摘要:
A method for heating a fluid line system with at least two electric heating elements (R1, R2, R3), which are operated electrically in parallel and each heating element (R1/R2/R3) is separately supplied with a controlled operating current (I1/I2/I3) for adjusting its heating power. Furthermore, the invention relates to a heating system for such a fluid line system (1), in particular for the application of the method according to the present invention. The heating system has heating elements (R1-R3) which are electrically connected in parallel and are each connected to a separate control element (T1, T2, T3). Each heating element (R1/R2/R3) can be controlled via its associated control element (T1, T2, T3) for the individual adjustment of its heating power.

摘要:
An assembled media line, or a section of a media line, for connecting a tank to a dosing unit in order to add a reducing agent into a SCR catalyst system of an internal combustion engine. The fluid line has electric heating in some sections for heating of the fluid. The fluid line is additionally provided, at least in some areas, with fluid tempering. In use, the media line connects a tank to a dosing unit in order to add a reducing agent in a SCR catalyst system of an internal combustion engine, and wherein the engine coolant is used as tempering fluid. The tempering is achieved by inclusion of at least one tempering line running alongside the fluid line. A line connector for such a media line includes a connecting housing in which the fluid line and two tempering lines can be connected.
摘要:
A heatable fluid line having a pipeline and an electrical heat conductor extending at least over a section of the pipeline. The pipeline has at least two longitudinal sections that are configured differently in respect of the material properties and/or design thereof. At least one first longitudinal section is formed of a first material and a second longitudinal section is formed of a second material. The material of the second longitudinal section is more flexible and/or has a higher resilience than the material of the first longitudinal section. A described method for producing the fluid line relates to an adaptive attachment of the heat conductor on the outside of the pipeline that permits the heat conductor to be wound around fluid coupling and/or connector parts, in particular the housings by means of which the line is assembled, without strand separation.
