Some tractors, excavators, cranes and other mobile engines that run on diesel, but not on roads, are now equipped with SCR technology, which requires a fluid called AdBlue. AdBlue is filled into a dedicated tank, separate from the one for diesel.
AdBlue is a transparent liquid that is non-hazardous and easy to use. Thanks to SCR technology and AdBlue, these vehicles are cleaner as their NOxious nitrogen oxides emissions are considerably reduced.
SCR technology and AdBlue for NOx reduction is now common in several types of non-road engines, eg:
- Agriculture/farm engines such as tractors and combine harvesters
- Mobile cranes
- Engines used in harbours and airports
- Excavators and engines used in mines or construction
Farmers and the farming community know Yara in the UK & Ireland as the leader in mineral fertilisers. Yara is also a pioneer of AdBlue. We have participated in the creation of the ISO standard for AdBlue, together with the manufacturers of diesel engines. AdBlue is a specific urea solution that is very pure in order to be compliant with the complex SCR catalyst that converts it. This urea solution is produced and distributed in a more refined process to ensure its purity than the urea solution used by the farmers in mineral fertiliser. Therefore, it is sold at a different price to reflect this.
You will find AdBlue sold by Yara under the Air1 brand name. We directly supply farmers and operators of non-road mobile machinery through a network of Air1 distributors all over the UK & Ireland.
We have a complete range of AdBlue solutions for tractors and large non-road engines. Our Air1 commercial team offer its expertise to answer any questions and requirements you may have about AdBlue.
