Cryo Tech Pipe Freezing provides government and defense contractors with a safe way to isolate pipes for repairs. No full system drain or shutdown required—minimized downtime, reduced risk, and improved schedule control.
Maintain essential services while addressing repairs. Cryo Tech Pipe Freezing provides a safe and precise method for isolating a section of pipe. This service is available to federal, state, municipal, and defense contractors who need to perform repairs. This process does not require draining entire systems or shutting down secured areas.
By utilizing liquid nitrogen and specialized freezing equipment, we create a solid temporary ice plug. This ice plug effectively stops the flow of liquid. This allows your team to replace valves, add tie-ins, or swap components confidently. We can safely freeze pipes up to 36 inches in diameter on liquid-filled, no-flow lines.
The outcome is reduced downtime, minimized risk, and improved control over schedule and costs.
Founded in 2017 by David Anderson, Cryo Tech aims to be the safest and most reliable choice for pipe freezing at a reasonable cost. Our team is recognized as the top pipe freezing specialist in the Northeast. We serve government clients throughout the nation. You can expect experienced technicians, clean setups, thorough documentation, and consistent communication in high-security environments.
Isolate only the section you need. Keep mission-critical spaces and adjacent equipment online.
Skip large drains, refill, purge, and rebalance. Short, predictable outage windows fit tight project plans.
A monitored freeze plug provides single-point isolation when existing valves do not hold or are inaccessible.
Localized work zones reduce water movement, mess, and the number of rooms touched inside secure areas.
Job Hazard Analysis, method statements, COI, and W-9 delivered in the formats your EHS and contracting teams require.
We review drawings, P&IDs, or conduct a controlled site walk with your facilities or contracting officer. We confirm pipe size, medium, access, and the repair sequence that sets the outage length.
We align with LOTO plans, hot work permits where needed, and site access rules. For sprinkler work, we coordinate impairment permits and fire watch with your life safety team.
You receive written procedures that include freeze points, monitoring methods, a communication tree, and emergency considerations. All documents are transmitted through your approved channel.
Technicians set freeze heads or jackets, establish no flow, and protect floors and finishes. We stage mats, barriers, and signage to keep paths secure and organized.
We introduce liquid nitrogen, build the ice plug, and monitor temperatures and site conditions continuously. We do not release the line until the plug demonstrates the strength required for your scope.
Your crew or our partner performs the valve change, tie-in, or component replacement. A Cryo Tech technician remains on the freeze point and stays in constant contact with your lead.
We thaw the plug in a controlled manner, assist with venting, verify flow and leak checks, and support refill and balancing steps. We provide a concise closeout note with time stamps and observations.
DIY freezing kits are not suited for secure government sites. Pipe metallurgy, wall thickness, insulation, and fluid chemistry all affect plug behavior. Restricted spaces add heat loads, vibration, and oversight requirements that DIY gear cannot manage. Government projects demand industrial equipment, redundant monitoring, and experienced judgment. Our teams read the freeze correctly, manage edge cases, and protect your schedule and security posture.
Yes. We follow your access rules, badging, and escort requirements. Tool logs and cylinder counts are maintained throughout.
No. When performed by trained technicians with proper equipment, the process is safe for standard piping materials. We assess age, condition, supports, and loads before work begins.
As long as needed for the planned repair, provided no flow is maintained, and site conditions match the plan. We monitor continuously and adjust as needed.
Yes. We routinely freeze sprinkler mains. We coordinate impairments, tagging, and fire watch with your life safety team and the AHJ.
Tell us your pipe size, medium, approximate length to isolate, number of freeze points, hold time, and location. Add photos if possible. We will return a clear plan and a firm number.
