Not a Catalog Product. A Built-to-Drawing System.
A liquid cooling loop is an engineered assembly of seamless tube, fittings and manifolds. We take your P&ID or CAD package and deliver a tested, ready-to-install loop — not a box of parts.
- Send your drawingP&ID, CAD, isometric drawings or even a hand sketch with flow rates, coolant type and interface points.
- Engineering reviewOur team checks material compatibility, wall thickness, joint method and routing, then returns a manufacturability proposal.
- Fabrication & weldingIn-house cutting, bending, orbital / argon-shielded welding, passivation and dimensional inspection.
- Leak test & documentation100% helium leak testing, hydraulic pressure test and MTC traceability before packing for export.
Typical engagement: engineering sample first, then batch production. MOQ and lead time are quoted per drawing — tell us your target volume in the inquiry form.
