Heated Lines
To guarantee the functionality of the SCR system at freezing temperatures, all DEF hoses
must be heated and insulated. Electric heated DEF hoses are provided by various suppliers
in any required length. The longer the line the more the power required for defrost. See after-
treatment Technical Data Sheet for heated line power requirements.
The maximum line length is limited by maximum available heating power for the line,
insulation of the line and maximum permitted pressure loss in the line. See aftertreatment
Technical Data Sheet for maximum pressure loss guidance.
