3.30 - Multi propellant aerosol leak detection
Tom Hunter, Product Manager, Emerson
As product and customer demands alter, the flexibility of aerosol production lines has become increasingly critical. It is also demanded and expected by many Global brand owners and contract fillers that aerosol lines must have increased automation to guarantee 100% online testing for microleaks, primarily for safety and quality purposes but also to maximize throughput and protect invaluable brand reputation.
With changing end user products, microleak testing devices must therefore look to provide coverage and flexibility for the addition of new propellants whilst also ensuring minimal line downtime between product changes. To achieve this testing flexibility whilst also meeting the increased demand for safety and quality and throughput, Emerson’s Cascade Technologies, the world leader in laser based microleak detection products introduces a step change development, through the launch of a laser based microleak detection device capable of measuring multiple propellants within a single system.
Designed to test 100% of filled cans online from speeds of 60cpm up to 600cpm, this technology utilizes Cascade’s patented Quantum Cascade Laser (QCL) technology.
The development provides a field upgradable, plug and play device where between 1 and 4 lasers targeting specific propellants can be selected and run simultaneously, this ensures that for aerosol fillers utilizing various propellants there is maximum flexibility to test for alternating propellants with no impact on downtime when the fill gas is changed.
This paper will present the patented Quantum Cascade Laser technology that allows Cascade Technologies to achieve this ground-breaking development in the Diamond System.
