Any knowledge of industrial ultrasonic cleaners?

The big chassis is about 14 x 17 inches and weighs about 60 lbs. The two large transformer looking objects have two wires and are apparently the largest chokes I have ever seen.

I have two of these. One table w/two tanks, two little boxes (filters), two big boxes, apparently ultrasonic generators. Plugged a filter into mains, cabled to generator, all I can observe so far is fan doesn't come on.

They are all marked Westinghouse. So far, no Google results except to find that Westinghouse developed ultrasound in the 50s. The last indicated patent was granted 1965.

Any input appreciated. I put this in Clubhouse since it isn't radio. Sorry if it is inappropriate.

Don't test the generator on empty, unless you don't mind breaking it anyway.

Thanks, Nick, there is a warning on the tank not to do that. The ultrasound transducer (?) is in the tank, which has a mains cable and a nine pin connection to the generator.

If it is "ultra-sonic" it is just barely above the audible range. The active power device is a thyristor and back in those days, it was hard to achieve much above 10 KHz, unless this system tuned to a harmonic.

Also rather low power, as it hooks to 115V AC mains. Probably under a KW. Back in those days, I think the transducer was magneto-strictive rather than piezo-electric.

Probably made in Sykesville, MD, though it could have been made in Buffalo. I worked for Westinghouse (Semiconductor) from the late 60s.

Rich, thanks for your help. Are there any tests I can do from the 9 pin connector which will verify if the transducer is working? The heater in one tank is working, but this is not any help. The generators have a power switch which is also a breaker, and if I hold the switch on, it just opens a mains breaker. One filter passes current to a generator, whether it filters or not, I don't know. I am guessing shorted caps in the generators.

My dad worked for Westinghouse in Bath, NY, receiving tube plant. I later worked there after it was sold to Philips Lighting.

Thanks for any help,

Bill
