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.
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.
Only form an ice plug beneath the Accu-Freeze™ coil wrap, jacket, or aluminium clam jacket.
Wrap copper tubing or insulated jacket around the pipe section to be frozen and inject LN2 through the patented control system.
For the ice plug to form, the liquid in the pipe must be static (no flow).
Each unit can be set to 220 V or 110 V, with temperature scales in °C or °F.
Available for repeated freezes on the same pipe sizes, reducing setup time.
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.
Accu-Freeze™ can create an ice plug while keeping the pipe wall temperature within allowable limits, suitable for nuclear industry restrictions regarding cryogenic exposure.
Allow enough space between the ice plug and closed connections to avoid hydraulic ram effects.
"The purge meters are second to none."
"I am a huge fan of Huntingdon products and have talked to others over the years about using them. The purge meters are second to none. I own and use regularly my PurgEye 100 and my PurgEye 300. I think somewhere, I still have my original Argweld® MKV monitor, which sadly no longer powers up. I am a scarce breed because I have 3 degrees and a complete academic understanding of metallurgy, but more importantly, welding science; I also have over 20 years of hands-on experience in welding on drill floors, firing lines, and vessel shops. I quite literally have a passion for old-fashioned welding! Excellent product, guys!"

"One of the best, if not the best, residual oxygen detector instruments on the market."
"I believe the PurgEye to be one of the best if not the best, residual oxygen detector instruments on the market with its digital residual oxygen level LED display readouts measuring as low as 0.01% and its large, user-friendly viewing screen making it easier for me to read. I also believe the PurgEye has great accuracy in residual oxygen, with speedy measurements displayed within seconds. The PurgEye is a far cry from the old school homemade 'use a cigarette lighter' to check purge gas flow system."

"Purge monitors are a necessity."
"I can personally vouch for purge monitors. When working with medium to large-diameter exotic pipework, they can prevent you from having a terrible day! I've only used the older model, which was a godsend. Anyone, from the welder who has had to carry out weld repairs due to root weld oxidation (or coking) on such materials, to the directors facing an expensive bill for re-work and possible tarnished company reputation, to the client with their project now running behind schedule - knows exactly what I mean. Purge monitors are a necessity."
