Particulate emission monitoring is a challenging technical field, not only because of the application specific accuracy and performance of particulate emission monitors, but also due to the harsh environments in which they must continuously operate. To meet these challenges, ENVEA UK produce a comprehensive range of monitoring solutions to meet the broad needs of particulate emitting industries worldwide and the requirements of national and international regulations.

Particulate Measurement Systems

Particulate Measurement Systems provide continuous measurement of particulate emission concentrations which, for a defined range of application conditions, have the accuracy and consistency of response to be reliably calibrated against isokinetic gravimetric test samples (standard reference method). ENVEA UK’s range of approved particulate measurement systems satisfy rigorous standards to meet national and international regulatory requirements. Instruments are also supplied for non-regulatory measurement with similar performance to approved instruments.


Filter Performance Monitors

Filter Performance Monitors continuously monitor and display particulate emissions and indicate relative changes over time to provide valuable feedback on filter plant performance (bagfilters, cyclone filters, dryers, scrubbers). In addition, the ability to locate faulty filter media by row or compartment minimises the need to replace filtration media, reduces labour requirements for fault location and reduces process downtime. This functionality can be combined with Particulate Measurement Systems and ENVEA UK's data logging control units, and where required systems are available with full performance approvals.


Filter Leak Monitors

Filter Leak Monitors, also known as Burst Bag Detectors (Europe) and Bag Leak Detectors (US), track changes in emissions from particulate arrestment plant and provide a tool to minimise emissions and monitor for arrestment plant malfunction (e.g. damaged filtration media). ENVEA UK’s range includes approved Filter Leak Monitors where quality assurance features are required – performance standards are similar to ASTM standard D7392-07 for Bag Leak Detectors and therefore offer MACT compliant monitoring solutions in the USA. Instruments not verified under an approval scheme retain a variety of quality assurance and functionality options.


Dust Gross Filter Failure Detectors

Dust Gross Filter Failure Detectors track significant increases in particulate loadings to indicate failure in the arrestment plant (e.g. gross bag filter failure or cyclone overflow). Gross Filter Failure Detector alarms typically require immediate reactive maintenance to be taken on the filter plant, as there is no pre-emptive warning or early indication of filter deterioration.
