GREATER THAN 45% ENERGY SAVINGS IN A COMPACT BLOWER DESIGN

Inovair Reduces Power Consumption By More Than 45% At Water Resource Recovery Facility

The Kill Creek Water Resource Recovery Facility was looking for a way to reduce power consumption at their plant, and investigated replacing their existing 125 HP multistage blowers with a more efficient option. The Inovair IM-20 was the perfect solution, as the top discharge and small footprint allowed the Inovair IM-20 to be installed on the same pads as the existing multi-stage blowers and required minimal piping modifications. The direct drive high-efficiency IM-20 only needed 75 HP to meet the design flow 1350 SCFM @ 7.5 PSIG, allowing the existing electrical to be reused. This increased blower efficiency reduced energy consumption by 40%. Improved process control from Inovair’s in-house designed control system delivered further improvement, for a total energy savings of 47%. According to Scott Millholland, Kill Creek WRFF Superintendent “With over 45% energy savings compared to our previous multi-stage blowers, this project pays for itself very quickly”. A further benefit of the high efficiency of the Inovair IM-20 blower was a reduction in the blower room temperature by at least 15 Degree F.
