Varian, Inc. Debuts More Efficient, Longer Life Navigator Turbo-V 301 Turbomolecular Pump; Newest Addition to Navigator Line Increases Uptime in Vacuum Applications.Business Editors/High-Tech Writers SAN FRANCISCO--(BUSINESS WIRE)--July 16, 2001 Varian, Inc. (Nasdaq:VARI Va´ri n. 1. (Zool.) The ringtailed lemur (Lemur catta) of Madagascar. Its long tail is annulated with black and white. ) today unveiled a major evolution in its groundbreaking "plug and pump" Navigator(TM) turbomolecular pumps A turbomolecular pump is a type of vacuum pump, superficially similar to a turbopump, used to obtain and maintain high vacuum. These pumps work on the principle that gas molecules can be given momentum in a desired direction by repeated collision with a moving solid surface. that reduces power consumption and bearing temperature significantly, resulting in extended pump life. The Navigator(TM) Turbo-V(TM) 301 delivers 300 liter/second performance using half the power of previous models and can be easily integrated into a range of systems requiring superior vacuum performance. In semiconductor and thinfilm applications, such as load locks for ion implanters, the extended pump life of the Turbo-V 301 reduces costly downtime for semiconductor manufacturers. The Turbo-V 301 can also be integrated into liquid chromatography/mass spectroscopy instruments used in life science applications and gas chromatograph/mass spectrometry spectrometry /spec·trom·e·try/ (spek-trom´e-tre) determination of the wavelengths or frequencies of the lines in a spectrum. spec·trom·e·try n. for environmental analysis. The Turbo-V 301, engineered for high efficiency, reliability and extended pump life, sets new performance standards through an extensive redesign of the already state-of-the-art MacroTorr(R) pumping section. Redesigned pump stages featuring optimized geometry enable foreline pressure operations up to 12 Torr, full pumping speed up to 10(-3) Torr (mbar), and pump operation at atmospheric pressure atmospheric pressure or barometric pressure Force per unit area exerted by the air above the surface of the Earth. Standard sea-level pressure, by definition, equals 1 atmosphere (atm), or 29.92 in. (760 mm) of mercury, 14.70 lbs per square in., or 101. . Heat dissipation Noun 1. heat dissipation - dissipation of heat chilling, cooling, temperature reduction - the process of becoming cooler; a falling temperature and performance is assisted through improved cooling fins and an innovative heat sink A material that absorbs heat. Typically made of aluminum, heat sinks are widely used in amplifiers and other electronic devices that build up heat. Small heat sinks are the most economical method for cooling microprocessors and other chips. body, which reduces bearing temperature and wear. Ceramic bearings also make the Turbo-V 301 virtually maintenance free. The new pump is compact -- occupying a fraction of the space of Varian TV250 and TV300 HT pumps -- simplifying integration into OEM (Original Equipment Manufacturer) The rebranding of equipment and selling it. The term initially referred to the company that made the products (the "original" manufacturer), but eventually became widely used to refer to the organization that buys the products and systems. The Turbo-V 301 is designed for quick "snap" attachment of the pump to the control unit in almost any configuration including vertical, horizontal, and upside-down orientations. Flexibility and reliability are further extended through optional integration with DeviceNet, a widely used open communications network The transmission channels interconnecting all client and server stations as well as all supporting hardware and software. and protocol platform designed to connect industrial devices to control systems. The "plug and pump" design behind the Turbo-V 301 extends to the interface of the control unit, which can be mated to a laptop running the Navigator software package and connected simply via a serial cable. The unit is also ready for operation with Varian's MoniTorr diagnostic device -- which allows the anticipation of turbopump failure, and maximizes uptime in industries where downtime can be extremely expensive. It can also be connected to Varian's Remote Assist maintenance program. The Turbo-V 301 will be available for shipment in October 2001. For additional information or literature, contact: Varian, Inc.
