Our steam jet systems have a simple design, they are reliable and require low maintenance.
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.
