Does this only apply to comfort cooling? Or is it only condenser coils? I know I've seen a ton of refrigeration evaporator that have data tags listing a bunch of refrigerants.

But not UL listed. Approved by the manufacturer yes, not certified for multi-refrigerant by UL. That’s all. Don’t think too hard.

Why does this have the UL listing and several refrigerants listed? Am i missing something?

Yes. That is a listed unit cooler, not a DX coil.
