Inovair operating 24x7 trouble-free in high-pressure waste treatment application
A waste treatment plant in Arkansas was having issues with their screw PD blower reliably operating on their equalization tank. The blower had failed several times forcing the plant to operate with a spare blower. When the spare blower also started having issues, the plant reached out to Inovair to see if they could provide a more reliable option. The new blower would have to provide 1,750 ICFM @ 15.6 PSIG and also be able to operate at 19.0 PSIG with reduced flow. Because of the plant’s limited budget, they would need to be able to install the new blower themselves, re-use any electronics as well as any piping and appurtences. Also, as the spare blower was limping by, the plant would need delivery and installation of the new blower within six weeks. Because the Inovair geared centrifugal blower was designed for applications just like this, with its ability to operate up to 22.0 psig, Inovair knew their proven reliable geared centrifugal blower would operate trouble-free in this application.
Since the failed screw PD blower was only a couple years old, the plant asked if Inovair would be able to use the existing 150 HP VFD. The problems associated with the failures of the screw blower were due to the blower itself and the VFD was in good operational shape, so Inovair was able to re-use the existing VFD. Having the ability to re-use VFDs is a standard feature of the Inovair blower line and allows a plant to not only reduce capital costs but to reduce installation costs as well.
With the VFD already in place, all the plant had to do was remove the non-functioning screw blower and install the new Inovair IM-30 geared centrifugal blower. The Inovair IM-30 is shipped pre-wired and the low vibration characteristics of the blower mean that no special pads or mounting structure was necessary. The Inovair IM-30 was shipped within four weeks of the purchase order, a full two weeks before the deadline. After a short 4-hour trip from Inovair’s manufacturing and testing campus, the new blower was installed in a few hours by plant personnel. Inovair field service technicians finalized the start-up process on the same day and the blower started as expected. The Inovair IM-30 has been operating trouble-free in this high-pressure application 24/7 ever since.
