AdBlue — also known as Diesel Exhaust Fluid (DEF) — is a precisely formulated solution of 32.5% high-purity urea in demineralized water. When injected into the exhaust stream of a diesel engine equipped with Selective Catalytic Reduction (SCR) technology, it converts harmful nitrogen oxides (NOx) into harmless nitrogen gas and water vapor.
How SCR Technology Works: 1. The diesel engine produces exhaust gases containing NOx 2. AdBlue is injected into the exhaust stream upstream of the SCR catalyst 3. Heat converts the urea into ammonia (NH3) and CO2 4. In the SCR catalyst, ammonia reacts with NOx to produce nitrogen (N2) and water (H2O) 5. The result: up to 90% reduction in NOx emissions
AdBlue Quality Matters: AdBlue must meet the ISO 22241 standard. Using substandard or contaminated fluid can damage the SCR system, leading to costly repairs. Key quality parameters include urea concentration (32.5% plus or minus 0.7%), metals content, and biuret levels.
Storage and Handling: - Store between -11 degrees C and 30 degrees C - Avoid direct sunlight and contamination - Use only dedicated AdBlue containers (no metal contact) - Shelf life is approximately 12-18 months when properly stored
Consumption rates vary by vehicle and driving conditions, but typically range from 3-5% of diesel consumption. A truck consuming 30 liters of diesel per 100 km will use approximately 1-1.5 liters of AdBlue over the same distance.
Our i-GlooOil AdBlue meets ISO 22241 and VDA license requirements, available in 10L, 20L, 200L, and 1000L IBC containers.
