A wastewater treatment plant in Western Kentucky was looking for a new blower system to replace their existing 150 HP multi-stage blowers. The plan was to replace 2 of the multi-stage blowers and keep the 3rd as a stand by unit. Even though the plant recently added variable frequency drives (VFD’s) on these blowers the performance was not what they expected and the decision was made to upgrade. An evaluation would be made on different high efficiency blowers comparing capital cost, power consumption, and ease of installation. Additionally since the existing VFD’s were relatively new it would be advantageous to be able to re-use the existing VFD’s. After a thorough evaluation the Joint Sewer Authority (JSA) selected the IM-30 Geared Centrifugal Blower in a stacked configuration.
The Inovair IM-30’s competitive capital cost, high efficiency, and easy installation provided JSA with the lowest cost of ownership. Inovairs design philosophy of VFD placement to be installed local or remote allowed the authority to keep their exiting drives and simplified installation and reduced capital costs even further. Inovairs proven stack configuration provided the JSA a seamless and efficient flow range (1150 -5250 SCFM) in a single footprint. This nearly 80% turndown coupled with Inovairs designed and built control system ensures smooth and efficient operation during all flow conditions.
