SPIRAL VALVE TechnologyVariable Displacement Air EndThe Sullair variable displacement air end maintains constant systempressure to the plant. Since Spiral Valve compressors use large, efficient,slow running rotors, a lower power consumption is achieved at the topend of capacity. Oil foaming does not occur, air is not wasted to theatmosphere, and bearings last longer.Increases Capacity Control EfficiencyBy activating automatically when the unit is operating under partialload, the modulating valve goes down to as low as 40%, and allowingcompression of only the required quantity of air, the spiral valve increasesthe efficiency of the compression process. The ultimate result is greatercompression efficiency and reduced power consumption infinitely variablefrom 50–100% capacity.Sullair’s Variable Capacity Control TechnologyThemotorair endrun atOperationoptimum speed and, therefore,maintainHowtheandSpiralValveload control system to 50% output.the plantto match air demand. putrange.HowtheSpiralValveOperationWorksis extremely simple andWorksThis systemthe VCC compressors use large,Therotors,compressionvolume variesto suit athecostair demandby progressivelyprovideseffective,energyefficient, slow runninga lowerThe compression volume varies to suitSullair Spiral Valve compressors react instantly to ntheairend.efficient control alternative.power consumption is achieved at thethe air demand by progressivelydemand.
