SEMI-GAS Systems, a provider of ultra-high purity gas delivery equipment, recently expanded the capabilities of its GigaGuard GSM controller to include PLC operation of six, seven and eight stick gas distribution systems. This controller provides fully automatic purging capability and gas management from a single source to multiple points of use, as needed in semiconductor and LED manufacturing applications.
Used in conjunction with the SEMI-GAS Nanoturion Valve Manifold Box, the GigaGuard GSM Controller is designed for the safe and continuous distribution of hazardous process gases. It supersedes the previous model with modern PLC technology and enhances the GigaGuard GSM line of semi-automatic and fully-automatic distribution controllers.
The adaptable new controller offers adjustable alarm set points and user-configurable inputs and outputs to maximize customization for each application. In addition, the GSM controller features a modern 4.3-inch color touch screen with easy-to-use software prompts and alarms, helping reduce operator error and increase safety.
The GigaGuard independently operates ESO valves, monitors analog and digital process sensors, displays delivery pressures, maintains alarm logs, and continuously monitors system operations for hazardous conditions. For added safety, both local and remote system shutdown capabilities are incorporated in the event of an alarm trip.
All GigaGuard controllers meet SEMI S2, SEMI S8 and uniform fire code requirements as required for the safe handling of hazardous process gases. The controller enclosure is constructed of 16 gauge steel and includes a SEMI-approved EMO (emergency off) button and multi-color LED panel status lights. A flip-down door provides easy access to controller components, including the Siemens S7-1200 series PLC.
“The new GigaGuard controller offers a dramatic upgrade in performance, versatility and value compared to the previous version,” said Jim Murphy, SEMI-GAS Systems’ division manager. “The GigaGuard product line sets the standard in gas handling controls by offering complete operational customization for each application.”
