PROCARE TMDRIVE Remote Telematics

The Proventia ProCareTMDrive is a compact device that continuously monitors the performance and operation of the system providing real time emissions data. Engine out and Tailpipe NOx are monitored and logged enabling NOx reduction to be calculated at any time. DPF back pressure is also monitored along with catalyst and DPF temperatures.

Coupled with location tracking it enables the operator or authority to monitor the performance of the vehicle. All data is available in spreadsheet format to enable whole fleet data to be collected and analysed. All software is developed in house enabling custom reporting to be offered for large fleets.
