Kinetics GC 100

System overview

The Kinetics GC 100 Manual Gas Cabinet is a low-cost, easy-to-operate gas dispensing system, designed to provide an exhausted enclosure for the safe dispensing of toxic and hazardous gases used in semiconductor and photovoltaic manufacturing. This simple gas cabinet is intended primarily for simple flammable and non-corrosive gases (e.g., O2 , H2 , CH4 ), and features an automatic gas shut-off valve in the event of a gas leak or emergency shut-off. This gas cabinet is available in single, dual, or three-cylinder configurations. For dual-cylinder configurations (both cylinders containing the same gas), cylinder switch-over occurs automatically, when the pressure of the cylinder drops to a low level. The system has a very simple electronic controller which actuates a simple indicator light when a cylinder is empty, and also shuts down the system under emergency conditions.


The Kinetics GC 100 Manual Gas Cabinet features a simple PLC Controller, designed to:

  • Shut down gas flow under emergency conditions
  • Responds to a gas leak in the exhaust line
  • Indicates when a gas cylinder is empty


  • Second regulator stage for variable pressure outlet (with two gas cylinders)
  • Analog gauge on high-pressure side of regulator, with electrical contact to indicate empty cylinder. Connects to an external Building Automation System (one per cylinder)
  • Analog gauge on high-pressure side, with signal to indicate an empty cylinder. Includes simple controller with “Cylinder Empty” light (one per cylinder)
  • Purge gas connection for cylinder changes (one per cylinder)
  • Cylinder scale for determining an empty cylinder for liquid gases (one per cylinder)
