This paper introduces two stepless capacity control systems for reciprocating compressors: Dresser-Rand’s Infinite Step Control (ISC) system and Hydraulic Variable Volume Clearance Pocket (HVVCP). Case studies describe the relative advantages of each unloader system and how they increase compressor efficiency and reduce energy costs.
