The MDLT-ONE Micro Dilution Tunnel from HORIBA Instruments, Inc. is a compact system designed for sampling particulate emissions using the partial flow dilution method. It operates by diluting a small portion of exhaust with HEPA-filtered air, ensuring a constant flow rate through particulate filters for effective collection of Particulate Matter (PM). The system features high precision venturi flow meters and a piezo actuated valve, which contribute to its fast response time. The MDLT-ONE includes an automatic calibration software that enhances measurement accuracy by correcting flow discrepancies in real-time. Its design allows for flexible installation, with a swivel connection for the tunnel section and the option to integrate an auto filter changer within the main rack, optimizing space efficiency. The system is compliant with various global emissions regulations, including ISO-16183 and Euro VI standards, making it suitable for PM emission measurement across all engine types and for R&D support of engine and after-treatment systems.
The MDLT-ONE is designed to sample particulate emissions using the partial flow dilution method. A small portion of the total exhaust is diluted with HEPA* filtered air to create a constant flow rate through particulate filters to collect Particulate Matter (PM). Compliant to the latest regulations, the new MDLT-ONE is very compact and offers faster response by the use of high precision venturi flow meters and a piezo actuated valve.
*HEPA: High Efficiency Particulate Air
Small package
Heated filter system and flow controllers installed in a single rack. Swivel connection of tunnel section to cabinet allows flexible installation. Auto filter changer* can also be mounted in the main rack for space efficiency.
Automatic calibration software enhances accuracy and ease of use
The MDLT-ONE series performs automatic calibration by flowing air in-series through the two venturi flow meters and correcting any difference to zero in the software. This can be included into an automated sequence within a test template.
Integrated Operating Platform
HORIBA ONE series systems employ a common use interface, “HORIBA ONE PLATFORM” offering future expandability and ease of integration into Test Automation Systems.
