If you’re using a selective catalytic reduction (SCR) system you need diesel exhaust fluid (DEF) for the system to work. Our products that utilise SCR are designed to reduce the amount of DEF in your system. The benefits of this are simple – if customers consume less, they save money. It’s also easier to package, with smaller DEF tanks to be installed and less storage space needed.
The process of selective catalytic reduction (SCR) in our engines is invisible to the operator. The only action required on their part is to ensure the diesel exhaust fluid (DEF) tank is refilled as required.
To keep operator running costs to a minimum, we have minimised the amount of DEF required,as a percentage of the diesel consumed. For our 1200 Series engines utilising SCR, the amount of DEF required is within the range of 3-4 percent of the diesel consumed. For our 854 range of engines that utilise SCR, the amount required is around 3-5 percent of the diesel consumed.
