A Proven, PLC Controller for Compressed Air Dryers

AirStarDC™ Air Compressor Dryer Controller

AirStarDC™ is a proven, robust control solution for air compressor dryers built on Allen-Bradley PLCs. This system is completely supportable with your own resources. This familiar PLC technology has no Case Controls proprietary components.

Air Logix PanelAirStarDC™ completely automates the dryer, cycling based on demand for energy management. Well conceived, straight forward screens provide the operator with detailed machine performance information. The screens provide the tools needed to troubleshoot, along with adding additional I/O components to the system.

This control platform has been developed to fit all dryer types regardless of make and model. By providing a common interface for all operators and users the complete system data set is available for remote access for existing connected controllers. AirStarDC™ is the perfect choice for integrating what is a critical component of clean dry compressed air into an automated and visible control system.
