AirLogix® is an advanced control solution for centrifugal air compressors. Built on the Allen-Bradley family of PLCs and coupled with our modern control technology we’ve developed a solution that delivers unmatched results. AirLogix® optimizes energy efficiency, increases reliability, and promotes system visibility through data and integration. Each controller we build is custom, engineered specifically for each application with nearly unlimited capabilities.

What sets AirLogix® apart from any other controller on the market is our unique control algorithms and methodology. Through decades of experience, we’ve developed a product that completely automates and optimizes the compressor. To achieve this, we continuously monitor and adjust for real-time major factors on performance such as changes in ambient air temperature, pressure, and various rate-of-change functions.

AirLogix® is incredibly user-friendly but also open-source which means it consists of no Case Controls proprietary hardware. Our thoughtfully designed HMI home screen provides an easy to understand and detailed machine information at a glance. Additional secure screens provide the ability to create and tailor personalized views to display the information that is of the greatest interest to you. We provide all of the tools needed to add, name, scale, configure I/O, tune PID loops, take manual control of the valves, and much more.

Unlock the true potential of any centrifugal air compressor with AirLogix®.

Dynamic Throttle Limit (DTL™)

Case Controls unique proprietary control algorithm which compensates for changes in ambient air temperature fluctuations. This provides for greater turn-down in centrifugal compressors resulting in improved energy savings and superior surge control protection.

Full Control HMI Functionality

Human machine interface (HMI) allows for the complete configuration, tuning, troubleshooting, and operation of the compressor. Complete with detailed information, data trending, and graphics for easy to use and understand control at the fingertips.

Industry Standard Automation - Allen-Bradley PLCs and HMIs

Built on the Allen-Bradley line of factory automation by Rockwell, Case Controls uses ZERO proprietary parts. This means customers are free to select from a worldwide distribution network and multiple vendors for Rockwell Automation Allen-Bradley hardware.

Documentation & Diagrams

Complete new documentation sets including wiring diagrams, user-manuals, part’s lists which thoroughly address set-up, tuning, troubleshooting and operations.

Software Back-Up Copies

Back-up copies of the specific buildout are provided on flash drives or memory disks and shipped installed in the PLC and HMI for insurance in case of hardware failures.

Ethernet/IP Communication

Standard communication protocol method is Ethernet/IP. Other protocols are optional for connection to any third-party system.

Plug and Play Retrokit

Tried and true control upgrades for OEM legacy controllers which make for fast and easy installation. By utilizing the existing enclosure, Retrokits are designed to fit with minimal additional work.

AirLogix® compatible with 3PX-Backbone™

This feature enables and permits the electronic integration of Case Controllers with numerous third-party controllers. A piggyback solution that negates the requirement of replacing all the controllers of a system.

Plug and Play Retrokits

AirLogix® can be configured for a quick plug and play installation. Typical installation can be completed in approximately four hours for compressors with the following OEM control systems:

• Ingersoll-Rand MP3, CMC, Xe
• Joy, Cooper, Cameron Quad III, Quad 2K

Retrokits include additional instruments and transmitters to complete installation. In some instances, the PLC requires a satellite enclosure due to space limitations in the existing enclosure.
