Tim,

I work in industrial automation field and I know how a little bit of equipment can save electronics againts power surge and storms.
Can you please tell me what is the power supply of this equipment? By that, I mean the voltage and the current or wattage.
A storm can break the control part of the electronic, but not the motors, which is what is important in a chiller.
There is probably a simple thing to do to put it back in working state, if you can provide a picture or two (or 3) of the control part of the equipment.
