Qwik-Freezer® Pipe Freezing Equipment 3/8" - 8"

Qwik-Freezer equipment 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 forms 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.



ACCU-FREEZE Pipe Freezing Equipment up to 12"+

Accu-Freeze utilizes liquid nitrogen in a controlled system to freeze stationary liquids in a selected section of pipe or tubing. By controlling the surface temperature of the pipe, Accu-freeze can accurately and safely form an in-line ice plug, capable of withstanding 2000 psi in pipes up to 12 inch diameter.
