    American Standard "Tonrac" chillers

    Some of the old timers in the chiller business might remember the TONRAC chillers. An interesting point about these machines is the name itself. When this unit was being developed they needed a name, and it was decided that the perfect name would be the perfect refrigeration cycle spelt backards. Therefore the CARNOT cycle spelt backwards is TONRAC. This is just a point of interest to you chiller folks. It is good to see a Chiller form.

    Before my time, but I found an old thread with some pics of one.

    It looks like the Trane PCV may have been loosely based on it's design.

    I have a few moth balled ones around. Was one of the first centrifugals I serviced.
    Your poor planning does not constitute an emergency on my part!!!!

    Hey stickerhead,
    Have seen both chrysler (Trane bench-grinder mounted on top of shells and old Worthington I think she was rated at 200tons but was apporx. 20ft*15ft foot print with 8ft tall open drive old school motor with commutator ring and brushes exposed), but what's a spoolie? 19c maybe? Maybe I should ask Tim Mc...

    Tonrac

    Didn't you guys see my pics of an old Tonrac? We changed one out a few years back, the other still sits there. My first chiller call out, R113 chiller at atmospheric pressure, and a huge puddle of oil, leading right to a split bellows. A local machine shop replaced the brass bellows on the assembly, ran the purge overnight, started her up three days later. Ya gotta love low pressure.
