Accu-Freeze Automatic Controlled Liquid Nitrogen

Freeze it and Make Your Pipe Repair Easy!

Accu-Freeze™ is the controlled liquid nitrogen (LN2) pipe freezing system, a method to freeze stationary liquids in a selected section of a pipe or tubing. It is the world’s only patented, digitally controlled pipe-freezing system, allowing you to create an ice plug accurately and safely. By controlling the surface temperature of the pipe, Accu-Freeze™ can safely and accurately form an in-line ice plug capable of withstanding 138 bar (2000 Psi) in pipes up to 12″ (300 mm) diameter.

Major Advantages of Accu-Freeze™
Saves Time	Avoids Shutdowns	Reduces Waste
Prevents the need for draining and refilling systems.	Allows repairs or modifications without shutting off the entire system.	Eliminates handling of contaminated water and saves large amounts of water.
Safety and Cost Efficiency	Standard Products	Accurate Control
Controlled remotely, colder than other refrigerants, and more cost-effective LN2 delivery	Suitable for pipe and tube sizes up to 12" (300 mm).	Automatically controls the freeze temperature.

Key Features and Benefits

Controlled Ice Plug Formation
Only form an ice plug beneath the Accu-Freeze™ coil wrap, jacket, or aluminium clam jacket.

Easy Application
Wrap copper tubing or insulated jacket around the pipe section to be frozen and inject LN2 through the patented control system.

Static Condition
For the ice plug to form, the liquid in the pipe must be static (no flow).

Flexible Voltage
Each unit can be set to 220 V or 110 V, with temperature scales in °C or °F.

Optional Aluminum Jackets
Available for repeated freezes on the same pipe sizes, reducing setup time.

Ordering
Freeze Pipes up to 12" (300 mm) :	Accu-Freeze™ systems are available with coil wraps, jackets, or aluminium clam jackets for pipes 6 to 12" (150 to 300 mm). Adjustable straps allow alteration according to application requirements, creating an ice plug without affecting the pipe's integrity. Detailed user instructions help select an appropriate location for safe freezing.
Applications in the Nuclear Industry:	Accu-Freeze™ can create an ice plug while keeping the pipe wall temperature within allowable limits, suitable for nuclear industry restrictions regarding cryogenic exposure.
Cryogenic Freeze Seal Jackets:	Clam-Shell Design: Popular for repeated freezes, with quick setup and specific pipe size fitting. High-Grade Aluminum: Double-walled for superior performance, easy NPT fittings, rugged, and long-lasting.
