DEF plays a crucial role in reducing harmful emissions, especially in diesel vehicles and heavy machinery. Its application in Selective Catalytic Reduction (SCR) systems has enabled compliance with increasingly strict environmental regulations, contributing to cleaner and more sustainable transportation.

At Noxguard, we ensure that our DEF meets international ISO 22241 standards, preventing the risk of damage to SCR systems and ensuring optimal performance in any diesel vehicle or machinery.

How DEF works in diesel engines

When injected into the exhaust system, DEF reacts with high-temperature gases, converting NOx into nitrogen and water vapor. This chemical process can reduce harmful emissions by up to 90%, helping vehicles meet standards like Euro 6 and EPA regulations in the U.S.

Benefits of using DEF

  • Significant reduction of NOx emissions: Reduces environmental impact and improves air quality.
  • Compliance with environmental regulations: Helps operate commercial fleets and industrial machinery within regulatory limits.
  • Increased engine efficiency: Allows manufacturers to optimize engine performance without compromising power.
  • Cost savings: Reduces fuel consumption by optimizing combustion and gas treatment.
  • Guaranteed quality with Noxguard: Our DEF is formulated to prevent crystallization and ensure the durability of SCR systems.

Applications of DEF

DEF is used across a wide range of sectors that rely on diesel engines, including:

  • Freight transport: Trucks and trailers covering long distances.
  • Public transportation: Urban and long-distance buses.
  • Heavy machinery: Construction, agricultural, and mining equipment.
  • Maritime industry: Diesel-powered vessels operating on commercial routes.

At Noxguard, we ensure a reliable and efficient supply of DEF in key distribution centers and service stations.
