1.1 

General

 

 

The compressor unit supplies and circulates helium continuously in the cryopump system 

for operation of the refrigerator unit (coldhead).   

The  C15T  compressor unit  consists  of: 1) compressor  motor, 2) cooling system, 3) oil 

separation system and 4) adsorber. 

See Table 1-1 for the standard compressor specifications.
