I have similar problems!

Some web-sites refuse to either work at all or fail to work properly. Sometimes messages appear telling me that I "MUST" upgrade my browser.

The browsers on my computer are the most recent that will work on my Operating System.

As I see it, if a company's web site will NOT work properly with my system as it is, then they will NOT benefit from my business.

I have an Allendale Ultrasonic bath which I bought from their premises in Hoddesdon. When there appeared to be a fault, I took it back and their technician conducted extensive tests while I was there -this was before Covid, of course.

I have always found the people at Allendale very pleasant and helpful.

Just bought an Allendale 3L ultrasonic cleaner. Great service.

Never having used an ultrasonic cleaner before, how loud should they be in operation? Mine really needs ear defenders to stand next to it while it's cleaning.

I assumed it would be fairly quiet, since I definitely cannot hear 40kHz ! but it makes quite a loud buzzing. There are also almost no bubbles produced in the cleaning solution. Should I expect any?

I have emailed Allendale, but just wondering if others could comment on their own cleaners for comparison.

Mine, a generic Chinese type, is pretty noisy whether parts are in a basket or not. And yes, ear defenders are called for if you are close to it. The bubbles are very small, and not produced in large quantities, so I'd say yours is working the same as mine, and mine does what it's supposed to.

In addition to what has already been said:

1. When filling an ultrasonic bath with fresh solution run it for ten or fifteen minutes to 'de-gas' the liquid. Why? I haven't the foggiest, but I worked for a company that sold large ultrasonic baths and this is what the experts recommended.

2. A simple test to see if your bath is working correctly. Place a bit of kitchen foil in the solution and run for a few minutes. You should be able to see a number of pin holes punched in the foil.

I use a cheap bath and it is very noisy.

OK, thank you. Well I am using my Allendale cleaner exactly according to the instructions: Using their cleaning solution, diluted and heated to the instructions, de-gassing the solution, using a basket.

I have done a foil test and a few holes appeared, but not very many.

But I hadn't expected it to be so loud in operation. It sounds to me like a loose transformer element, and I am wondering if one of the 40kHz transducers is loose or something?

For what it is worth my Walker Industries ultrasound (10'x4"x4" approx) produces 46DbA at 10inches …according to the app on my I phone. I suspect JD2 that there is something wrong with your unit.
