In 1970, the first of five toroidal chamber rotary
compressors entered service in nuclear test loops. Each of
these machines was used to circulate 2,240 scfm of
CO2 at 660°F; the suction and discharge conditions
were 870 and 942 psia, respectively. Since then, many of
these single- or multi-stage rotaries have seen service on
gases ranging in molecular weight from 2 to 44, flows from an
extremely low 15 scfm to as high as 39,000 scfm, and power
inputs from 15 to over 600 hp.
In essence, these rotary compressors offer the same
performance as traditional low-flow compressors, but do so at
considerably lower speeds: 500 - 6,000 r
