Carrier Assembly for a Selective Catalytic Reduction System and a Selective Catalytic Reduction System

Abstract

A carrier assembly for a selective catalytic reduction system includes a heater, at least one wire heater, a first holding element, and a second holding element. The heater is configured to heat a working medium from a tank. A first end of the wire heater is connected to the first holding element and a second end of the wire heater is connected to the second holding element. Such a carrier can be included in a supply module and a selective catalytic reduction system.

1 . A carrier assembly for a selective catalytic reduction system, comprising:
 a heater configured to heat a working medium from a tank;   a first holding element; and   at least one wire heater including:
 a first end configured to receive power from a bus bar in the carrier assembly; and 
 a second end connected to the holding element. 
   
     
     
         2 . The carrier assembly as claimed in  claim 1 , wherein the first holding element is a floating element. 
     
     
         3 . The carrier assembly as claimed in  claim 1 , wherein the first holding element is a spring element. 
     
     
         4 . The carrier assembly as claimed in  claim 1 , wherein the at least one wire heater further includes at least one wire with a third end connected to the first holding element. 
     
     
         5 . A supply module for a selective catalytic reduction system, comprising:
 a carrier assembly including:
 a heater configured to heat a working medium from a tank; 
 a first holding element; and 
 at least one wire heater including:
 a first end configured to receive power from a bus bar in the carrier assembly; and 
 a second end connected to the holding element; and 
 
   a pump fitted to the carrier assembly.   
     
     
         6 . A selective catalytic reduction system comprising:
 a tank for a working medium, the tank including an inlet port that enables working medium to enter the tank;   a supply module positioned in the tank, the supply module including:
 a carrier assembly having:
 a heater configured to heat the working medium from the tank; 
 a first holding element; and 
 at least one wire heater with:
 a first end configured to receive power from a bus bar in the carrier assembly; and 
 a second end connected to the holding element; and 
 
 
 a pump fitted on the carrier assembly; and 
   a dosing module configured to receive the working medium from the supply module.
