BULK TANKS
REPAIR & REHAB

CTR Cryo refurbishes cryogenic bulk tanks designed for the storage of liquefied gases such as liquid nitrogen (LIN), oxygen (LOX), and argon (LAR) in industries where safety and uptime are critical, including healthcare, food processing, and industrial manufacturing.

These tanks require highly specialized care to preserve insulation, prevent product loss, and maintain performance under demanding conditions. Our process ensures that your tank systems continue to operate at peak efficiency, regardless of age or application.

Our shop-based Bulk Tank Refurbishment capabilities and services include:

• Inspection & Testing – Comprehensive inspection, leak detection, and pressure testing to confirm structural and operational integrity.
• Surface Prep & Coating – Shot blasting / sandblasting, priming, and application of a two-part high-strength epoxy paint system for long-term environmental protection.
• Component Replacement (Valve Replacement) – Replacement of vacuum valves, thermocouple tubes, safety relief diverter valves, and tank safety valves.
• Instrumentation – Repair, replacement, and calibration of instrumentation including level gauges, thermocouples, and related monitoring devices.
• Vacuum & Insulation Enhancements – Vacuum relief plate replacement, warm/cold retention testing, and perlite insulation top-off to restore thermal performance.
• Piping & Valve Upgrades – Full replacement of piping systems, valves, CGA fill connections, liquid level gauges, and associated flow control components.
• Enhanced Safety Features (Safeties & Regulators) – Installation of pressure-building regulators, safety devices, and 3-way diverter valves to meet current safety and operational codes.
• Customer Logo Application – Application of customer branding and identification markings as part of final finishing and refurbishment.
• Engineering Oversight – All work reviewed and certified to meet ASME standards and customer-specific requirements.

In addition to shop-based refurbishments, CTR Cryo provides expert field services for tank installation, integration, and recommissioning.
