Refrigerant Leak Detectors

Rich_L

I'm looking for recommendations for leak detectors. Something that can reliably do R-22 and R-410a primarily. Thanks for your help.

I use a

Tif ZX-1, and it works very well.



However I have noticed it works best with cfc's such as r-22. So on trouble 410a units, I reclaim the 410a if there's any left add a trace amount of r22 and pressurize with nitrogen, and this method works very well for me.



Obviously I don't leave the Nitrogen r22 blend in the system.

Thanks

Thanks FF15. Unfortunately that's what I have to do with mine now to find a leak in a 410a or 404 system. I'm wondering if there's anything out there that works equally well on both types of refrigerants?

You can try

You might want to try this one:



Yellow Jacket 10M820



It has three sensitivity levels and I have had great success with it.



One general note on leak detection:



It has been assumed for a long time that, "the only acceptable refrigerant that can be used as a trace gas for leak detection purposes is R-22".



The truth of the matter is that any refrigerant can be used as a trace gas, and the preferable refrigerant should be, therefore, the refrigerant that the system will normally operate with.



Many have, incorrectly, stated that the EPA only permits the use of R-22 traces but the EPA makes no reference to the specifics about which refrigerants are permitted and which are not.



Happy January. Brrrrrrrrrrrrrrrr
