1. Allows you to reuse the energy of low pressure steam by increasing the steam pressure to a higher one.

2. No external power supply is required, which allows it to be used in hazardous areas (complete with GP-1000 / GP-2000 valve).

3. When used in combination with a condensate collection and return station, a separate condensate tank is not required: at the beginning, the condensate pressure drops to atmospheric pressure, then the flash steam pressure rises.

4. The system includes a highly efficient steam compressor.

5. The pressure control valve is operated on dry steam, because it has a built-in separator and steam trap, so the compressor has a long service life and always a stable steam pressure at the outlet.

A steam jet ejector is a device designed to move or mix media without the use of electrical energy.

Steam ejectorThe principle of operation is based on the supply of a working medium with high pressure to the nozzle of the discharge pipe, due to the narrowing of the flow in the nozzle, the speed of the medium increases to supercritical values, the flow is ejected into the suction chamber, where there is a sharp decrease pressure to form a vacuum. Due to the rarefaction, a secondary medium with a lower pressure (ejected medium) is sucked through the low-pressure nozzle into the suction chamber. Two media with different velocities but the same pressure enter the mixing chamber. The shape of the mixing chamber depends on the design velocity of the media. If the flow rate of the resulting media flow is subcritical, then the chamber is made of a cylindrical shape, if the flow rate is supercritical, then the chamber will have a conical shape with a narrowing along the flow in order to achieve a slowdown in the flow rate and effective mixing. Further, the total flow enters the input of the expanding part of the channel (diffuser), the flow velocity lies in the subcritical region, i.e. speed decreases and pressure begins to increase. The output from the ejector receives a stabilized homogeneous flow with a pressure lower than the pressure one, but higher than the low pressure one.

Steam ejectors are used wherever it is necessary to provide processes running at pressures other than atmospheric in a wide range of pressures, up to deep vacuum. These are the chemical and pharmaceutical industries, the food industry and others.

Examples of processes: evaporation intensification, crystallization, deodorization and deaeration, drying of substances, filtration and many others.
