Leak Detection bubble mix
Any one got a good recipe for leak detection bubble mix, I can't make one as good as the commercial ones but they are so expensive?

Re: Leak Detection bubble mix
Hi!
we manufacture a Leak control System, that controls thermodynamic parameters from the installation and sends a sms to the installer when detecting the leak.
For locating the leak, we recomend the use of a good ultrasound equipment. that will safe a LOT of time for you

Re: Leak Detection bubble mix
any liquid soap should work mixed 20/80 with water you should make sure that the liquid soap doesn't contain salt or ammonia as this can cause problems with copper pipework and brass fittings

Re: Leak Detection bubble mix
if you add 10% glycarine oil to mix and leave in fridge overnight it makes better bubles

Re: Leak Detection bubble mix
If you rely on bubble mix for leak detection, you have rocks in your head.
Break the bank and buy an electronic leak detector. So long as you can read the operational instructions.
Cheeez.

Re: Leak Detection bubble mix
Electronic devices are not normally the best solution. Seriously, ultrasounds technology allows you to find leaks even in vaccuum, as they catch the ultrasound of the turbulence of ANY gas scaping, or entering the circuit. We've experienced great results with this technology.

Re: Leak Detection bubble mix
I realise electronic detectors are the go I have the top of the range TIF but it isn't the best way to pinpoint the exact area, and useless when nitro testing the system.

Re: Leak Detection bubble mix
Hi cma
You are very correct. I use two top of the of the line electronics to find the location, then a buble test (big blu) for exact spot. Once found I will spray with flourescent spray paint a circle around it - because usually the customer doesn't pay for it to be fixed straight away.

Re: Leak Detection bubble mix
as mentioned... ultrasounds take you to the exact point of the leak, without any intrusive method, or getting dirty the system...

Re: Leak Detection bubble mix
Big Blu is by far the the best but as you say expensive . It will show leaks that soapy water won't .
The glycerine theory by Tesla is worth a try though .

Re: Leak Detection bubble mix
Sorry for dragging on this post but I forgot one other important tip. If a leak is suspected from loss of gas but the leak cannot be located this is the method I was taught.
Seal suspected areas or components with a plastic bag and tape. Come back in a few hours or the next day and cut a small hole at the bottom of bag, then insert tip of electronic or hose of halide detector to confirm leak.

Re: Leak Detection bubble mix
it seems you all like spending days in finding a leak... with ultrasounds, you can find it in a matter of (a few)minutes in the 90% of the cases

Re: Leak Detection bubble mix
spray n wipe works for me,but if leakage is large it usually gets blown away.then the finger and suds go together,have had to this with off the shelf stuff as well

It's better to keep your mouth shut and give the impression that you're stupid than to open it and remove all doubt.

Re: Leak Detection bubble mix
electronic leak detecors are great unless you are in confined spaces.. then the blasted thing just Bleeps all over... reset sensitivity, try again, still bleeps all over or doesnt bleep at all...
I like bubbles for nitrogen leak testing.. (pump the system up to full design pressure).. if I have a pesky leak I'll introduce some UV Dye in it and then go at it with a UV light at night... leak almost always shows up then...
I use a bit of washing machine Soap, some dawn dishwashing liquid and water.. about 70% water, 30% soap seems to work well...

Re: Leak Detection bubble mix
Hi there!
the ultrasonic leak locator device is not mine.
I am not a refrigeration engineer, but I live among all you, and I try to sell special and very technical tools for our industry. So, I decided to enter this forum and learn sth, as one of my goals is to grow as a person and as a professional. I've used it many times, and have found leaks that engineers were looking for for several months.I don't want to be "too commercial" in the forum. The brand is Ultraprobe, it is an American device, and my company distributes it in Europe. What I can tell you, from the practical point of view, is that I use to travel around Europe with it, but I never come back to Spain with it in my hands. After a couple of demonstrations, I normally sell it.
There are many videos in internet about it, our you can go directly to the manufacturer. we also organize training courses to learn (ourselves included) about the ultrasounds technoclogy, which is quite new by the way.
Sorry for the "brick" (Spanish expression for such a long answer)Last edited by Fri3Oil System; 03-05-2010 at 09:59 AM.

Quite new ? I have mine since 1990 , an SDT

Re: Leak Detection bubble mix
Quite new, specially in Europe.
Regarding the leakages, it's also quite new... You can check how many guys here use it.
They started 1973, so it is quite relative deciding how new/old it is. 40yrs experience is quite nice time to develop a technology.
I don't know that model, if it's the same manufacturer, probably its not the most accurate now, you should buy a new one :P
kind regards

Re: Leak Detection bubble mix
SDT is not a model but the inventor of the ultrasonic.
Anyhow, used already brand new ultrasonic systems and they can't compete the sniffers, not even the cheapest ones.It's better to keep your mouth shut and give the impression that you're stupid than to open it and remove all doubt.
