Operational routinely design and install gas and solvent vapour monitoring systems that allow clients to measure LEL (Lower Explosion Limit). Often we use these measurements to proactively control the process, preventing explosive mixtures forming and providing safe shut down alarms where necessary.

Our entire approach is built around delivering intelligent solutions that will improve your overall process performance whilst addressing any specific safety requirements that have been identified.
