Xenum ADMAX AdBlue® Additive

The economical Xenum ADMAX is an AdBlue crystallization inhibitor.

ADMAX effectively prevents AdBlue from crystallizing and protects the SCR system from damage.

Keep your system working all year round, prevent nozzle clogging and reduce NOx emissions.

An exceptionally economical 1:500 concentrate – one 250 ml bottle treats up to 125 litres of AdBlue.

Why choose Xenum ADMAX?

• Economical: the 1:500 concentrate goes considerably further than many competing products
• Helps prevent crystallization: the product is designed to prevent crystals from forming in the SCR (Selective Catalytic Reduction) system. This is especially important when exhaust temperatures stay low, for example on short trips.
• Protects nozzles and pump: helps keep the AdBlue nozzles clean and prevents them from clogging.
• Improves system performance: speeds up the conversion of urea into ammonia, which improves the efficiency of the SCR system and reduces nitrogen oxide (NOx) emissions.
• Extends SCR catalyst life: protects the exhaust system from corrosion and prevents the catalyst from clogging.
• Storage protection: helps preserve the properties of AdBlue even when the vehicle stands unused for longer periods.

Instructions for use and dosage

ADMAX is a very economical concentrate that is added directly to the AdBlue tank (not the fuel tank!).

• Dosage: 1:500.
• Use: add 25 ml of ADMAX before filling up with AdBlue. This amount is enough to treat up to 12 litres of AdBlue.
• Bottle: the handy dosing bottle makes measuring easy (250 ml bottle)

The product is compatible with all diesel vehicles equipped with an AdBlue system.

The most common AdBlue system problem

The AdBlue systems of modern diesel cars are sensitive to faults.

Xenum ADMAX has been developed to solve the most common of these problems: urea crystallization.

When the exhaust temperature is low (for example on short trips), AdBlue tends to form crystals.

These crystals clog nozzles, pumps and the cells of the SCR catalyst, leading to engine warning lights and expensive repair bills.

ADMAX keeps the system cleaner and improves reliability.
