I'm looking for buying advice on an ultrasonic cleaner. Our shop overhauls
several regulators a week so we don't need anything that can clean more then
one 1st stage, 2nd stage, and octo at a time. I would like any advice on
brand, model (size), and accessories that you can give me.

Thanks,
Al

I got a used from from my dentist, for free. Had a minor
electrical fault, which cost me 15 minutes to repair.

I've never used anything but Branson, and they just always work like
they're supposed to. I have a .75 gallon one at home. I usually do two
first stages or 2 second stages at a time. We had a similar one at a
very busy reg repair shop in SC, and I always wished it was bigger, but
we did 5-20 regs a day.

Political Correctness is a doctrine fostered by a delusional minority
and the mainstream media, which holds forth the proposition that it is
entirely possible to pick up a turd by the clean end.

I am a real big fan of the L&R 2014.  It is the right size to put the
stuff in you need, is powerful enough and, with the right chemicals,
cuts through the toughest crud.  It isn't cheap though ... about $550
although Global sells them for $800+.  I don't use the basket or cook in
the main pan.  I have a plastic tub that I put the chemicals in and
submerge it in the stainless steel tub.  The waves are transmitted to
the inner tub and cleans there.  That keeps the cleaner from getting
crudded up with silicone, salt and debris.

Good hunting!

Thanks for your advice, the Branson and L&R brands are at the top of my list
and I did have someone in a local shop recommend "Crest". The Branson that I
am considering is the .75 gal model, I'll have to do some web surfing to
find the capacity of the L&R unit. I'm a "toyaholic" so the tough part will
be to buy the right size and not something I can fit a fully assembled V8
engine into.

Thanks again,
Al

Al,

Crest Ultrasonics is here in NJ.

Regardless of the brand/size you select, you should have a look on eBay.
I just picked up a brand new (drop shipped from the factory!) Crest .75
gallon unit with digital controls, basket and lid for under $400. The
best price I've seen for the same unit elsewhere was over $500.

I think a .75 gallon unit will be marginally enough for a first and two
seconds simultaneously, especially if you clean the second stage
housings in it. Depends a bit on the form factor. The Crest is a little
shallow with the basket, and the instructions say to _always_ use the
basket. Maybe you should look into a 1.6 gallon.  Don't get one _too_
big, that will just be a waste of cleaning solution (you can't run them
partially full).

I didn't know that you could clean plastic parts in an ultrasonic cleaner,
what do you use for a cleaner?
I've been told to use plain water with a small amount of dish soap in the
main tank and use plastic or glass containers for the different cleaning
solutions placed inside the main tank.

Water with a few drops of dish soap. Don't leave plastic parts in the
ultrasonic cleaner for very long, they'll start to look bad (I think the
word is "craize"). A few minutes should be sufficient - plastic doesn't
get as nasty as brass, usually. If your ultrasonic cleaner has a power
control, turn it to minimum.

I've never done that. I just put the parts into the basket. I can see
where using a small container would help with very small parts (like HP
air spools). As long as the sound (pressure) waves make it through the
containers, it should work. In that regard, I'd expect plastic drink
cups to be better than glass. I'd be a little concerned with glass
braking, too. You still need to make sure the tank is filled with a
liquid to the proper depth. If you're not cleaning anything directly in
the main tank, the dish soap is probably not necessary.

I was told by several shops that the strong (acidic cleaners) would attack
the main tank, that's the reason I was given for using water with a small
amount of detergent in the main tank and other containers to hold the harsh
cleaners inside the main tank.

Over time, a strong acidic solution might destroy the stainless steel tank.

But you don't need to use a strong solution. If you don't let your gear
get completely crudded up, you probably don't even need to use an acid.

The L&R 2014 is the same size ... 3 quarts

Thanks for the information Ray. I've been busy trying to get my truck
running, it caused me to miss a dive on Sunday, and haven't had a chance to
look for that info myself.

Thanks for your time,
