Abstract
Fluid conduit segments are provided that include, but are not limited to integrated heating systems for protection against freezing. To this effect PTC-fabric heating elements are provided that are integrated in the fluid conduit segments and that in the negative temperature range include, but are not limited to a PTC-temperature-dependent resistance. The heating system thus provides a higher output in the negative temperature range and a lower output in the positive temperature range, i.e., the heating limits itself until temperature equalization has been reached.
