    "That's a thread in and of itself, really, but Koolgas used "warm" vapor off the top of the receiver rather than hot gas from the discharge. Worked OK as long as the piping runs weren't measured in miles.."




    Dave, here is that thread you mentioned. The floor is all yours...

    Hussmann Koolgas..........

    The name "Koolgas" is a registered trademark held by Hussmann. The original patent, which typically run for 17 years, surely must have run out by now as I remember Koolgas on the Hussmann "New System" back around 1970.

    Leave it to Hussmann to patent the letter K-

    the K is on backorder for another 3 weeks..."

    pretty simple. Something like this can be better taught in front of a rack. You got to see the differential valves and watch with a set of gauges and it will be forever in your head. Simple process.

    Yeah. I'm here, but my weekend plans didn't pan out to well. I went in to help the oncall guy this morning at 7 am and just got home.

    I promise to help with this problem, just when I have a clearer noggin than right now.

    If I tried to explain it at this point, I'd probably only serve to confuse people. I could go back out and work on one, at the moment, without a problem, but the koolsurge valving in my head isn't making a lot of sense. Worst part is, I just stood in front of a vintage 1981 Plus right after lunch today, thinking about this thread...

    And, I haven't made it to a functioning atron with my camera yet, either...

    Stay tuned and please be a bit patient while I recover from my weekend "off". LOL.
