How we quote

No Fixed Finished-System SKUs

This business is custom integration. The catalog is a component vocabulary, not a price list.

A liquid cooling system combines seamless stainless tube, fittings, manifolds and valve blocks in a project-specific topology. Because the geometry, interfaces and acceptance criteria change with every CDU and every rack layout, we do not publish fixed finished-system SKUs.

Instead, we maintain roughly 30–40 base component families in the catalog, and quote each assembly against the drawing. Tell us the coolant, flow rate, sizes, material, quantity and whether a drawing is available — our engineers come back with manufacturability feedback and an indicative lead time.

MOQ, lead time and customisation options are quoted per project. An engineering sample can be produced before batch production.

Catalogue parameters - indicative, confirmed at quotation
Base component familiesApprox. 30 - 40, grouped into the six families above
MaterialsAISI 304 / 316L seamless stainless, prime virgin steel from named mills
Size indicationFittings DN15 - DN100; tube wall 0.8 - 3.0 mm typical range
ConnectionsV / M press profile, orbital or argon-shielded weld, flange, threaded
Testing100% helium leak test and hydraulic pressure test on custom assemblies
TraceabilityEN 10204 3.1 Mill Test Certificates
