Accu-Freeze Controlled Liquid Nitrogen
Pipe Freezing System (LN-2)


The patented Accu-Freeze™ system is the most advanced pipe freezing system in the world. It utilizes liquid nitrogen in a controlled and automated system to safely and reliably freeze static liquids in a selected section of pipe or tubing. The standard Accu-Freeze™ AF1000 Kit is used to create an in-line ice plug capable of withstanding 2000 PSI in pipes up to 12 inches in diameter and can be modified to handle even larger diameter jobs. Ice plugs (or "freeze seals") temporarily isolate sections of pipe for as long as necessary, allowing repairs or modifications to be made without shutting off or draining down the entire system.

Safely and Reliably Freezes Your Pipe

Accu-Freeze uses its patented control system to accurately and safely create an ice plug

The ice plug only forms beneath the Accu-Freeze coil wrap (coil wrap is used on a 2" to 6" pipe) and freeze jacket (jacket is used on a 6-12 inch pipe.) and does not expand outside of this point. This controlled plug does not create enough pressure to affect the integrity of the pipe. Pipe bursts happen when ice forms in an uncontrolled manner and creates hydrostatic pressure between ice plugs or against a closure in the line.

Accu-Freeze customers have requested pipe-freezing systems that will:

  • Be able to freeze large diameter pipe
  • Control the entire freeze process
  • Minimize exposure to nuclear applications of the pipe
  • Controls the flow of liquid nitrogen through the coild wrap or freeze jacket
  • Not available in: CA, NV, AZ, CO, NM, OR, WA, ID, UT, TX, and MT.
