I have transferred this post from the Chit-Chat section and hope someone can help 'Energy' from the Phillippines.

Good day,
Can any one help me out with some of the problem we had in the field.
We have a Mc Quay Chiller model PEH 087, the unit is a centrifugal chiller. The impeller and the inlet guide vane just melted.
According to Mc Quay the cause is lubrication failure, however when they tear down the compressor, we inspected the high and low speed gear and the gear teeth did not show any wear. Any Idea what the problem is.
Another unit we have is a JE Hall compressor Model HS 2022, the unit is fitted with a Fridge watch controller, one day the unit micro just wont operate an the LED display just show 0000 (zeros), I dont have any manual of both the unit and the micro controller, the old contractor doing the service may have taken it, can any body help me to figure out what is the problem.
