Used CTI-CRYOGENICS Cryo-Torr 250F #293628969 for sale

CTI-CRYOGENICS Cryo-Torr 250F is a mechanically refrigerated cryopump that is capable of producing vacuum down to an ultimate pressure of 10-7 Torr. It operates by cooling a stationary titanium structure with liquid nitrogen to form a cold head. Gas molecules are adsorbed on this cold head. The pump then uses a rotary backing pump to create a coarse vacuum, after which the motorized rotor of the cryopump will complete evacuation of the system. The Cryo-Torr has a 250 liter/second free air capacity which increases with its reduced temperature. It has a high gas throughput rate which allows fast evacuation of large chambers. Its design allows it to quickly recover after losses of refrigeration or power. The pump has a low ultimate pressure and requires minimal maintenance. The pump contains an integrated scroll expander to directly control the speed of the drive motor. Its digital speed control allows for easy optimization by the user. The integrated drive has overload protection for safety, and the electronic components are protected from vibration damage by a built-in shock absorber. The low-noise fan ensures a low sound level in operation, and a low-power consumption makes it energy efficient. CTI-CRYOGENICS CRYOTORR 250F is designed for long service life and trouble-free operation. It has a closed loop cooling system which keeps the cold head temperature stable even during rapid loads of gas. It is compatible with the major vacuum measurement standards and can easily be connected to a proprietary controller. The mounting flanges are compatible with standard flanges. Cryo-Torr 250F is a reliable and versatile cryopump that offers an ideal solution for sustained vacuum production with fast evacuation times. It is durable, low-maintenance, and can be easily integrated into a variety of systems. Its excellent performance and reliability make it an ideal choice for high-vacuum applications.
