Principle of Operation

The Thermocompressor is an ejector used when both motive and suction gases are steam. Thermocompressors have automatically-controlled spindles. They are used when pressure suction or discharge conditions vary and it is necessary to control discharge pressure or flow. Thermocompressor spindles are designed to act as temporary valves and provide tight shut-off. Thermocompressors are available in materials to fit operating conditions or as specified by the customer.

Fig. 426 Thermocompressors have automatically-controlled spindles. The spindle can be operated with a diaphragm, piston, or motor actuator using any standard instrument signal, either electric or pneumatic. The Fig. 439 Thermocompressor is the threaded-connection version of the Fig. 426.


Fig. 426 and Fig. 439 Thermocompressors are Automatic Jet Compressors that can be used in applications operating over a range of pressure and differential pressure. Thermocompressors may be utilized wherever available energy is being lost through reducing valves; such as high pressure steam reduced and desuperheated for process use and mixing of gases without use of mechanical compressors. Diaphragm and piston operators use any standard split or full range, electric, electronic, or pneumatic instrument signal. The control can be activated by temperature, pressure, flow, or suction to motive gas ratio.
