ADMAX® PRO: Preventing Crystallisation, Protecting SCR Performance

With stricter emissions regulations and growing demand for environmental responsibility, the pressure on diesel vehicles to meet emissions targets and perform reliably has never been higher. The Selective Catalytic Reduction (SCR) system, which relies on AdBlue® to reduce nitrogen oxide (NOx) emissions, plays a central role in meeting these standards.

While AdBlue® is a reliable solution, the systems that use it aren’t immune to problems, especially in challenging conditions. Cold weather, stop-start driving, and other factors can lead to crystallisation and blockages, which compromise the SCR system’s efficiency and lead to expensive repairs.

This is where ADMAX® PRO can make a real difference. Designed to prevent crystallisation and protect the entire SCR system, it keeps your emissions control system running efficiently, saving on repairs and ensuring emissions compliance.

Prevents Crystallisation and Build-Up

One of the most common SCR issues is crystallisation—particularly in cold weather or during stop-start driving. ADMAX® PRO is designed to prevent crystal formation in the AdBlue® tank, pump, and injector, helping maintain a clear, consistent flow throughout the system.

By keeping these components free from deposits, it reduces the risk of blockages and helps ensure the system continues to function reliably, even in temperatures below –10°C.

Improves Urea conversion to Support NOx Reduction

ADMAX® PRO supports the SCR process by improving the conversion of urea to ammonia, helping the system break down NOx more effectively. The result is more effective emissions control, with fewer risks of compliance issues down the line.

Protects the System, Saves on Repairs

Replacing SCR components can be expensive and time-consuming. ADMAX® PRO helps prevent those issues by keeping the system clean, reducing corrosion, and protecting parts from early wear. It’s a simple step that helps your exhaust system last longer—saving you money on repairs and reducing unnecessary waste. Fewer part replacements also mean fewer resources used and less environmental impact, making it a smarter choice for both your vehicle and the planet.

Easy to Use, Universally Compatible

Each 250 ml dose treats up to 20 litres of AdBlue® and can be added directly to the tank before filling. For regular maintenance, we recommend a single dose every 30,000 km. If your SCR system is already showing signs of build-up, a quick treatment followed by around 1,000 km of driving should restore its normal function.

We recommend using standard ADMAX® with each AdBlue® refill after an ADMAX® PRO treatment to maintain a clean, efficient system.

For Diesel Drivers Who Want Long-Term Performance

ADMAX® PRO doesn’t replace AdBlue®; it enhances the system that relies on it. It's an essential addition to any maintenance routine for diesel drivers looking to reduce emissions, prevent costly repairs, and keep their SCR system performing its best.
