Stainless Steel Components for Data Center Cooling Systems
Powering the Future of Data Center Cooling
As AI workloads and high-performance computing drive unprecedented demand for liquid cooling, data centers are turning to stainless steel vessel components for the reliability, thermal performance, and corrosion resistance their cooling infrastructure requires.
Tank Components Industries supplies the critical stainless steel and nickel alloy cooling system components that OEMs and integrators need to build immersion cooling tanks, coolant reservoirs, buffer tanks, and thermal storage vessels. From tank heads and cylinders to manways and sanitary fittings, our products are engineered for the high-purity, high-performance environments that modern data centers demand.
As a pure components manufacturer, TCI partners with you — we don’t build complete tanks or compete with your business. We provide the precision-manufactured building blocks so you can deliver world-class cooling systems to your customers.
Stainless Steel Data Center Cooling Components Engineered for Performance
Tank Heads
ASME-code stainless steel tank heads form the structural foundation of immersion cooling tanks, coolant reservoirs, and thermal buffer vessels. Available in elliptical, torispherical, flat, and conical configurations to meet your design specifications.
Cylinders
Precision-rolled cylinders serve as the body of stainless steel coolant reservoirs, heat exchange vessels, and pressurized cooling system enclosures. Custom diameters and wall thicknesses available to meet your exact cooling capacity requirements.
Manways
Full-opening manways provide essential maintenance access to immersion cooling tanks and coolant reservoirs, enabling routine fluid changes, filter replacement, and component inspection without system disassembly.
Sight Glasses & Lights
Sight glasses allow visual monitoring of coolant levels, fluid clarity, and flow conditions inside sealed cooling vessels — critical for maintaining system performance and catching issues before they become failures.
Sanitary Fittings
High-purity stainless steel fittings ensure clean, leak-free connections throughout cooling fluid circuits. Sanitary clamps provide secure, tool-free assembly and disassembly, making routine maintenance fast and straightforward. Tri-clamp and other sanitary connection styles maintain fluid integrity and simplify maintenance.
Handholes
Compact access points for inspection, sensor installation, and minor servicing of cooling vessels without requiring full manway openings. Ideal for smaller tanks and tight installations.
5-Axis Cutting
Custom precision cutting for complex cooling system geometries, port openings, and specialized penetrations. Our 5-axis capability ensures exact tolerances for components that must integrate seamlessly into engineered cooling systems.
Why Stainless Steel Is the Standard for Data Center Cooling
Corrosion Resistance
304 and 316 stainless steel alloys resist degradation from glycol-based coolants, dielectric fluids, and treated water, delivering long-term reliability where copper and plastics fall short.
Thermal Performance
Superior heat transfer characteristics enable efficient thermal management in high-density server environments where every degree matters.
Structural Integrity
Stainless steel handles the pressures and stresses of both single-phase and two-phase cooling systems, supporting compact modular designs.
Leak-Free Reliability
Precision-welded, stainless-steel components minimize failure points in cooling systems where even small leaks can mean catastrophic downtime.
ASME Compliance
TCI manufactures to ASME code standards, meeting the pressure vessel requirements that data center cooling systems demand.
Sustainability
Long lifecycle, recyclability, and low maintenance requirements align with the sustainability goals driving modern data center design.

Frequently Asked Questions
What's the best material for immersion cooling tanks?
316 and 304 stainless steel are the standard materials for immersion cooling applications. 316 is preferred where resistance to dielectric fluids and engineered coolants is critical; 304 is a reliable, cost-effective option for less demanding coolant chemistries. For aggressive operating conditions, nickel alloys are also available. TCI manufactures tank heads, cylinders, and fittings in all three materials to suit your system design.
Can TCI manufacture custom components for proprietary cooling system designs?
Absolutely. Our 5-axis cutting capability and custom fabrication expertise allow us to produce components to your exact specifications.
Do you supply components for two-phase cooling systems?
Yes. TCI manufactures stainless steel vessel components for both single-phase and two-phase liquid cooling systems, including the pressurized enclosures and precision-fitted tank heads that two-phase applications require. Our ASME-compliant manufacturing and 5-axis cutting capability mean we can accommodate the tighter tolerances and custom geometries that two-phase system designs often demand.
What types of cooling vessels do your components support?
TCI components are used in immersion cooling tanks, coolant reservoirs, buffer tanks, heat exchange vessels, and thermal storage systems. Whether you're building a single-rack immersion unit or a large-scale modular cooling infrastructure, we manufacture the tank heads, cylinders, manways, fittings, and access components to your exact specifications.
Do your pressure vessel components meet ASME code requirements?
Yes. We manufacture components for both ASME and non-ASME vessels, and can provide documentation to support your code compliance requirements.
Do you work with cooling system OEMs and integrators, or only large manufacturers?
We work with OEMs, system integrators, and engineering firms of all sizes — and as a dedicated data center cooling components manufacturer, our entire operation is built around supplying components, not competing with you. TCI's model is built around being your manufacturing partner. We supply precision components so you can focus on building and delivering complete cooling systems. Whether you need a short prototype run or high-volume production, we're set up to support you.
What's the minimum order quantity for custom cooling components?
We don't enforce a rigid minimum — contact us with your project specs and we'll work with you on quantities that make sense for your timeline and budget. Custom components are quoted individually based on material, configuration, and volume.
What is the typical lead time for data center cooling components?
Lead times vary by component type, material, and quantity. Contact us for a quote and we’ll provide a detailed timeline for your project.
