ACITY CONTROL OPTIONSSpiral Valve TechnologyHow the Spiral Valve Operation WorksThe compression volume varies to suit the air demandby progressively opening or closing internal bypassports on the air end.CO MPR ESSO R PER FO R MA N CE CO MPARISON100PO WER ( %)80Capacity is matched to system demand, reducingcycling time and extending component life.6040Part-load capacity and efficiency can produce energysavings from 17–35%.LOAD/UNLOAD*INLET MODULATION W/BLOWDOWNSULLAIR SPIRAL VALVE200102030405060708090100FLO W ( %)Variable Displacement Air EndThe Sullair variable displacement air end maintains system pressureto the plant to match air demand. Since the Spiral Valve compressorsuse large, efficient, slow running rotors, a lower power consumptionis achieved at the top end of capacity. Oil foaming does not occur, airis not wasted to atmosphere, and bearings last longer.The chart above is a representation of nominal control systems for generic comparativepurposes. A detailed and accurate comparison of specific compressor models is availablefrom your authorized distributor.The motor and air end run at optimum speed and therefore maintainoptimum efficiency throughout the full variable output range.Sullair Spiral Valve compressors react quickly to rapid changesin demand. The effective rotor length is progressively reduced asthe demand is reduced which provides the most efficient part loadcontrol system to 55% output. This system is extremely simple andprovides a cost effective, energy efficient control alternative.BYPASS PORTS IN STATORRotors removed to show Bypass PortsCLOSED BYPASS PORTSPARTIALLY OPEN BYPASS PORTSOPEN BYPASS PORTSAIR INLETAIR INLETAIR INLETCOMPRESSEDAIR OUTEFFECTIVECOMPRESSIONVOLUMECOMPRESSEDAIR OUTEFFECTIVECOMPRESSIONVOLUMECOMPRESSEDAIR OUTEFFECTIVECOMPRESSIONVOLUME9
