## Description

WYNNS Ad-Protect pour Adblue®- Prevents Costly System Repairs & Adblue® Crystallisation - Keeps SCR System Clean & Efficient - Enhances Component Lifespan - 125ml

## Features

- ✅ PREVENTS COSTLY REPAIRS BY AVOIDING CRYSTALLISATION IN THE ADBLUE SYSTEM: Formulated to prevent the formation of harmful crystalline deposits within the AdBlue system, ensuring the proper operation of the Selective Catalytic Reduction (SCR) system. By maintaining optimal fluidity and preventing obstructions, this treatment helps to avoid expensive repairs caused by crystallisation in key components such as the AdBlue tank, pump unit, and injector. Keeping the system clean ensures that costly breakdowns and disruptions are avoided, ultimately reducing downtime and unexpected maintenance expenses.
- ✅ KEEPS THE SCR SYSTEM CLEAN AND IMPROVES ITS OVERALL OPERATION: Designed to maintain the cleanliness of the Selective Catalytic Reduction (SCR) system, this treatment ensures that AdBlue flows smoothly through all critical components. By preventing the build-up of harmful residues, the solution enhances the efficiency of the SCR process, enabling optimal reduction of nitrogen oxide (NOx) emissions. A clean system supports a consistent injection process, leading to better fuel economy and lower exhaust emissions.
- ✅ ELIMINATES BREAKDOWNS CAUSED BY ADBLUE CRYSTALLISATION AND PROLONGS COMPONENT LIFE: Engineered to dissolve light crystallisation and protect against the formation of new deposits, this AdBlue treatment prevents system failures and extends the life of essential components. Crystallisation can cause blockages and damage to injectors, pumps, and sensors, leading to costly repairs and operational downtime. By incorporating this solution into routine vehicle maintenance, the risk of performance degradation and system malfunctions is minimised.
- ✅ CLEANS ALL CRITICAL COMPONENTS WITH A POWERFUL DISSOLVING EFFECT: This formula delivers a targeted cleaning effect on key elements of the SCR system, including the AdBlue tank, pump unit, and injector. By dissolving light crystallisation and preventing residue accumulation, this treatment ensures uninterrupted AdBlue flow and optimal system function. The powerful cleaning action supports precise dosing and efficient NOx reduction, which is essential for meeting emission standards. By actively keeping the system clean, the product enhances the durability of AdBlue components and safeguards the performance of diesel engines fitted with SCR technology.
- ✅ COMPATIBLE WITH ALL DIESEL EXHAUST FLUIDS AND HIGHLY EFFECTIVE IN SMALL DOSES: Designed to work seamlessly with all recognised Diesel Exhaust Fluids (DEF) and AdBlue solutions, this treatment provides broad compatibility across different vehicle models and SCR systems. A single 125ml bottle effectively treats up to 15 litres of AdBlue, making it a cost-effective and efficient solution for maintaining system performance. The carefully calibrated formula ensures that the treatment integrates perfectly with existing fluids, delivering optimal protection without affecting the integrity of the AdBlue solution.
