    Definitely brings back memories, as those were standard fare components during my years in the field. And they weren't cheap either.

    Seems like most of the rack manufacturers were partial to the Precision gang timers, and the Paragon's were in the minority.

    With the Paragon you could replace an indivudual station, whereas the Precision was a single unit. Once a station failed, if you didn't have an extra station on another gang timer you had to replace the entire thing.

    Worked quite funcionally as a timer for my sprinkler system.

    Those are old SORIT valves too, with the coils located on the side of the pilot assembly.

    Talking

    Those paragon clocks are the norm for some stores up this way haha

    i was thinkin it was from 80's too as those old SORIT's only came around in early/mid 80's didnt they?and they went greyin colour in late 80's early 90's

    Pic #5 show the manufacturer as Triton. They were a small, custom rack builder on Long Island who specialized in those belt-drive systems. That rack must have been built around 1985 or so...as a guess.

    They did a nice job from what I saw back then, but they went out not long after because of the competition in the Atlanta area from Phoenix, Margeaux and the new custom rack shops from Hussmann, Warren, etc.

    This was very normal to see in Connecticut. Those Triton racks were popular here. They are very easy to work on and run very well. Dont let the belt drive mess with you and fucus on a contactor and compressor.

    Unloaders are closed by oil pressure so always monitor oil pressure and verify they run loaded.

    Worked on rack systems way back in the apprentice days. Learned alot very quickly. Moved back home and started up my own shop but there's nothing that big here in one package. Forgot alot too. Still got an old Frigidaire belt drive running a walkin freezer for a dog racing friend. Showed him how to keep things clean and how the sightglasses should look. Gave him a maintenance schedule ( don't leave the compressor off for extended periods etc.) Haven't gotten a service call from him in quite a while. Belt drives were a strong way to go just a little more watching needed.

    Yesterday I came across another interesting rack made by Melco in NJ, I have worked on old Melco RTU's but I did not know they also venture into supermarket refrigeration.

    I did, belt driven. It was in old Alpha Beta in Santa Ana, maybe Anaheim.

    the old Melco rack, looks like the pigeons found a toilet in that compressor . I'm used to see separators and oil return floats in all racks, not in this one, I wasn't there long enough to figure the oil return arrangements but Steve Esslinger once said "when the refrigeration piping is sized right an oil return system is not needed" maybe they size everything by the book here
