IRCOCentrifugal Compressor Controllers MAESTRO™ Universal

With a robust feature set and easy-to-use 

interface, the advanced MAESTRO™ Universal 

controller will optimize operation for both new 

and existing compressed air systems.

Optimize Compressor Performance 

and Lower Your Costs

MAESTRO Universal is a state-of-the-art air control system for managing 

centrifugal compressor performance, and the standard controls solution for 

new MSG® TURBO-AIR® and MSG® centrifugal compressors manufactured 

by Ingersoll Rand. Our engineering team can design a customized MAESTRO 

Universal controller upgrade for existing compressed air systems. Unique 

instrumentation packages and monitoring functions are configured to optimize 

compressor performance for each installation and, in many cases, existing 

equipment can be reused to achieve further savings.

Multiple Compressor Management (MCM)

By connecting and controlling several control panels as a team, MAESTRO Universal can load/unload and start/stop compressors 

as needed to modulate compressors, maximizing the efficiency of the entire compressed air system.
