NGSG SMART System Highlights:

  • Reduce shutdowns by as much as 25% over industry standard compressors*
    • 100% turn down of flow - 24/7/365
    • Elimination of pressure, horsepower, and rod load related shutdowns
    • Rock-solid pressure control over the widest range of process needs & upsets
    • Robust freeze avoidance for uninterrupted operation in cold weather
    • Run through fluctuating BTU fuel gas upsets rather than shutting down
  • Maximum power and flow optimized over the entire range of process conditions – done automatically
  • When N+1 units are installed, compressor flow reliability approaches 100% as the multiple machines automatically increase flow to fill gap when unit goes down
  • Dewpoint control – Temperature process control to within 2-4°F of setpoint
  • Telemetry via cellular or satellite of package data (includes ALL engine panel information too):
    • Remote setpoint allowable
    • Monthly sorting and tally of alarms/shutdowns for continuous improvement
    • Both, customer connection at panel & web-based access to real time and historical data
