Cutting & bending
Spools formed to isometric drawings with controlled bend radii.
Prefab spools
Materials & fabrication
What We Can Machine, Bend and Weld
Material selection, joint method and surface condition are decided together with the coolant chemistry and the acceptance criteria.
Materials
Seamless Stainless, Traceable by Heat Number
Prime virgin steel from named mills, with documentation attached to every batch.
| AISI 304 | General closed-loop coolant and utility distribution |
|---|---|
| AISI 316L | Higher chloride resistance; specified for DI water and aggressive cleaning regimes |
| Tube form | Seamless, with controlled internal roughness |
| Wall thickness | 0.8 - 3.0 mm typical; project-specified |
| Traceability | EN 10204 3.1 Mill Test Certificates: chemical composition and mechanical values |
| Incoming checks | On-site laboratory, spectrometer and dimensional verification |
Coolant compatibility is reviewed per project. Final material grade is confirmed at engineering review, not assumed from this table.

How to Read Our Compliance Statements
Precision here protects both of us - and matters for Google Ads review and procurement audits.
ISO 9001 compliance describes our quality management system.
NSF / WRAS standards are potable-water material and component standards. They describe materials, not a liquid cooling system approval.
DVGW W534 is a press-fitting test standard. We describe our fittings as tested to it, not as certified liquid cooling equipment.
Mill Test Certificates (MTC, EN 10204 3.1) are material traceability documents supplied with the batch.
None of the above is a system-level liquid cooling certification. If your project requires a specific third-party system approval, tell us at inquiry stage so it can be scoped explicitly.
