SCR systems and fluid lines
for diesel and gasoline

SCR systems

SCR systems for the reduction of nitrogen oxides in diesel vehicles need to function reliably even at low temperatures – and recently this has also applied to gasoline engines. In every case, powerful heat pipes are required. SCR systems from Forschner offer demand-specific variants for passenger cars, commercial vehicles and special vehicles according to a modular



We know ...

... how high variance can be economically mapped with innovative heat pipes.


SCR ssystems for passenger- and commercial vehicles

High production volumes and ultra-short product cycles are the special challenges in the passenger vehicle business. Limited installation space also has to be taken into account, especially where particularly small makes of car are concerned. Our SCR systems for passenger vehicles meet all these requirements.

The components of the heating lines for commercial vehicles and non-road applications largely correspond to the solutions for passenger cars. Here, however, conditions and often tougher. And the total lengths oft he heat pipes are longer. Our SCR systems for commercial vehicles set standards here.

Corrugated pipe

  • As mechanical protection and for coupling of distributor sections
  • Increases stability of entire system

Fabric reinforcement

  • Up to min. 20 bar operating pressure and 80 bar burst pressure
  • With NBR- EPDM- and polyamide supports, volume increase up to 12 percent


Fully-enveloped surface

  • For thermal insulation and long-lasting fixation of heating lines
  • For increased efficiency

Heating-wire braid

  • For additional stabilization
  • Vulcanization avoided for higher process reliability


Inner hose

  • Made from NBR (nitrile butadiene rubber) or EPDM
  • Also available in HNBR for high-temperature applications in commercial vehicles
  • Polyamide dual layer or monolayer


SCR systems - the options

Modular possibilities

In addition to passenger and commercial vehicles, Forschner also knows all about the specific requirements in the non-road sector. On the basis of a modular system we offer market-ready adaptations for mobile cranes, construction machinery, tractors, etc. Small diesel generator sets are also included, as well as all conceivable production volumes, from prototypes and the shortest reaction times to six-figure mass production. In addition to the heating hoses, Forschner has recently introduced CAN-networked control units to its range. Our SCR systems for diesel engines are also known under the brand name FOR-blue.

Sustainable benefits

Our SCR systems avoid cold bridges, intermediate plugs, or leaks. Each hose can be heated individually. Even with non-reverse sucking systems, the PA line retains full indentation resistance. Specifically, especially fast heating up is guaranteed by means of patented electrical contacts. High-quality hose and insulation materials provide significantly higher media resistance and diffusion resistance than competitive products. This is a crucial factor in order to combat aggressive solutions, such as AdBlue with diesel engines – and it also protects against antifreeze, Glysantin, motor oils and fuels.
