Case Controls Products
AirLogix is a control solution for centrifugal compressors built on Allen-Bradley CompactLogix and ControlLogix PLCs using PanelViewPlus HMIs. This system is completely supportable with your own resources. The control scheme automates the compressor entirely and continuously adjusts to real-world conditions.
AirLogix Features & Benefits
- Air Density Compensation resulting in a Dynamic Throttle Limit (DTL) to protect against surge while operating to minimize blow off.
- Well-conceived screens provide the operator with detailed machine performance information.
- AirLogix can be configured for plug and play installation with major OEM control systems.
OEM Retrokits Available
- IR – MP3, CMC, and Xe
- Cameron – QuadIII, Quad2000 (Skid Mount and Console)
AirStarPD™ is the trusted aftermarket local controller to manage one Rotary Screw or Reciprocating compressor. AirStarPD can be applied to both fixed speed and VFD machines.
AirStarPD™ Features & Benefits
- Built on a Allen Bradley MicroLogix 1100 PLC platform to NEMA and NEC standards.
- Housed in a NEMA 4/12 or 4X enclosure (OEM Retrokits are also available).
- Familiar PLC technology and there are no Case Controls proprietary components.
- Well-conceived screens provide the operator with detailed machine performance information.

Increased Accuracy & Reliability, Decreased Maintenance
- Increased accuracy following demand changes. PID loop-controlled, allowing tuning to plant specific demand.
- Increased efficiency by fully utilizing the spiral valve, thereby minimizing use of the inlet valve throttle.
- Further improved efficiency with coordination of multiple compressors via Case’s AirMaster™.
- Reduced maintenance by eliminating pneumatic solenoids, shuttle valves, regulators and filters.
- Allen Bradley PLC improves reliability, flexibility and supportability.
- Tighter pressure tolerance.
- Quick response to demand changes.
- Improved energy efficiency by turning down capacity.
- Eliminates the need for regular adjustments.
