中重負荷向けドライ真空ポンプの省エネルギー化

抄録

  For dry vacuum pumps, typically used for chemical vapor deposition (CVD) and Etching process in semiconductor factory, the durability of byproduct deposition and /or corrosion is very important. And also energy saving is one of the key factor on this application for cost ownership stand point.
  Our ``Model EV-M'' dry pumps have achieved significant enhancement for saving energy consumption, and have incorporated various countermeasures against byproduct deposition and corrosion, like optimized internal temperature profile and material selection. With these, both significant saving energy and process durability can be achieved under the use of the harsh duty condition such as CVD and Etching process.
