Diesel Exhaust Fluid

DEF

What is it?
Diesel exhaust fluid (DEF) is a non-toxic, colorless, odorless solution of urea and purified water.

What is it for?
It is added to the exhaust gases to break down NOx into harmless water and nitrogen.

Where can it be purchased?
DEF will be readily available at New Holland dealers throughout your area.

Is it new?
SCR technology is currently being introduced for on-road applications in North America, and DEF distribution will be in place by 2012, when off-road Tier 4 regulations come into force.

Trucks with SCR technology have been running throughout the world for some time, relying on a well-established DEF distribution network.
