Petersburg Cooling Tower Auxiliary Power Usage with VFD’s/ Control Strategy Michael J Smith – IPL Engineering & Project Management Abstract--The temperature control strategy for the cooling tower fans involves two automatic modes of operation as well as provisions for manual operation. Both modes will provide sequencing for starting/stopping each of the 14-250hp‚ 480vac fans that have been made available for automatic control. Auxiliary power savings on the 3MVA‚ 4160vac tower load can be

National Cranberry is a cooperative of berry growers around North America that share common production facilities and for the last several years have been experiencing capacity bottlenecks among other issues. After initial analysis‚ two main factors that contributed to a decrease in production were found. The first issue in the business is that the supply trucks and drivers delivering the harvest were not properly organized and there was not enough space and organization to allow for smooth offloading
