Diesel Exhaust Fluid Heaters
Selective Catalytic Reduction (SCR) is a technology that uses a urea-based Diesel Exhaust Fluid (DEF) and a catalytic converter to significantly reduce oxides of nitrogen (NOx) emissions.
DEF is an important component in keeping heavy-duty trucks and machinery operating within emission specifications. To prevent it from freezing at low temperatures, a DEF Heater is used to return DEF to liquid form. This ensures proper flow through the lines and pump unit.
If your diesel vehicle is operating in limp mode or is not operating at full power, a common culprit is a failed DEF heating element.
