How To Produce Your Own Diesel Exhaust Fluid

Product Spotlight: Benecor Inline Blending and Dissolving System


Benecor offers the latest, most advanced inline blending and dissolving technology to produce the highest quality of diesel exhaust fluid.

Engineered for Customization

The Benecor Inline Blending Systems allow you to product DEF solution with concentrations up to 50%. 1.050, 2.375 and 4.750 gallons of diesel exhaust fluid can be produced per hour.

Heat Plate Exchanger

To reach high temperature of demineralized water, the Benecor Inline Blending Systems contain a heat plate exchanger in order to reach required temperature for inline blending (at least 86°F / 30°C). The user needs to supply hot water or steam to the heat plate exchanger to make it function.

DEF Debagging Unit

Hopper with capacity of 70.6 ft3, 141.3 ft3 or 247.2 ft3 (2m3, 4m3 or 7m3) contains minimum loading sensors and alarm. Hopper has build in top grid which serves as sieve with mesh size 0.39in x 0.39in (10mm x 10mm). Urea crusher (lump breaker) can be integrated in the hopper.

Screw Conveyors

Screw conveyors are fully integrated in the functionality of the Benecor Inline Blending Systems.


The total diesel exhaust fluid system fits in only one 40ft container (without water and DEF storage tanks).

Double Reverse Osmosis Water Treatment System

Can produce 264.1G/h, 528.3G/h or 1320.8G/h (1m3/h, 2m3/h or 5m3/h) of demineralized water depending on the size of the machine.
