Abstract
Tubing for a liquid medium that is to be conditioned, including an inner tube for the liquid-medium that is to be conditioned encompassed by an outer tube, parallel to the inner tube. An outermost tube surrounds the outer tube. At least one duct for the liquid conditioning medium, is disposed between the inner tube and the outer tube and at least one duct for the liquid conditioning medium is disposed between the outer tube and the outermost tube. A redirecting region connects the ducts between the inner tube and outer tube and the outer tube and the outermost tube. The inner tube and the outer tube consist of thermoplastic plastics, and the unit, consisting of the inner tube and the outer tube, is produced by co-extrusion.
