Tandem rotary screw compressors

The company has redesigned its 100- to 600-horsepower two-stage tandem rotary screw compressors for increased energy efficiency and operating performance. To save energy, the compressors match pressure and capacity with system demand. The capacities of constant-speed drive models (TS-20, TS-32 and TS-32S) range from 500 to 3,000 actual cubic feet per minute (acfm). Variable-speed drive models (V-200TS and V-320TS), which offer additional full- as well as partial-load energy savings, have capacities ranging from 495 to 2,310 acfm. Pressures for all two-stage tandem models range from 100 to 175 psig.
