Variable inlet guide vane (IGV) is used to control the mass flow and generate prewhirl in centrifugal compressors. IGVs are a series of blades circumferentially arranged at the inlet of compressor, driven electronically or pneumatically. Two devices are used to control the inlet flow to a centrifugal air compressor: inlet butterfly valve (IBV) and inlet guide vanes (IGV). The following interview describes how centrifugal compressor efficiency can be improved thanks to recent developments in IGV technology. Fast and accurate positioning of Inlet Guide Vane (IGV) is critical for flow regulation in centrifugal air compressors, especially for surge avoidance control.
