AdBlue Aqueous urea solution is alkaline with feature of non-toxic , non-pollutiing and non-flammable.

AdBlue® Aqueous urea solution has special requirements for storage materials and storage conditions ,because of its alkaline characteristics.

(1) The effect of storage temperature on AdBlue DEF:

AdBlue® requires a storage temperature of about -5 to 25 ℃, it should be avoid sunlight and high temperature. And different storage temperatures with different the shelf life .

The shelf life of AdBlue® at different temperatures is as follows :

It should be sealed immediately and not be used again if there is a strong smell of ammonia when opening the sealing cover of the storage tank,  it can be used after passing the relevant instrument test immediately.

(2) The storage container and filling equipment of AdBlue® ;

AdBlue® DEF will react with some materials, such as copper, iron, aluminum and so on. it will cause the deterioration if it is installed in the pot or the filling equipments of these materials, thus affecting the performance of SCR. So it have to use special equipment for filling AdBlue®. In addition, AdBlue® will crystallize at low temperature and its volume will expand by about 7%. Therefore, the storage volume of AdBlue should be kept at about 90%.

(3)The storage and use environment of AdBlue® should be cleaned.
