    Exclamation

    chiller runs great as long as you can keep the engine running, we don't work on the cat engines just the chiller so we have to call in ransom on about 90 % of the service calls.

    The biggest downside of the YG's besides the extremely maintenance intensive part on the CAT itself is the fact that the "Absolute" maximum entering condenser water temp allowed is 85f on all the YG's. There was one huge one located at the Pentagon with a monster 3600 series engine with 4000hp on natural gas where we modified the turbocharger heat exchanger to chill water as opposed to the standard condenser water and it worked great..
    Too bad they all were not modified for this as it ain't always possible to obtain 85f condenser water....

    How do you measure shaft load? We use a torque meter and have nothing but problems with it. We use river water, so we have issues with cold cond. Water and not warm...

    Shaft load (Engine Load) on all the YG's from York is calculated from the Turbo-Chargers boost pressure. A 15 psi boost signal(29.5psia) is normally set as a 100% engine load while a 14.7psia signal (No Boost) from the intake manifold is set as 0% load. The true boost pressure is actually engine specific but 15psi boost is very close on all the Cat drives. The YG's Luv' cold condenser water and run very well with entering condenser water as low as 55f.
    The Cat drive York chillers (YG) are no longer made at the Caterpiller plant in Lafayett Indiana, but will now be made at the York Pa. plant.

    Our engine load calculates from a bensfield torque meter. We are looking into changing it to run off of manifold pressure. Te torqu meter we have now uses a strain gauge that is secured to the shaft and uses a transmitter to send the engine ecm a signal to load up or down. The transmitter rotates with the shaft and always breaks.
