Ensure every PRD relief event is detected, recorded and reportable.
Updated EPA HON regulations expand monitoring and reporting obligations by requiring visibility into every Pressure Relief Device (PRD) release across a facility. When each event must be detected, timed, and reported, reliance on estimates and assumptions creates compliance risk.
acoustoSENSE delivers always-on, high-frequency acoustic monitoring that delivers accurate, high-resolution data needed for confident HON compliance.
