Restaging/rerating of centrifugal compressors: Fundamentals, practices and challenges Restaging/rerating of centrifugal compressors: Fundamentals, practices and challenges The primary requirement for rerating or revamping an existing centrifugal compressor is to match the new operating requirements, such as increased or decreased flow, increased or decreased head, or a combination of both. Rerating or revamping is necessary where the existing compressor or compressor train is incapable of meeting the new operating requirement efficiently. The primary requirement for rerating or revamping an e...
