Fox multi-stage vacuum systems are in service maintaining vacuum on towers and reactors in the process industries. Installations include distillation processes, vegetable oil deodorizers, evaporators, and crystallizers.

Fox vacuum systems can have two, three, four, or five ejector stages and as many pre-, inter-, and after-condensers as are required. The schematic above shows a three stage system with two surface condensers.

Skid-Mounted Packages Fox Valve can skid-mount turnkey systems , as shown at right. These can include valves, instrumentation, steam headers, controls, etc.

This schematic shows a three stage system with direct contact, or barometric, condensers.

This schematic shows the contents of an agitated, jacketed vessel being cooled by a skid-mounted, 3-stage ejector system.
