Steam ejectors

Steam ejectors use a gaseous medium for propulsion. The propulsion flow is greatly accelerated in the nozzle, thereby generating a negative pressure that causes a suction flow. Both flows are mixed, whereby kinetic and thermal energy is exchanged. The mixture exits the ejector via the third port.

The functional principle of the regulated ejector is also applicable for steam.

Our steam ejector pumps permit steam to be recirculated and compressed to improve machine performance, thereby also saving a lot of energy. The systems are reliable and run quietly. System availability, manufacturing reliability, energy costs, and maintenance expense are key factors for the success of every industrial field.

Advantages at a glance
  • Increase in the effective heating surface
  • Reduction of steam loss
  • Increase in machine performance
  • Applicable to all types of steam systems
  • Enables full use of available energy

Steam ejectors can be applied in two different types of system:

1. Recirculation

Chose this type of installation if you want to improve the performance and thus the productivity of your machines. This can help increase the average performance by 15% with steam savings of up to 5%.

2. Compression

Our purpose-built steam ejector installations are designed to save energy, achieving direct steam savings from 10 to 30% and even more.
