Last weeks multiple massive thunderstorms caused major power dips, voltage spikes/surges, voltage fluctuations, phase losses and generator switch-overs. All of these electrical eventsĀ  can create havoc upon sensitive electronic devices. VFDs are no exception.

During these storms with all of the electrical activity occurring, 4 separate, critical VFDs running air handling systems throughout the hospital unit failed. Clean, filtered air flow is a necessity in these locations. Delta was called to evaluate these failed units on an emergency basis. The hope was that Delta could quickly repair these VFDs. Unfortunately, all 4 of the units were damaged beyond any economical repair. Delta immediately provided 4 new replacement VFDs and had them all retrofitted into the old VFD panels, up and running, overnight.
