Choosing a Data Center Thermal Storage Tank Manufacturer: Capacity, Code, Logistics

Selecting a TES tank manufacturer for data centers is a capacity and logistics question as much as a technical one, because data center builds are scheduled and global. This article is a general supplier-audit checklist, focused on demonstrated capacity, code awareness, shipping, and QA, rather than the ASME U-stamp specifics covered separately.

To choose a data center TES tank manufacturer, audit four things: demonstrated capacity to build very large coated tanks, code awareness (AWWA D103 / ISO 28765 for water tanks, ASME where pressurized), global logistics for flat-pack panels, and a retained QA package. The differentiator for data centers is usually schedule certainty and the ability to repeat modules at scale, not a novel design.

Ask for the largest coated tank the supplier has built and the total volume delivered, not just a brochure claim. The Italy Sardinia tank (2025, 30,549 m3), Indonesia Cilincing tank (2024, 21,088 m3), and Namibia array (6 x 11,230 m3) are large coated tanks we delivered, analogous evidence of capacity, not data-center projects.

• Largest tank built, proven.
• Total volume delivered.
• Repeatable module history.
• Capacity, not claims.

For water storage, AWWA D103 and ISO 28765 govern bolted steel tank design and the glass coating; for pressurized TES, ASME enters. A supplier should speak both fluently and state which standard governs your tank. We hold ISO 28765 and AWWA D103 design capability and confirm ASME scope per project.

• AWWA D103 for bolted tanks.
• ISO 28765 for glass coating.
• ASME where pressurized.
• State governing standard.

Data center builds span continents, so flat-pack panel shipping and local erection matter. Confirm the supplier can pack efficiently, document customs, and support local crews or your EPC. The Thailand project (6 people, 12 days) illustrates fast local erection of bolted panels.

• Flat-pack shipping efficiency.
• Customs documentation.
• Local crew support.
• EPC coordination.

Require material certificates, holiday test records on coated panels, hydrostatic test records, and erection torque verification. The table summarizes the minimum.

• Material certificates.
• Holiday test on coating.
• Hydrostatic test record.
• Torque verification.

We have no data-center TES in this library. The large coated tanks cited are analogous industrial and utility deliveries, not data-center projects, offered as evidence of our capacity, code awareness, and logistics.

• No data-center TES in library.
• Citations analogous, not claims.
• Capacity and logistics real.
• Audit us against this list.

The largest coated tank built and the total volume delivered, plus a history of repeated modules, since data centers value repeatability over novelty.

AWWA D103 and ISO 28765 for bolted water tanks; ASME where the TES is a pressure vessel. The supplier should state which standard governs your tank.

Flat-pack panels ship efficiently with customs documentation, and local crews or your EPC erect them; confirm the supplier supports that path.

Material certificates, holiday test records on coated panels, hydrostatic test records, and erection torque verification.

Usually not for data centers; schedule certainty and module repeatability matter more than a unique tank.

Not in our project library. We cite large coated tanks at other clients as analogous capability, not data-center deliveries.

Choosing a data center TES manufacturer is about proven capacity, code clarity, and logistics discipline more than novel design. Verify the largest tank built and total volume delivered, confirm which standard governs (AWWA D103 / ISO 28765 for water, ASME for pressure), and require a full QA record set. For data centers, the winning supplier is the one who can repeat modules on schedule across continents, not the one with the most exotic tank.
