Eminox CRT® and SCRT® emission systems rely on diesel particulate filters to maintain their particulate matter reducing capability. These filters need to be periodically cleaned to remove any build up of ash and particulate matter.
The Electronic Service Indicator (ESI) is designed for use with both the CRT® and SCRT® systems. It continuously monitors system back pressure and indicates when servicing of the filter is necessary. By monitoring the performance of the system, expensive filter damage can be avoided.
The ESI has two key parts: a back pressure sensor and a microprocessor. The sensor measures and sends back pressure readings to the processor which incorporates a digital display and a series of three warning lights.
The ESI will display the Max back pressure since the last reset
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 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.
When the ESI indicates filter service is needed we recommend a professional cleaning service such as Eminox Filter Servicing, which will help maintain the service interval. ESI, combined with the unique Xpurge filter cleaning technology we use, is a cost effective way for operators to safeguard their investment and ensure they meet their environmental targets. Monitoring a system's performance and filter condition using ESI is quicker, cheaper and less disruptive than comparable systems and can be carried out as part of a driver's daily checks.
We recommend that an ESI is fitted with all CRT and SCRT systems. Systems fitted without an ESI can be upgraded to add this valuable system protection.
