Advanced Dispersion and Feeding Systems in Salt Fog Testing
To meet diverse industrial standards and improve the efficacy and accuracy of salt fog tests, the Auto Technology Company has developed advanced dispersion and feeding systems. These enhancements are designed to provide more precise control and uniformity in salt spray distribution across various testing scenarios.
Unifog Dispersion Tower: (U.S. Patent Re-25932)
Complete with adjustable cone for uniform collection rates, salt spray atomizer nozzle, internal reservoir with cover, pick-up tube and filter assembly (number dependent on salt spray test chamber size). For condensing humidity, atomizer nozzle dispenses DI water mist.
ATO-Fill System: (New and improved solution feed system)
Complete with bubble tower automatic feed system for direct DI water feed into the bubble tower from customer supplied plant DI water.
Also includes the Auto Technology 55 gallon mixing and storage tank that feeds directly into the internal chamber reservoir for longer unattended testing time.
Traditional Level Control system is available as an option in place of this system. See page 9 for a description of this item.
