ClearNOx®: Additive-enhanced AdBlue® solution

Prevent SCR crystallisation to improve maintenance

Fleet managers and equipment operators risk costly, unplanned maintenance if their vehicles’ Selective Catalytic Reduction Systems (SCR) stop working properly. To ensure your vehicle runs flawlessly, TotalEnergies experts have created a ground-breaking additive-enhanced AdBlue® solution - ClearNOx®.

Using innovative technology, ClearNOx® expands TotalEnergies extensive AdBlue® range of products formulated to help all types of vehicles to work at their very best.

Formulated with AdBlue®, ClearNOx® works more effectively than AdBlue® alone. Using ClearNOx®, fleet managers can continuously keep the SCR system working as effectively as possible.  

Why choose ClearNOx®?

ClearNOx® is TotalEnergies patented product that is suitable for both on-road and off-road vehicles and equipment fitted with SCR technology. The ready-to-use urea solution has been specially created for SCR after-treatment systems and is compatible with every type of vehicle, including heavy goods vehicles, van fleets, buses, and construction and agricultural equipment.

ClearNOx® prevents crystallisation

• Maintains the SCR system and engine 
• Reduces the number of breakdowns and vehicles out of service in your fleet 
• Manages fuel consumption.

ClearNOx® replaces AdBlue® 

• Is ready to use - no need to drain the tank first 
• Ensures compliance with emissions levels in pollution 
• Controls standards.

ClearNOx® is a trusted, patented product 

• Developed by TotalEnergies researchers 
• An exclusive formula tested in collaboration with engine and vehicle manufacturers. 

By using ClearNOx® and preventing crystallisation, your AdBlue® SCR system will work at full efficiency and will be protected against breakdown and replacement, which could potentially save you up to €3,000*.  

How does ClearNOx® work?

As mentioned, ClearNOx® is an AdBlue® additive solution that is exclusively formulated by TotalEnergies engineers. In certain situations, exhaust gases are not hot enough to react properly with AdBlue® which means it does not completely turn into ammonia. This means that cyanuric acid crystals may form, which would bring a vehicle to standstill and contaminate your engine system.  
 

ClearNOx® complies with the physical and chemical specifications in the ISO 22241 standard, but for optimal SCR system operation, it should always be used after the system has been cleaned at a certified auto repair centre.

ClearNOx® is the solution of choice to reduce your vehicle maintenance needs while helping minimize exhaust emissions. Find out more about AdBlue® or contact our experts for a personalised analysis.  

*The cost of a replacement AdBlue® selective catalytic reduction (SCR) system (purchased and fitted) could be up to €3,000. This is an approximate potential figure as this does depend on a number of variables such as make / model and the type of business they operate within.
