IGV
Inlet Guide Vane vs. Butterfly ValveAn IGV offers about 3.5% to 4% BHP better power reduction than a butterfly valve, but only at maximum "safe" turndown (throttle). Lower temperatures offer better, improved savings.
Payback:We found the current payback period for one IGV to be close to eleven years. In some situations, where several IGV are purchased and installed, the payback period was calculated to be as much as 43 years or more.
