.
