A folded tube is made out of rolled aluminium and produced by precise multi-step roll forming of aluminum strip(s). The technology has proven to outperform extruded tubes in terms of quality, cost efficiency, environmental impact and HEX performance. Put simply: A better tube at a lower cost.
Two-piece folded tube compared with multiport extruded tube:
- 15% weight savings on the application unit (e.g. condenser)
- 100% higher corrosion resistance
- 100% stronger alloys
- 50–80% higher burst pressure
- 5–15% better heat transfer
