InteliSys Gas

Description

The InteliSys Gas is a high-end, specialized controller designed specifically for the demanding requirements of gas-powered engines. While diesel engines are relatively straightforward to govern, gas engines (Natural Gas, Biogas, or Landfill Gas) require sophisticated control over the air-fuel ratio and ignition timing.

This controller is the “Industrial Gold Standard” for CHP (Combined Heat and Power) and Cogen applications. It doesn’t just manage the engine; it manages the entire thermal process, ensuring that heat recovery is maximized while the engine runs at peak electrical efficiency.

Key Features of the InteliSys Gas

• Total Gas Engine Management: Built-in support for controlling gas mixers, throttles, and ignition systems via specialized communication protocols or analog outputs.

• CHP & Cogen Optimized: Advanced logic to manage heat exchangers, pumps, and cooling circuits to ensure thermal energy isn’t wasted.

• Built-in PLC: Features a high-capacity PLC interpreter with a library of gas-specific functions, allowing for site-specific customization without external hardware.

• Detachable Display (BaseBox): Like other “Sys” models, it is a display-less unit mounted inside the cabinet for protection, paired with a remote InteliVision color screen.

• Communication Powerhouse: Native Ethernet and support for various industrial protocols (Modbus TCP, SNMP) to integrate into large-scale plant SCADA systems.

Critical Technical Notes: 

External Hardware Required: The InteliSys Gas often requires external modules like the ECON-4 (for electronic speed governing) or various InteliIO modules to manage the high number of sensors found in a gas power plant.

• Fuel Flexibility: This controller is capable of managing lean-burn engines and can be configured to handle fluctuating gas quality (common in landfill and biogas sites).

• Mixing it Up: It is frequently used with the InteliVision 8 or InteliVision 12Touch displays to provide operators with a detailed visual map of the CHP thermal process.

• Legacy Status: While the InteliGen 1000 is the new “all-rounder” flagship, the InteliSys Gas remains the preferred choice for dedicated gas technicians because of its deep, pre-built library of gas-specific PID loops.
