Electronic Service Indicator


An Electronic Service Indicator (ESI) will continuously monitor system back pressure and provide service alerts regarding the Eminox CRT performance.

Eminox CRT® emission systems use diesel particulate filters to trap and remove particulate matter. These filters need to be periodically cleaned to remove any build-up of ash and particulate matter.

By maintaining the filter, potentially expensive filter damage can be avoided.

How the ESI Works

A sensor measures back pressure and a digital display shows the back pressure status.

Green - The unit is on and working correctly.

Amber - The back pressure has risen above acceptable levels and the filter may require servicing.

Red - The back pressure has risen to a critical level and filter requires immediate servicing.

The ESI will display the max back pressure since the last reset.

The digital display will alternate between the current and peak back pressure since the ESI was last reset and will store back pressure measurements, providing diagnostic information that can later be downloaded to a PC for analysis.
The back pressure limits can be tailored exactly to each vehicle thereby ensuring optimal operation and correct servicing of the filter.

Each ESI also comes with connectors to fit optional warning lights in the cab of the vehicle, to alert the driver when filter servicing is required.

The ESI is easy to install and is housed in a robust automotive standard casing and all elements are resistant to vibration, heat and water pressure, so it can withstand the rigours of vehicle operation, maintenance and cleaning.

The filter can be professionally reconditioned using the unique Xpurge filter cleaning technology. Reconditioned filters can be inspected using the Veritex system.
