Instructions for
Model E992 Passivation
Ultrasonic Washer
Introduction
The Model E992 ultrasonic washer is equipped with three, 30 gallon heated storage
tanks (HST) for alkaline cleaning solution, citric acid or nitric acid solution and
rinse water. Pump filter systems are also incorporated into the HST’s. The
complete system also uses fresh DI water for a final rinse cycle.
The unit is housed in a 304 stainless steel console. The tank is manufactured from
SS 316 with 36 double potting transducers mounted on the bottom. The tank is
fitted with a SS hinged cover, which houses the fans and heaters for air drying.
Inside the console there are 2 Power Module boxes (generators) and the drain
pumps. The Power Modules contain the self-tuning modular circuit boards, high
velocity fans to cool the electronics, and RFI filters to eliminate any high
frequency interference. A control box is mounted on the rear of the console unit
and contains the programmable controller and other related components.
A Beijer HMI panel mount interface is included with the unit allowing monitoring
of the on-line operation and modifying of the program, as well as data collection of
the passivation process.
