It was a well built bugger. Brass volute, all controls under the hood, connect sensors and run. True, it had some longevity issues.

    Cool! The early days of radiant and injection loops? 

    And same as @kcopp 24volts ac or dc? Why?

    Shows both AC and DC input, it came with a large 120- 24V transformer.

    As I recall this manufacturer attended a RPA event and asked what the industry need, came back with this solution. It was when injection mixing was popular.  If you run into Ted Lowe with NTI, he was involved with promoting this circ.

    I had some success with this circ. I designed quite a few systems with it. I thought it was pretty cool at the time!
