Overview
Azbil is headquartered in Chiyoda, Tokyo and was formerly known as Yamatake. It works in building automation, advanced automation for factories and life automation.
In semiconductor fabs it provides air conditioning control for cleanrooms, and inside equipment it supplies pressure and flow sensors, proximity and photoelectric sensors, control valves and controllers.
Business: Sensors, control valves and cleanroom air conditioning control
Why it matters
- Cleanroom pressure, temperature and humidity must be held steady around the clock, which is a control problem as much as an equipment one.
- Azbil works on both the building side and the equipment side of a fab.
