CRT® System - Continuously Regenerating Trap


The Eminox Continuously Regenerating Trap (CRT) system is the world’s leading retrofit diesel particulate filter (DPF), which is installed on buses, trucks and construction equipment worldwide. It reduces particulate matter (PM) to Euro VI emissions levels.

The CRT® system reduces PM by more than 90% and virtually eliminates Hydrocarbons (HC) and Carbon Monoxide (CO) and is Nitrogen Oxide (NOx) neutral.

The system reduces PM by both mass and number (PN), trapping ultra-fine particles, which are the most damaging to people’s health.

CRT technology has been rigorously tested and is approved for use in Low Emission Zones and E-Zones across Europe, it is also approved by VERT and the Energy Saving Trust.

Eminox filter reconditioning and exchange programmes offer a convenient way to service the filter with minimal vehicle downtime.
