Cryo-Torr Cryo Pumps
Description:
CTI Cryo Pumps are the industry standard for a wide range of cryopumping applications. The Cryo-Torr series was the original cryo pump produced by Helix, later acquired by CTI and now Brooks Automation. Cryo-Torr models provide robust cryo pumping capability, but offer limited performance and health indication.

Enhanced CTI Cryo Pumps
CTI manufactures several variants of standard cryo pumps as enhanced versions. These enhancements are accomplished through modifictions to the 15K and/or the 80K arrays. The resulting benefit of an enhanced cryo pump is that it will typically be “tuned up” for a specific application. As an example, Enhanced 8F cryo pumps have increased capacity for Argon, which is useful in sputtering, while Enhanced 250F cryo pumps have increased Hydrogen pumping speed, which is beneficial in Ion Implantation. Contact Trillium for more details on purchasing an enhanced cryo pump or upgrading your current pump fleet.
Selecting a Cryo Pump
When choosing a cryo pump, select a model that produces the appropriate pumping speed for the gases used in your process. Secondly, ensure your system can physically accomodate the size of pump you need. As a rule of thumb the model indicates the diameter of the cryo pump vessel (e.g. CT8 = 8 inches, CT250F = 250mm). Thirdly, ensure the cryo compressor you have or are considering is sufficiently sized to handle the number and size of cryo pumps.
