Custom integration

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.

Process

Four Steps From Drawing to Shipment

One team, one set of drawings, one test record.

  1. Send your drawingP&ID, CAD, isometric drawings or a sketch with flow rates, coolant type and interface points.
  2. Engineering reviewMaterial compatibility, wall thickness, joint method and routing checked. A manufacturability proposal comes back before anything is cut.
  3. Fabrication & weldingIn-house cutting, bending, orbital / argon-shielded welding, passivation and dimensional inspection.
  4. Leak test & documentation100% helium leak testing, hydraulic pressure test and MTC traceability before packing for export.

Scope

What Integration Actually Covers

The value is in the interfaces and the verification, not in the parts list.

Interface engineering

Port positions, connection types and isolation points are matched to CDU, rack and facility drawings before fabrication.

Drawing-driven

Joint strategy

Press, orbital weld, flange or threaded connections selected for the coolant, pressure and installation constraints.

Per project

Prefabrication

Spools and skids built and tested in the workshop so hot work inside a live facility is minimised.

Prefab spools

Verification

Helium leak test, hydraulic pressure test, dimensional inspection and heat-number traceability.

100% on custom assemblies

Documentation

MTC 3.1, test records and part identification packed with the shipment.

EN 10204 3.1

Scale-up

Engineering sample first, then batch production with agreed MOQ and lead time per drawing.

Sample to batch

Quality

Verified Before It Leaves the Workshop

Testing is part of the deliverable, not an optional extra.

Leak testing100% helium leak testing on custom liquid cooling assemblies
Pressure testingHydraulic pressure test to the agreed project criterion
Material checksChemical composition and mechanical values via EN 10204 3.1 MTC
DimensionalIn-process inspection, flattening / widening ductility checks, online ultrasonic scanning
Quality systemISO 9001 compliance

NSF / WRAS material standards and DVGW W534 describe component-level compliance and press-fitting tests. They are not liquid cooling system certifications.

Next step

Start with an engineering review

Send your P&ID, isometric drawing or even a hand sketch. We reply with manufacturability feedback first.
