About airDEFender™ Diesel Exhaust Fluid
Oleo Energies Inc. manufactures and distributes airDEFender™ high purity Diesel Exhaust Fluid (DEF). airDEFender™ diesel exhaust fluid is used in a process called Selective Catalytic Reduction (SCR) to reduce exhaust emission levels of nitrogen oxides (NOx) in diesel engines. airDEFender™ meets or exceeds the relevant ISO 22241 international standard. The standard, outlined in ISO 22241, requires airDEFender™ diesel exhaust fluid to contain 32.5% solution of high-purity urea in demineralised water (Aqueous Urea Solution 32.5%). airDEFender™ is certified by the American Petroleum Institute (API) as a stamp of purity.
The quality control process incorporates many verifications and checks to ensure airDEFender™ always is produced to the high standards demanded by Oleo and our customers.
Equipment checks are routinely done to ensure all equipment, such as scales and flow meters are calibrated correctly ensuring exact measurements of our raw materials and finished products.
Quality assurance testing is carried out on the raw materials.
• Urea – only the highest purity of DEF grade urea can be used when manufacturing diesel exhaust fluid.
• Water – purity testing of our water which has been filtered through a multi-stage system.
Once these checks are performed the manufacturing process can begin.
The quality of each batch is tested in our on-site laboratory with our own specific refractometers to ensure the urea content specifications are met and strictly adheres to the relevant ISO22241 standards.
When you take delivery of airDEFender™ you know you are using the highest grade diesel exhaust fluid in your SCR system!
