Diesel Exhaust Fluid Quality Matters

The purity of DEF must be maintained at all levels along the supply line to ensure the end customer does not experience equipment or downtime costs associated without-of-spec DEF.

WHERE IS YOUR DIESEL EXHAUST FLUID COMING FROM?

DEF can be produced through a blending process which combines 32.5% high purity urea – a nitrogen base widely used in fertilizer – with 67.5% de-ionized water.

Blending uses high-purity granules (prill) blended with high-purity water. The urea is highly soluble and non-toxic, which makes the blending process so simple. It's absolutely crucial to know where Diesel Exhaust Fluid is coming from before it reaches your tank. The simplicity to produce DEF generates concern in the market since any trace of contamination can lead to a costly fix.
