Pro-Tec SCR – an effective AdBlue additive without compromising the SCR system

Karol Filarski, Dział Wyposażenia Warsztatu

Modern diesel engines, meeting the stringent Euro 6 emission standards, increasingly use selective catalytic reduction (SCR) technology, which requires the use of AdBlue. AdBlue, a solution of urea in demineralized water, is necessary to effectively convert harmful nitrogen oxides (NOₓ) into harmless nitrogen and water vapor.

However, users of vehicles equipped with SCR systems may encounter various operating problems, such as crystallization, injector contamination or incorrect AdBlue dosing. In response to these challenges, a specialist additive was created - Pro-Tec SCR available in the Autos network in a 5-liter variant (A: 0761134) and a 250 ml variant (A: 0761133 ) , which effectively support the operation of the SCR system without negatively affecting its operation.

Action and application d Additive in 5 liter package (A: 0761134) additive

The main task of this preparation is to prevent urea crystallization , which can lead to clogging of AdBlue injectors and disturbances in the operation of the SCR system. The additive dissolves and neutralizes already formed deposits and prevents their re-formation. Thanks to this, the AdBlue injector works with optimal efficiency, which translates into correct dosing and effective NOₓ reduction.

In what cases is it worth using?

The Pro-Tec SCR additive is especially recommended:

  • When SCR system errors occur due to the AdBlue injector being clogged or contaminated.
  • When AdBlue is unevenly or inefficiently dosed into the exhaust gas flow.
  • In winter vehicle use conditions, when the risk of AdBlue crystallization increases.
  • For vehicles operated intensively or in difficult road and temperature conditions.
  • Preventively – as part of regular maintenance of the emission reduction system.

Safe for SCR system

One of the most 250 ml packaging (A: 0761133) The most important advantages of the Pro-Tec SCR additive are that it does not negatively affect the operation of the exhaust gas after-treatment system . The product does not modify the chemical composition of AdBlue in a way that could disrupt the chemical reactions occurring in the SCR catalyst. It has been developed to interact with AdBlue fluid without violating its quality standards (ISO 22241). Thanks to this, users can be sure that the use of the additive will not affect the vehicle manufacturer's warranty or cause a failure of the emission system.

Pro-Tec SCR is a modern and safe additive to AdBlue that effectively protects and supports the operation of SCR systems in modern diesel engines. Regular use of the product helps prevent costly breakdowns, improves the efficiency of exhaust gas cleaning and supports the ecological aspects of vehicle use. Thanks to the formula developed with compatibility and safety in mind, it is a solution that can be recommended to every driver, mechanic or fleet operator who cares about the technical and environmental efficiency of their vehicles.

Regardless of whether you choose the 5-litre or 250-ml variant, the agent is a very efficient concentrate and just 20 ml of the preparation is enough for up to 10 l of Adblue liquid.
