Keep patient care running while you fix the problem. Cryo Tech Pipe Freezing provides hospitals with a safe and efficient method to isolate sections of pipe for repair without shutting down critical areas.
Cryo Tech Pipe Freezing provides hospitals with a safe and efficient method to isolate a section of pipe for repair. This process eliminates the need to drain entire systems or shut down critical areas. By utilizing liquid nitrogen and our specialized freeze equipment, we create a solid, temporary ice plug. This ice plug effectively stops the flow of liquid. This allows your team to replace valves, connect new lines, or swap components with confidence. We safely freeze pipes up to 36 inches in diameter on liquid-filled, no-flow lines. The result is less disruption, lower risk, and tighter control of time and cost.
Founded in 2017 by David Anderson, Cryo Tech strives to be the safest and most reliable option for pipe freezing. We offer our services at a reasonable cost. Our team has been voted the No. 1 pipe freezing specialist of the Northeast and serves hospitals nationwide. We bring deep experience, clear documentation, and a calm, professional presence to live clinical environments.
Hospitals have unique constraints. Patient safety, regulatory compliance, and uptime all matter more than anything else. Pipe freezing supports those goals.

Maintain the schedules for operating rooms, imaging suites, patient floors, and sterile processing. We will isolate the specific section that you need to access.

Avoid draining risers, towers, or long hydronic loops. Reduce refill, reheat, and water treatment time.

Less water movement means fewer opportunities for leaks, spray, or unexpected exposure in sensitive areas. Work stays localized and controlled.

Freeze, repair, and return to service in a planned window. Nights and weekends available to match your outage constraints.

Save on labor, chemical treatment, water disposal, and downtime. Fewer trades are affected, and the work area is smaller.

Job Hazard Analysis, method statements, and coordination with your facilities and safety teams are standard on every hospital project.
We review drawings or walk the space with your facilities team. We confirm pipe size, medium, access, and hold time. We help you plan the repair sequence to keep your outage window tight.
We align with your ICRA requirements, hot work rules if applicable, and ceiling access protocols. For sprinkler work, we coordinate impairment permits and fire watch with your life safety team.
You receive written procedures, freeze points, a monitoring plan, and a communications protocol. Certificates of insurance are provided on request.
Our technicians set freeze jackets or engineered freeze heads and establish no-flow conditions. We place containment, mats, and protection for finishes.
We introduce liquid nitrogen and build the ice plug. Temperatures and conditions are monitored throughout. We do not release the line until we verify the plug has achieved strength for the planned work.
Your crew performs the valve swap, tie-in, or component replacement. We keep a technician on the freeze point the entire time and maintain communication with your lead.
We thaw the plug in a controlled manner, check for leaks, assist with venting, and support refill and balancing steps. We leave the area clean and provide a brief closeout report.

We discourage the use of DIY freezing kits on hospital systems. Clinical environments carry higher stakes. Field conditions are rarely textbook. Pipe metallurgy, water chemistry, and line orientation can change plug behavior. Hospital projects demand redundant monitoring, experienced judgment, and industrial-grade equipment. Our crews are trained to recognize edge cases, read the freeze, and make the right call in real time. That is how you avoid costly surprises.

Every hospital is different. Teaching campuses, community hospitals, and specialty centers all have unique routing and redundancy. We tune our plan to your building.

As long as needed for the planned repair, provided no flow is maintained, and job conditions match the plan. We monitor continuously and adjust as conditions change.
Yes. We use clean, external freeze jackets. The liquid nitrogen never touches the water. The method is non-contaminating and does not introduce additives.
We freeze sprinkler lines regularly. We coordinate impairments, tag systems, and support required fire watch. Your life safety team stays informed from start to finish.
No. When performed by trained technicians with proper equipment, the process is safe for standard piping materials. We assess pipe condition and operating history during planning.

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 scope and a firm number. If you prefer, we can join a quick site walk with your facilities lead or mechanical contractor.
