Used CTI-CRYOGENICS Cryo-Torr 250F #293634899 for sale

CTI-CRYOGENICS Cryo-Torr 250F is a high-efficiency turbomolecular vacuum pump specifically developed for use in cryogenic applications. It can provide a maximum foreline pressure of 10-3 Torr or lower with a pumping speed up to 225 liters/second. CTI-CRYOGENICS CRYOTORR 250F utilizes a combined high- and low-pressure mechanism, consisting of a three-stage, high-speed, single-stage turbine drive and cylindrical rotor design. The high-pressure stage is powered by an axial-flow turbine to increase the inlet speed of incoming gas molecules, while the low-pressure stage utilizes an elliptical-flow technique to facilitate the evacuation process. The turbine is driven by an external DC motor, which can achieve rotational speeds of up to 90,000 rpm. The cryogenic environment is cooled by a cryopumping chamber and rotors and stators are cooled to cryogenic temperatures in order to reduce energy losses due to heat transfer. The cryopumping chamber also features a differential pressure and/or temperature monitoring system for continuous operation. Cryo-Torr 250F is designed to be maintenance-free, allowing for trouble-free operation in cases of repetitive and extended use. The device also boasts a low noise level of less than 45 dB(A). It is also protected against thermal overloads and motor stall currents. Overall, CRYOTORR 250F is an ideal choice for high-precision research and industrial applications. Its precise and reliable vacuum generation capabilities make it an invaluable asset in a wide array of cryogenic situations ranging from laboratory experimentation to industrial processes. CTI-CRYOGENICS Cryo-Torr 250F is the perfect tool for anyone looking for a reliable, maintenance-free, and safe pump for cryogenic applications.
