    Ultrasonic Leak Detect for Vacuum Leak

    I've got a CVHE that appears to have a vacuum leak that is proving very difficult to track down. Has anyone had experience with using an ultrasonic leak detector for locating vacuum leaks?

    I have never had any success with the amprobe I have. Maybe yours is better. Likely the size leak is way too small to get a reliable reading. A hot water heater will get you into positive pressure where you can use an electronic leak dectector. Most leak repairs require you to pull the charge. Better to test with nitrogen and trace gas.

    May have to take it to the positive to pinpoint, following manufactures recommendations closely. Alittle to much may be way to much. Good luck.

    I used it on a r113 tonrac which worked locating leaks. sometimes when a system is in a vacuum and you pressurize it then it does not leak while under pressure.

    Rather than wasting your time trying to find it get someone who is familiar with the CVHE to go over it with a set of wrenches and tighten up all the usual trouble spots and monitor your pumpout minutes after that . It will take less time and be more productive .

    Very good suggestion.

    Thanks for the input, it has already been pressurized. I'm thinking we have a vacuum leak that is occurring after the chiller is running for a while. Vac leaks can be difficult to find, they may not show up with pressure. I use a H10, haven't ever had a reason to use anything else. Just wanted to know if the ultrasonic works well for searching for vacuum leaks. Thank goodness this kind of problem only happens once in a while. Keeps you on your toes.
