Cryo Tech Pipe Freezing was established in 2017 by owner David Anderson who had a passion to create the safest and most reliable option for pipe freezing and offer it at a reasonable cost.
Since then, Cryo Tech has continuously delivered exceptional service and has been voted the No. 1 pipe freezing specialist of the Northeast. We use some of the industries leading technology to ensure our services are unparalleled.
If you’re asking yourself – what exactly is pipe freezing? Let’s get you up to speed.
Pipe freezing provides temporary isolation in piping systems for repairs or renovations, it also allows repairs and modifications to be made without shutdowns. With the use of liquid nitrogen, combined with custom-made specialty equipment, we can safely freeze pipes up to 36 inches in diameter on lines that are full of liquid and have no flow. This saves job costs, time, and lots of frustrations.







Non-invasive pipe freezing minimizes downtime, avoiding draining and shutdowns for seamless maintenance and repairs.

Versatile technology freezes pipes for maintenance without damage or leaks.

Pipe freezing cuts repair time and costs by eliminating draining, ensuring operational systems and reduced expenses.

They were one of the best subs I’ve ever had the pleasure working with. They assisted on a project that went wrong every possible way and they could not have been more patient, understanding, professional and amazing at what they do. Would highly suggest them to anyone![]()

Saw them working in Boston. Massive building was business as usual because these guys froze a pipe instead of having to drain the whole system. Technology is very cool and these guys have plenty of it! Extremely professional, friendly and knowledgeable. Highly recommend.![]()

I worked with Cryo Tech on a freeze. They did excellent work and they used thermal imaging to verify the pipe was froze to prevent potential problems. Cryo Tech is the only company that I have seen that uses this technology and it greatly enhances the safety of the job. I would highly recommend Cryo Tech for you pipe freezing projects.![]()

We use many instruments to verify ice formation throughout the freezing process, including pyrometers, thermocouples, thermal imaging devices.
Pipes crack when the ice grows without space to expand. This is usually a closed valve or another ice formation. The technicians at Cryo Tech are trained to ensure proper spacing and pressure venting to avoid this issue
While pipe freezing has no size limit, we currently offer pipeline freezing services up to 36” in diameter.
Draining the entire system or using isolation valves are alternatives to pipe freezing. This will time-consuming, labor-intensive and may cause disruptions.
For a single freeze, we freeze a single point on the line and this means you can mechanically hold back one side. Each freeze will provide a single point of blockage in the line which can be used in the case where one side of the line can be drained. By having two (double freeze) isolation points, you allow a section between the two plugs for modifications.
