AirSequal™ is an Allen Bradley PLC based control system designed to automate 2-6 air compressors of various sizes, makes, and models. AirSequal™ is a supervisory level control system and interfaces to the OEM local control system through hardwired discrete inputs and outputs. The OEM control system protects the individual compressors as it does today. The PLC brings obvious advantages of flexibility, availability and serviceability by a number of resources. The copyrighted software or “source code” (part of which is known as ladder logic) is the property of iZ/Case. It is licensed to users for installation and use on a single compressed air system.
Add an optional flow meter to unlock FlowSeq. As demand changes, the AirSequal will automatically adjust to run the appropriate compressor lineup for maximum efficiency.
Base/Trim Control- The system can coordinate multiple variable capacity control systems in order to prevent multiple part-loaded matches from running at the same time. The system automatically matches the correct HP to current plant demands.
Full calendar-based system control. Run the system how and when you want to. The AirSequal can automatically select a sequence based on the time of day and day of the week to best match production demand.
Auto rotation functionality is available with the intent of maintaining equal runtime across the compressors. Two auto rotation functions are available: Compressor Runtime Based Rotation and Preset Sequence Based Rotation.
Remote viewing of the AirSequal plus 90-day trend history allow you visualize the impact of our system. Alerts and notifications via text or email provide up-to-date information to keep your system safe. All of these features are accessible via your computer or mobile device.
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.
Whether on-site, by phone, or via modem connection, support is prompt, effective, and available 24/7.
Complete new documentation sets including wiring diagrams, part’s lists, and user-manuals which thoroughly address set-up, tuning, troubleshooting and operations.
Native Ethernet/IP and Modbus communication protocol. Other protocols are optional for connecting to any third-party system.
