About the SG-12

The SIGNET® Smart SG-12 Cryopump is the largest model in the SIGNET Smart series.  Designed for use in sputtering and evaporation systems, it has high argon capacity and features SHI’s patented double-inverter technology.  This allows up to six (6) cryopumps to be paired with two (2) compressors under normal heat load operation, improving pumping performance stability through control of both the cold head and the compressor motor speeds, while offering increased energy savings with a reduced footprint.
