The Bulk Specialty Gas System (BSGS) is a state-of-the-art distribution system designed for safe, automatic delivery of bulk specialty gases. The PLC-based controller provides the operator with intuitive, easy-to-use touchscreen and on-screen prompts to simplify operator interaction with the machine. The graphical interface allows an operator to quickly determine the status of the tool with a glance at the screen. The panel buttons and on-screen menus offer easy access to any of the controller screens. 

The BSGS is designed to distribute gas to a distribution line from one or two bulk supplies, such as various configuration of cylinder bundles, y-size cylinders or tube trailers. The system can be configured for high-flow or ultra-high-flow applications with dual stage pressure regulators, block heaters and source heater controls. Exentec designs its systems to ensure the best uptime in the industry with the most stable supply record. The system software is designed to improve efficiency and extend the lifetime of the tool.
