Vacuum Technology
Combined steam jet and LRVP ( liquid ring vacuum pump) systems, often called hybrid systems, are based on proven jet pump technology and often used to create and maintain the vacuum.
Jet vacuum pumps are used to create and maintain the vacuum in evaporators, driers, in distillation and rectification plants, and in the processes of freeze drying, poly-condensation, degassing and deodorizing.
These sorts of equipment consist fundamentally of jet pumps and condensers or of a combination with other vacuum pumps such as, e.g. liquid ring vacuum pumps.
Generally, multi-stage vacuum pumps are used for suction pressures under 100 mbar. For the most effective use of energy, the motive medium and the condensable compounds are condensed between two stages.
The condensation pressure depends on the temperature of the cooling medium and characteristics of the motive medium. If you use water vapor as motive medium and if you have cooling water of 25 °C available, this pressure will be around 60 mbar.
Surface condensers are usually preferred as inter condensers to avoid any possible contamination of the cooling water with the suction medium.
Steam jet cooling systems are based on proven jet pump technology and often used to cool a liquid directly without any additional refrigerant by means of flashing into the vacuum.
With state-of-the-art pilot plants and test benches our R & D Center is optimally equipped for testing in the fields of jet pumps and vacuum systems.
Multi-stage steam jet vacuum pumps are used to produce vacuum in evaporators, driers, distillation plants, rectifying, freeze drying, poly-condensation, degassing, deodorizing plants etc.
