A "state of the art" all-aluminium heat exchanger has a manifold (header) at either end of the flat tubes, as illustrated in the picture on the right.

Split condenser: Manifolds are key elements!

Hydro has more than 30 years of experience in manufacturing automotive heat exchanger tubing, and the company is using this competence in HVACR, where the transfer from copper tube/aluminium fin heat exchangers to all-aluminium heat exchangers is underway. The one-piece welded tube manifolds, incorporating a braze clad layer, offer excellent joint formation in a controlled atmosphere brazing (CAB) process.

To meet the needs of the HVACR market, Hydro has developed a standard range of alloys and components to suit a vast array of applications. In addition to these standard products, Hydro offers a rapid prototyping service for customers that need something outside the standard range.

Hydro has developed high-strength alloys that can be used for manifolds where pressures above 160 bar are required.
Hydro manufactures one-piece welded tube manifolds in Workington, UK, and Hannover, Germany. Both facilities offer top-level service and product ans process quality according to ISO/TS 16949 standard.
