## Description

Crystal Clean & Protect - Additive for Use with AdBlue© - Prevents Crystal Formation in SCR Systems - Improves Performance of Exhaust Aftertreatment on Diesel Engines - 500ml

## Features

- ✅ HELPS PREVENT CRYSTAL FORMATION IN ADBLUE SYSTEMS: Specially developed for use with AdBlue, this highly effective 500ml additive helps prevent harmful crystal formation in the SCR circuit (selective catalytic reduction). Such crystals can clog injectors, pumps and AdBlue tanks and lead to loss of performance or mechanical damage. By keeping the system clean, this additive protects important components and ensures a smooth and efficient operation of the SCR system in the long term.
- ✅ EXTENDS THE LIFE OF SCR COMPONENTS: Without maintenance, it can lead to slight crystal formation in the SCR system over time – especially for vehicles with high mileage or long idle phases. The advanced formula of this additive actively works against such deposits in the AdBlue tank, injector and pump. Regular use ensures more precise dosing and permanently reduced emissions - for cleaner and more effective exhaust aftertreatment.
- Optimises the operation of the SCR system and improves fuel consumption: a clean and unhindered SCR system allows the diesel engine to function more efficiently and meets the strictest environmental requirements. This additive optimises the flow and injection of the AdBlue system, reduces emissions and supports more economical fuel use.
- Reduces breakdowns and unexpected failures: crystal formation in the SCR system is a common cause of failures and costly repairs on modern diesel vehicles. The preventive use of this additive can significantly reduce the risk of blockages and malfunctions - especially beneficial for fleets, frequent drivers and anyone who needs a reliable vehicle.
- ✅ BULK PACK FOR LONGER USE - TREATS UP TO 60 LITRE ADBLUE: This 500ml bottle has been designed for convenient and economical maintenance - ideal for vehicles with high AdBlue consumption. Compatible with all standard diesel exhaust fluids (DEF) and AdBlue formulations, the additive is easy to apply - simply add directly to the AdBlue tank when filling. For optimal protection, it is recommended to use at every refueling process.
