    don't know. the wheel wasn't pitted like carry over. the boys in the chiller forum surmised metal fatigue.
    and Bret, Art, it is the impeller out of a single stage, 1000ton york OT centrifugal. The wheel was $30k, and it was repaired around the clock, took 8 days, 2 men per shift.
    The machine had vibration, the perferred mechanical contractor said the isolation springs under the machine were worn out and needed replacement. (hahahahahahahaaahha)

    Not positive. A cooler is a refrigerant flooded vessel, and between the impeller and the refrigerant are usually baffles to minimize liquid carry over into the impeller eye. Carryover etches the wheel, kinda like sand blasting. This one wasn't a victim of that. Neither were this one, brand new, hand grenaded before machine came up to speed, and took out the second wheel and the casting These are approx. 4' in diameter, 40k apiece, and difficult to obtain (8 months) due to age of machine and the fact this country doesn't build anything anymore.

    WTF do you do while waiting for parts?

    Obviously, the machine cannot run. With an 8 month wait, what happens to the process that the machine was designed for? Is there a 'back-up' machine or a portable type that can be brought in or is customer just S.O.L?

    My customers scream when something can't be brought in within a weeks time. I can't imagine what a manager would say if I told them it was an 8 month wait for a compressor!

    Morning JP.
    Machine hasn't run in 3 years due to manufacturing problems. Machine is a heat recovery, so, it is able to run all year round. It's for comfort cooling/heating. Yes, it has back up.
    And, I can't understand, plaese try to explain this. It can produce about 110,115 degree water, which is enough to heat in chicago, where design is 0. They have back up electric water heaters. Electric heaters are more costly to use, from what I've been told. Elecrtric water heaters are more efficient, I would think, being able to get 100% out of it, where spinning a machine that uses energy to compress freon, and then heat transfer to water, AND those motors were designed in the 40's, which makes them energy hogs,. somehow my abacus doen't carry over enough decimal points to make sense.
