DEF in 210 Litres Barrel

• It is an after treatment technology that treats exhaust gas downstream of the engine
• Main purpose is to reduce level of NOx emitted from engines
• Small quantities of DEF is injected into exhaust upstream of a catalyst, where it vaporizes and decomposes to form ammonia and carbon dioxide
• The ammonia (NH3) is the desired product which in conjunction to the SCR catalyst, converts the NOx to harmless nitrogen (N2) and water (H2O)

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.

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

If product states its DEF and has the ISO 22241 then it is a verified product.

DEF manufacturing has strict requirements and the purity of ingredients is critical to the proper functioning and longevity of the SCR system.

A wrong solution could damage the SCR system and cause issues in functioning of it. Hence it is advised to buy DEF from a certified manufacturer.

For more information about the quality standards, refer to ISO22241 which details specifications for DEF quality, handling, testing, transportation storage, and refilling.

Recommended storage temperature for DEF 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, AdBlue® tanks should be insulated or stored under shade with proper ventilation

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

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

Make sure to carry some emergency supply along with the vehicle to reach the next DEF 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 DEF in packaging of plastics with additives or non-ferrous metals & their alloys and carbon steel.

DEF is corrosive in nature hence for storing do not use corrosive materials like copper, nickel, zinc, mild iron or aluminum.

Do not use old diesel or oil containers or equipment to transfer DEF into the tank. Dedicated equipment should be used to handle AdBlue® as even a small contamination of fuel/oil/lubricant can damage the SCR system of the vehicle.

By mistake if DEF is filled into the diesel tank or diesel is filled in the DEF tank, it is advised not to start or move the vehicle. The tank will need to be first drained in such a situation.

The SCR system will recognize solutions other than DEF, and the DEF indicator light will appear notifying the driver

Depending on the level of contamination in the tank, the vehicle may require servicing
