November 2016 Spray 25 As cans pass under the sample arch, any leaking propellant is drawn into the sample cell where the QLC pulses at high frequencies (up to 100 KHz) in the mid-infrared to identify any released propellant aerosol gases. Software analyzes the resulting concentration profile to identify leaks in real time. Testing all can failure points (valves, crimps, tri-weld and seams), any faulty can will be removed from the moving production line. The system can send an alarm if multiple leaking cans are detected, prompting intervention. The system is certified to perform leak detection on production lines up to 600 cans per minute, regardless of the shape, size or material of the construction. The system offers: • Complete visibility of production data, batch quantities and cans rejected • Tiered security setting for operators and engineers • Reporting capabilities • Data logging for process trend analysis and discrete measurement data • Configuration alarm outputs for seamless integration with existing processes • Easy-automated system level health diagnostics for immediate fault identification and resolution Due to the modular design, the systems support simple upgrades for future propellants and levels of sensitivity. They can be installed as a water bath alternative leak test or in addition to a water bath test. Emerson’s Cascade Aerosol Microleak Detection Systems are fully compliant with all existing industry regulations, including UN ADR and U.S. DOT, according to the company. Spray
