Edwards advanced semiconductor vacuum pumps have been field-proven to perform to the highest operating standards. Reliability and high performance are achieved by extending service life, improving uptime and increasing productivity, while minimizing footprint and cost of ownership.
The iH Series offers high reliability for difficult processes, such as PECVD and LPCVD, where particulate, condensable and corrosive by-products are present.
The iH system operates at pressures between atmospheric and ultimate vacuum with no lubricating or sealing fluid in the pumping chamber. This ensures a clean pumping system without back-migration of oil into the system being evacuated.
The iH1800 system has an HCDP160 dry pump with an HMB1800 mechanical booster pump fitted to the inlet of the HCDP160 pump. Both the HCDP and HMB pumps have enclosed, water-cooled motors. The iH system is therefore suitable for applications in clean environments where fan cooling of motors is unacceptable.
The iH system has a gas system which introduces purge gas into the HCDP pump. This gas system is suitable for use on harsh duty processes. If you use the iH system on light or medium duty processes, you can use the economiser gas mode to reduce the consumption of purge nitrogen by the pumping system.
You can manually control the iH system through the Pump Display Terminal. Alternatively, you can use your process tool or other control equipment to control the operation of the iH system through an Interface Module accessory, or through an iH Communications Module accessory, or you can use the iH Single Pumpset Monitor accessory to control the operation of the iH system.
