AdBlue® Shelf Life

AdBlue Shelf Life

Temperature control inside the AdBlue® tank

In some parts of South Africa/Africa where the temperature is extremely hot, we have solutions to install a fan to cool down the AdBlue® inside the AdBlue®tank. Our AdBlue® tanks are fully bunded and if the AdBlue® tank is kept away from direct sunlight in a warehouse, the environment should be conducive enough to reduce the temperature of the AdBlue® inside the AdBlue® tank and maintain the ISO 22241-3 standard.

Cleanliness of surfaces in contact with AdBlue®

All surfaces of handling, transportation, and storage equipment in direct contact with AdBlue® shall be free of foreign matter (e.g. fuel, oil, grease, detergent, dust, and any other substance). To avoid any contamination of AdBlue® with trace elements, particles, and foreign matter, surfaces of equipment not exclusively used with AdBlue® shall be cleaned with distilled or de-ionized water and AdBlue® in the last cleaning step immediately before the use with the AdBlue® to be handled with the equipment. AdBlue® storage tank must be always kept clean and kept in good conditions.

The use of water should be avoided

The use of tap water should especially be avoided due to the high concentrations of alkali and alkali earth metal ions therein. However, if distilled water or de-ionized water is not readily available, the material may be cleaned with tap water, provided the last rinse is done using the AdBlue® to be handled with the equipment. If it is necessary to clean a system regardless of whether detergents are used or not, it should be verified that the trace elements specified in ISO 22241-1 in the AdBlue®that is used for a last rinsing are within the specification using the methods specified in ISO 22241-2. For storage and transportation facilities, the result of the cleaning can be verified by analysing the AdBlue® used for a last rinsing using the methods specified in ISO 22241-2
