This application is very demanding on ultrasonic cleaning equipment, and a number of systemsfrom other manufacturers failed. With poor reliability and inadequate backup there was ongoing frustration for our client, who asked N.T.S. Ultrasonics Pty Ltd for a new cleaner designed specifically to handle the workload.
