## Overview

NuDEF Diesel Exhaust Fluid Additive & Stabilizer is a high-performance solution designed to prevent DEF crystallization, lower its freezing point, and protect critical SCR system components. Treating up to 25 gallons per bottle, it ensures reliable emissions control and reduces maintenance costs for diesel vehicles.

## Description

NuDEF: A Solution to DEF Crystallization To address these challenges, NuDEF offers a reliable solution. NuDEF is an additive designed to prevent the freezing and crystallization of DEF, thus maintaining the fluidity and effectiveness of DEF even in cold environments. Here?s how NuDEF enhances DEF performance: -Freezing Point Reduction: NuDEF lowers the freezing point of DEF, ensuring that it remains liquid at temperatures well below the typical freezing point of standard DEF solutions. -Prevents Crystallization: By inhibiting crystallization, NuDEF helps maintain a clear path in injectors and filters, ensuring consistent delivery and optimal SCR performance. -Enhanced Sensor Accuracy: With fewer crystallization issues, sensors operate more reliably, maintaining correct DEF dosing and efficient NOx reduction.
