Semi Fab Upgrades Gas Cabinet with Echoline to Prevent Costly Shutdowns

Semi Fab

Gas Cabinet and BCDS


Risk of Harm

  • Semiconductor Fab needs to detect any drift or exhaust failure
  • Semi S6 Tracer gas testing: concentration >OEL/LEL
  • Human and environment hazards protection
  • Operators need to know that the tool is safe
  • UL991/S2-0818 Safety interlocks
  • Fail to safety
