1. COMPRESSOR UNIT DESCRIPTION
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.
