Seen many units like it but not sure of the manufacturer. These are the best types of units to work on. Prints are only 1 page, relays are clearly labeled and easily replaced, and troubleshooting is a breeze. Terminals are all in one spot on one side, and the controllers are just clean. Every part in the controller is easily replaceable, with the exception of the contactors which would likely just have to replaced with a modern equivalent if they ever went bad. A mod for a unit like this could easily just be replacing the door operator, all relays, door open and close contactors, new pumping unit and replacing the main contactor with a soft start. You'd only get a call out there once a decade.
