System cooling is accomplished through a primary, oil-to-water based exchange system as well as a
supplemental forced-air cooling system. The main isolation transformer and output filter inductors
are immersed in an oil which then circulates through cooling plates where input rectifiers and output
transistors (IGBTs) are mounted. The oil further circulates through a liquid-to-liquid heat exchanger
where the oil transfers its heat energy into the customer-supplied coolant water also circulating
through the heat exchanger. These heat exchangers intended for fresh chilled water a water/coolant
mix.
