SCR catalyst technology allows much greater NOx conversion efficiency,thereby allowing the engine to be fully optimized, which contributes to this fuel economy improvement.

Heavy duty engines utilizing SCR will provide substantial fuel economy improvement, estimated up 3 to 5%.

Another benefit to the improved fuel efficiency is less frequent DieselParticulate Filter (DPF) cleanout, thereby further reducing costs.

D.E.F is a registered trademark for AUS32 or Aqueous Urea Solution.

D.E.F is a trademark owned by The German Association of the Automotive Industry (VDA).

The right to use the name D.E.F can only be acquired by a license.

A non toxic, crystal clear & synthetically produced solution.

Used in SCR system to reduce NOx emissions from exhaust of diesel vehicles.

It is carried in an additional tank that is fitted by the vehicle manufacturer.

ISO 22241 standard ensures its consistent quality. In 2006, Euro pean heavy-duty diesel market, implemented SCR technology to enable trucks to meet the Euro IV and V limits.

An SCR system uses D.E.F to reduce NOx to water vapor and atmospheric nitrogen.

SCR technology is more fuel efficient than EGR technology to the tune of 3-5%.

D.E.F consumption is expected to be approximately 4-6% of fuel consumption. It may vary depending on vehicle operation,duty cycle, geography, load ratings, etc.

Recommended storage temperature for D.E.F is between -11 deg C to 30 deg C

At constant temperature up to 30deg C, the product will last 12 months minimum

At constant temperature up to 35 deg C, the product will last 6 months minimum

Locations with higher ambient temperature, D.E.F tanks should be insulated or stored under shade with proper ventilation

Vehicles that use D.E.F have indicators on the dashboard that alert the driver of the quantity of D.E.F on board. A gauge similar to a fuel gauge will indicate the level of D.E.F.

If the vehicle is operated such that one would run completely out of D.E.F, vehicle power will be reduced making it compulsory for the driver to refill the D.E.F tank.

Make sure to carry some emergency supply along with the vehicle to reach the next D.E.F refilling point.

Once the tank has been refilled the engine will resume normal power levels.

Dry, well-ventilated and properly covered area.

Avoid direct sunlight.

Optimum storage temperature is 25 deg C (77 deg F), with temporary exposure to higher temperatures has little to no impact.

Being a corrosive liquid should only be stored in approved materials like high-density polyethylene (HDPE) or stainless steel.

Don't put D.E.F in packaging of plastics with additives or non-ferrous metals & their alloys and carbon steel.

The SCR system will recognize solutions other than D.E.F, and the D.E.F indicator light will appear notifying the driver.Depending on the level of contamination in the tank, the vehicle may require servicing
