EGR Cooling

EGR Cooling

The function

EGR (Exhaust Gas Recirculation) coolers reduce nitrogen oxide (NOx) emissions by lowering the temperature of recirculated exhaust gases before they re-enter the combustion chamber. This cooling process helps improve combustion efficiency and supports cleaner engine operation.

By reducing combustion temperatures, EGR coolers contribute to lower NOx formation and improved emissions performance. This makes them an essential component for meeting modern environmental standards and maintaining efficient engine operation.

Product Testing & Validation

NRF EGR components, including coolers and valves, are validated to ensure reliable emissions control and consistent engine performance. Coolers undergo dimensional measurements and pressure testing to detect leaks and confirm material durability under demanding operating conditions.

EGR valves are tested using methods suited to their design, including pressure testing, oscilloscope signal analysis, SEM protocols, open/close cycle checks, and voltage measurements. This comprehensive validation ensures accurate operation, stable performance, and long-term reliability across the full EGR product range.

Easy Fit

When a EGR cooling is Easy Fit, all necessary assembly parts (such as gaskets, seals and mounting parts) are delivered in the product packaging. Easy Fit is a great advantage for the workshop, because it ensures an easy and quick installation of the NRF part. With Easy Fit you save time and money, which results in a higher customer satisfaction.
