What We Do

Logix Screw Compressor Control System (CCS)


The Logix CCS is an industrial-grade controller featuring real-time status screen, a color touch screen menu, control-alarm-failure setpoints, ramp start/unload setpoints, and so much more.

The CCS controls all major manufacturer's compressors, optionally supports VFD motors and modulated liquid injection valves, and integrates into any control system using Open Communications Protocol.

plot any sensor data, including slide valve % and motor amps
Control, Alarm and Failure Setpoints all setpoints user-defined (with factory-set limits)
Multiple Setpoint Control up to four with daily and weekly setpoint scheduler
Ramp Limited Starting and Unloading allows gradual start-up and prevents overloading
Operating Modes manual, automatic (local and remote), and auto sequence
Operating Logs logs all compressor data for the prior 48 hours of operation
Alarm and Failure Logs displays the prior 100 events with date, time and description
Password Restricted Access assigns up to eight authority levels and logs user access
Adjust Control allows adjusting speed of slide valve movement
Calibrate Sensors provides simple sensor calibration method
