how do I recognize that the coil had been e-coated?

(OP)
As protective measure against a salt laden area, I have specified the condenser coils to be e-coated.
But I have never seen an e-coated coil before, the question is; how do I recognize that the coil had been e-coated?
 

RE: how do I recognize that the coil had been e-coated?

chemical analysis is one way.

However, the point of the coating is protect your coil, so there should be some sort of test that demonstrates that protection, regardless of whether you can see the coating or not.

RE: how do I recognize that the coil had been e-coated?

First of all, I have zero confidence in any field applied coating, may give you a year longer life than no coating at all.

Factory applied coatings are much better.

It is going to depend on the type of coating being used.

"e-coat" sounds like carrier lingo and a few years back they were coating them with 'electro-fin' and it was black.

"heresite" is a type of phenolic coating that is used it is reddish brown, cannot miss it

"adsil" is a clear coating that is used, so far I like its performance. One way of telling with adsil is there will be a label on it saying adsil or microgaurd certifying that it has been coated and giving warnings about certain cleaning methods not to be used.

So for a definitive method of telling if it is coated or not, talk to the people who make the coating you want used. Is e-coat a generic term or a tradename on your side pof the atlantic.

Hello AbbbyNormal,

Yes, it is Carrier lingo and put on the market by Carrier.

I have attached one document I have about E-coating which is the looks the same a ElectroFin E-coating.

When I have to inspect the stuff I will see if it has a black collour or not, but I think it will be blue as they want it to be blue fin treated.

And for football or soccer, I rather had played the Germans in the final... revenge.
having said that, I have German ancestors.

RE: how do I recognize that the coil had been e-coated?

As AbbyNormal mentioned, it will be very easy to notice. It's quite black, and stands out from most other Al/Cu or Al/Al coils. Just ensure they aren't supplying you with the 'Pre-Coat' option. If you don't mind the extra $, splurge for the E-Coated Cu/Cu Coils instead of the standard Al/Cu.
BTW - I don't see your attachment.

I cannot say I have been impressed with the electro-fin performance

RE: how do I recognize that the coil had been e-coated?

^^^ Capacity issues, or longevity?

RE: how do I recognize that the coil had been e-coated?

electrofin? problem was a lack of longevity when applied primarily to any carrier product
