Infrared LEL monitoring systems

The easy to install, low maintenance LEL control system with a fast response time

LEL monitoring systems continually check the level of solvents inside industrial machines’ drying stations, ensuring that they stay well within the law-established parameters. This serves a specific and essential safety purpose: solvents are flammable, and the high temperatures typically persent inside drying stations could well create a fire or explosion hazard. The LEL Monitoring System, where LEL is short for Lower Explosion Level, is capable of controlling solvent concentration so that is constantly below the legal limit. NIRA’s Infrared LEL monitoring systems are particularly suited to the needs of the Tobacco, Pharmaceutical and Food Packaging Industries; they are EC and ATEX certified, and can thus be used even in the immediate proximity of high-risk areas.
