There's a product outhere called High side red epoxy ,(2 part epoxy)much easier to repair small refrigerant leaks & you can use a heat gun. Works great for low & high side it can handle up to 3000 psi Temperature -100 -300 degrees

I'm not convinced about gluing the new disipators, that doesn't seem to be realiable for thermal conduction, seem more like just a cosmetic fix to me. probably doesn't matter considering the overall size of that radiator, but surely matters on small radiators.

Not once have I found a leak in such an easy spot to fix. Most of them don't even have enough space to fit pliers in straight! And believe me, if they aren't parallel with the channel, you will create a leak in the adjacent channel. Have also come across some systems that have leaked out their charge and have been left unnoticed for up to a year, resulting in 5-6 vacuum pump oil changes through the evacuation process to get below 500 microns due to moisture accumulation.. have never had that issue with copper and I've poured water out of copper condensers. Let alone the rate in which aluminum oxidizes compared to copper. Oil changes in hermetic compressors is gonna become a requirement of a p/m contract

Alittle tip for ya --- use dry nitrogen pressure tests and flow dry nitrogen through a unit a few times to Help gather up the moisture. dry nitrogen helps alot ! vacuum for a bit, then dry nitrogen Pressure to 100 psi, then dump the dry nitrogen from the unit, then evac for a bit more . i have flowed a whole bottle of dry nitrogen through systems to pick up the moisture it works good. nitrogen is dry so it grabs onto moisture . speeds evacuation time alot. hope it helps u in the future. dry nitrogen flow while welding also helps make for a fast evacuation time.

I was wondering that myself....also that the replacement fins didn't make contact with the refrigerant tube at the top. But like they said, it's a very small percentage compared to all the remaining fins. I looked up Loctite 430, it says it's especially suited for bonding metal substrates but makes no mention of its ability to conduct heat. I'd rather see those replacement fins a little larger vertically and making contact with the refrigerant tube.
@MelvinIsMerlin5 жыл бұрын

Use thermal epoxy if you want, but don't even need to replace the small section of fins. it's negligible in overall effect.

Often MCHX producer are using automotive design that are very different from HVAC needs. Often MCHX producers are fighting to reduce costs using less and less material. The effect is that MCHX cores are too light, with thin tubes.. easy to damage. To avoid this tipe of leakage is very important to buy from the right MCHX producer.
@EnertechUniversity5 жыл бұрын
Hi there, we are not in the automotive industry, so we cannot speak to what they do. In many warranty situations, we offer to replace the coil. Repair instructions are offered as an alternative due to concerns our dealers had to offer a quick effective repair without waiting for parts. We try to use the best quality products in our equipment. Sometimes damage to coils can’t be helped. MCHX can be repaired using this method.
