I'm pretty sure any trane scroll was built by Copeland.
Even the name alliance seems to infer this IMO.

The grey painted commercial scrolls are made by Danfos. Most places that sell Danfos compressors will have a crossover list to show which model matches with a given Trane commercial compressor part/model number.
It isn't just a crossover to a similar product, it is a crossover to the exact same compressor, just painted Danfos blue, and usually >20% cheaper than Trane wants for it.If more government is the answer, then it's a really stupid question.

The suction lines probably corrode faster since they will sweat in cooling mode, wetting the salt on the metal. corrosion is an electrical process, and salt water or brine work really well for that.
also, you have copper and steel in contact at that point, so there's galvanic corrosion there too, I imagine. I know there's a plastic seal in the joint, but no plastc ring between the pipe and nut, like on a dielectric union.
Do the compressors have blankets on them or are they exposed. maybe washing the salt off and covering the comps to keep salt spray off will help.
If you coat the fittings, the coating must be 100%, or pitting will be much worse wherever any salt gets throughCol 3:23

Trane has done away with the roto lok compressor fittings on most units as for the alliance scroll its a alliance between copeland and trane ,the only difference is the roto lok fitting and the color .so far they still have the roto lok on the ones i have seenThe governent can not give anything to someone that it has not first taken from someone else

CRC softseal is similar to cosmoline. In harsh environments I paint with marine grade antiseize. Of course your probably not going to paint an entire compressor. Is it possible to keep it in check a little if you constantly touch up paint? What if you saved used motor oil and poured it on comp and roto loks monthly?- ok the last one was a joke.

The only reason I knew that is on back of danfoss catalog was a group picture of all their products and I noticed manuerop recips in the background.
