Steam Jet Ejector System Solutions:
Designed for Your Vacuum Requirements
Schutte & Koerting manufactures a complete range of steam ejector vacuum system configurations from simple single-stage steam ejector designs to sophisticated multi-stage steam ejector assemblies with inter- and after-condensers. Each steam jet vacuum system is custom-engineered to optimize performance, steam consumption, and operational economics for your specific process conditions.
Single-Stage
Steam Jet Ejectors
Single-stage steam ejector systems operate by converting steam pressure energy into velocity energy within a converging-diverging nozzle. The high-velocity steam jet creates a low-pressure zone that entrains air, gases, or vapors from the process equipment.
Multi-Stage
Steam Jet Ejector Systems
Multi-stage steam ejector systems with up to six stages achieve the deepest vacuum levels available from steam jet vacuum system technology. These sophisticated systems utilize multiple inter-condensers to progressively compress process gases from ultra-high vacuum to atmospheric discharge.
Steam Air Ejectors
Steam air ejector and steam jet air ejector systems are specifically designed for removing air and other non-condensable gases from surface condensers, barometric condensers, and process equipment. These specialized steam vacuum ejector configurations optimize performance.
Steam Jet Vacuum Systems with Condensers
Complete steam jet vacuum system packages integrate ejector stages with appropriately sized inter-condensers and after-condensers to maximize vacuum performance while minimizing steam and cooling water consumption.
Custom Engineered Systems
Tailored to pressure, temperature, and gas composition, every industrial process presents unique vacuum requirements. Our engineering team designs custom steam ejector vacuum system solutions optimized for your specific conditions.

How Steam Jet Ejectors Work: Simple, Robust Vacuum Generation
Understanding steam jet ejector operating principles helps optimize system selection and performance for your vacuum applications.
- High-Pressure Steam Supply - Saturated or superheated steam at elevated pressure enters the steam jet vacuum ejector.
- Nozzle Expansion - Steam expands through a converging-diverging nozzle, converting pressure energy to kinetic energy.
- High-Velocity Steam Jet - Steam accelerates to supersonic velocity, creating extremely high kinetic energy.
- Suction Zone Creation - The high-velocity steam jet creates a low-pressure zone that entrains process gases and vapors.
- Gas Entrainment - Process gases from the vacuum system are drawn into and entrained by the steam jet.
- Mixing Section - Steam and entrained gases mix intimately in the venturi throat.
- Compression in Diffuser - The mixture decelerates in the diffuser, converting velocity energy back to pressure energy.
- Discharge - Compressed mixture discharges at elevated pressure to the condenser, next stage, or atmosphere.
