Basic Compressor Throughput (Process, Performance) Control

The most basic compressor throughput control is typically accomplished with: discharge throttling, suction throttling, guide vane positioning, or speed control.

Basic Compressor Throughput (Process, Performance) Control


Typical Tri-Sen Basic Compressor Throughput Control includes:

  • Automated start-up / shutdown sequencing
  • Adaptive PID tuning
  • Bumpless transfer between process PID controls
  • Bumpless process PID Auto/Manual transitions
  • Process limit override controller(s)
  • Auxiliary controls (seal gas, lube oil, etc.)
