- Easy to use, on-screen prompts, minimal (<10min) training required
- Designed to handle the rugged demands of mining sites
- Auto-generates & displays Stall or Free Acceleration test results
Reliable, Effective
The DPM is the tool that mechanical and workshop staff need in order to reliably identify high DPM emitters, and to validate the effectiveness of emissions-related maintenance.
Accurate Measurement
The rugged, practical and easily operated DPM analysis instrument was specifically designed for measuring particulate concentrations in the exhaust of mining engines. Using advanced laser light-scattering technology, the Enerac DPM unit can accurately and instantly measure particulate mass concentrations in the exhaust from all engine types.
The instrument is highly automated, with only a single press-button required to initiate and run a test. It is designed for ease of use by maintenance personnel as an everyday workshop tool, after only minimal training, but retains the flexibility to support more complex research or investigative activities.
Routine maintenance of the Enerac DPM unit is limited to checking and periodically replacing one disposable filter.
The Enerac DPM has been pre-programmed to measure particulate mass emissions during a Stall Test or Free Acceleration Test in as little as just one minute. Internal software guides the operator through these standardized DPM test procedures, collects and processes the test data, and automatically produces an overall result immediately once the test is done.
The level of particulates in diesel exhaust is a very important indicator of engine and injector system health. Accordingly, reliable identification of high polluters and validation of repair effectiveness is essential.
Traditional methods, such as measurement of smoke opacity, have been shown to be significantly inferior to the laser light scattering technologies employed in the Enerac DPM. The Enerac DPM unit can detect and measure concentrations of particulates with a nominal diameter down to less than 100 nm (0.0001mm)
Recent advances in mine safety and occupational hygiene have resulted in a large number of diesel vehicles and plant being fitted with particle filters. These filters, when working correctly, greatly reduce particle emissions, so it is essential that their efficiency can be periodically checked. The Enerac DPM unit provides the capability to perform these checks quickly and accurately.
