Compressor Controller and Demand Expander
The Gardner Denver ESP 20/20
Central System Controller features a main processing unit with a graphical touch-screen Human/Machine Interface that will manage from 2 through 12 air compressors. The base control features the exclusive Bullseye control scheme that uses the Gardner Denver Rate of Pressure Change control algorithm to efficiently add and delete compressors while maximizing the use of control storage (when used in conjunction with the Gardner Denver XMX Demand Expander).
The Gardner Denver XMX Series Demand Expander
The Gardner Denver XMX Series Demand Expander Control provides the benefits of managed compressed air storage and reduced system demand as a result of reduced system pressures. When used in conjunction with an ESP 20/20 Air Compressor Control System, the Demand Expander will provide for maximized air compressor efficiency by creating real storage in the receiver tanks. The system is then maintained at the lowest tolerable pressure level reducing the flow through leaks and unregulated applications. The XMX Series Demand Expander Control will allow reduced plant air pressures, while maintaining air-flow thus enhancing the process through compressed air consistency.
