The new 2-in-1 HSD compressor features two independently operating compressors in a single enclosure. The units are available from 500 to 650 hp, and deliver 1,632 to 3,002-cfm flows, and 100 to 217-psig pressures. Each complete compressor unit includes a motor, Sigma Profile airend, separator aftercooler, drain trap, and filtration.
The compressors are started one after another to reduce inrush current and protect against network overload. Both compressor units have dedicated Sigma Controls connected via Profibus for energy-efficient sequencing and fully automatic monitoring of critical operating and maintenance indicators.
