What is AdBlue


AdBlue, or Diesel Exhaust Fluid (DEF) as it is otherwise known, is an aqueous urea solution blended with 32.5% high purity urea and 67.5% deionized water. DEF solution is used in Selective Catalytic Reduction (SCR) to lower NOx concentration in the exhaust emissions from diesel engines.




SCR Emulator device usage is illegal in some countries, especially in countries of the European Union.


You can legally purchase this item, but in use it will cause higher exhaust gas emissions and your HGV will not meet the EURO 4, EURO 5 and EURO 6 emissions standards which are required in European Union. This product is designed for use in countries where there are no laws requiring EURO 4/5/6 emissions standards. SCR Emulator allows you to stop the DEF (diesel exhaust fluid) supply system in the SCR catalyst, effectively saving you a lot of money on DEF (diesel exhaust fluid) refills . By purchasing this device you take the full responsibility for the use of the device and the associated consequences. It’s your personal decision to use the SCR Emulator or not.


We will not take any responsibility for any consequences associated with usage of SCR Emulator device in a country which requires the compliance of EURO 4/5/6 emissions standards.
