⭕ CTI-Cryogenics 9600 Helium Compressor - NEW IN CRATE - PN 8135900G001

New In Crate, CTI-Cryogenics 9600 (Helium) Compressor

The operation of CTI-CRYOGENICS cryopumps is based upon a closed loop helium expansion cycle. The system is made up of two major components: the cryopump, which contains the cold head, and the helium Compressor which compresses the helium gas. Refrigeration is produced in the cryopump cold head through periodic expansion of high pressure helium in a regenerative process. The high pressure helium is provided by the Compressor. Low pressure helium returning from the cold head is compressed into the necessary high pressure to be returned to the cold head. The energy required to compress the helium is rejected as heat through the cooling water. High pressure room temperature helium is transferred to the cold head through the supply lines. After expansion, low pressure helium is returned to the Compressor (at or near room temperature) to repeat the cycle in a closed loop fashion. Large separation distances can be accommodated between the Compressor and the cryopump. In the Compressor, helium is compressed using a highly reliable oil lubricated commercial Compressor. Helium purification takes place via several stages of oil removal. The final stage of purification is performed with a replaceable adsorber cartridge. In order to maintain peak efficiency, the adsorber must be replaced every three years. Shipping or can be collected. Returns accepted within 30 days of received unit.
