E-Coil Manufacturer Logos

Sometimes it can be challenging to determine who the manufacturer is for an evaporator coil from the label, when all you have to go by is a logo and model number.

Thought I would post a couple common ones here for reference.

The first attachment (A/M logo) is manufactured by Aspen Manufacturing. Older unit with a pre-2000 serial number schema

Not sure who the manufacturer is for the second unit. I have heard that it is an older Aspen Manufacturing logo and ALSO Alpine, but I don’t know. I would appreciate it if some in-the-know would post the manufacturer name (please only post if you’re sure - don’t guess).

Also if anyone has other examples of e-coil labels that have logos but no names, please post em up with the manufacturer for future reference.
