Steam vs. Water Ejectors

Posted by Baelz North America | Mar 4, 2022 10:51:04 AM 1 Comment

Ejectors are small units within a heated fluid system that can distribute that fluid evenly throughout a defined area. Ejectors work without pumps; they use the Venturi principle to release and distribute either steam or heated water (depending on the system). At Baelz North America, we supply controllable pneumatic and electric ejectors, which each have a suction inlet, motive inlet, and discharge outlet arranged as a three-way valve to discharge the fluid. Learn more about the differences between our steam and water ejectors for various systems.

Steam Ejectors vs. Water Ejectors

Steam ejectors and water ejectors from Baelz NA are both controllable ejectors that can reliably and consistently distribute fluid throughout an area. Our steam ejectors are primarily used in these applications:
  • In recirculation systems that reduce the total energy consumption of a machine system
  • In compression systems that can save between 10-30% of generated steam in a system
These tools convert high-pressure steam into velocity, which creates a controlled vacuum to pull a flow of steam throughout the machine system with less energy consumption. By improving machine performance and saving energy, steam ejectors can help organizations save money. These ejectors are made with six key parts: a steam chest, suction chamber, steam nozzle, inlet diffuser, throat section and outlet diffuser. Steam ejectors are often used in:
  • Commercial and industrial bakery ovens
  • Fertilizer processing
  • Oil distillation, deodorization, and other petrochemical applications
  • District Heating and Cooling (HVAC)
  • Textile and paper drum dryers

Water ejectors also help facilities save electrical energy. They can replace water control valves in high-pressure systems to reduce energy consumption in heating and ventilation systems. Water ejectors can also control the circulation of fluid in a system and maintain temperature. Water ejectors can be slightly more simple than steam ejectors; rather than being a three-way valve with a special steam ejector plug, these tools have a motive chest, suction chamber, motive nozzle, diffuser, and actuator through which the fluid moves.

Water ejectors are commonly used in conveyance systems for pumping and mixing fluids, for HVAC and water heating applications in commercial, industrial, and municipal buildings, and in research and development.

For both types of fluid ejectors, it’s important to choose the right tool for a given application. At Baelz NA, we can help you determine the right steam or water ejector based on the size requirements, primary steam pressure, low-pressure steam levels, and other factors.
