Used EDWARDS E2M175 #9205959 for sale

EDWARDS E2M175 is a cryopump designed for high-vacuum applications, and is an excellent choice for industrial and research applications that require clean, reliable and precise vacuum conditions. This cryogenic pump is designed with an oil-free rotor design which allows it to be used in a variety of industrial and laboratory environments. E2M175 pump works on the principle of cryogenic pumping, which involves cooling a gas to a low enough temperature that the remaining molecules have sufficiently low kinetic energy to adsorb onto the surfaces of a cold trap. The cryopump features a large chilled aluminum plate, also known as the cryopanel, which is cooled by liquid nitrogen to cool the rotor to cryogenic temperatures, approximately -260°C. This allows the pump to draw molecules from the chamber to the panel as if drawn by a magnet. The design also incorporates a pressure-limiting valve built into the cryopanel, which helps to maintain system vacuum levels. The pump is relatively compact, and has a nominal pumping speed (NPS) of 67 m3/h. It can reach low ultimate pressures of 3 x 10-8 mbar. EDWARDS E2M175 has a self-contained circulation loop to ensure continuous cooling of the cryopanel and maintain the desired pumping performance. In addition to its cryogenic pumping capabilities, E2M175 is also equipped with a venturi foreline pump, as well as foreline and roughing filters to maintain the cleanliness of the chamber and get rid of any potentially disruptive gases. An additional feature is the inclusion of an optional ion-pump to help reduce the level of contaminants that make it through the pump, such as hydrocarbons. EDWARDS E2M175 is easy to install and maintain, with very low operation costs. Being a relatively advanced cryogenic pump, it is also a very energy-efficient machine, capable of running on a fraction of the power of a traditional vacuum pump. E2M175 is an ideal choice for any laboratory or industrial application that requires clean, consistent and reliable results.
