Ejectors

Ejectors can be used wherever the main pump generates sufficient differential pressure. According to VDI 2067, conventional circulation pumps have a lifetime of 10 years, whereas ejectors have a lifetime of 20 years. Ejectors are frequently used in the energy sector, in heating, hot water, and ventilation system applications. Baelz ejectors can be utilized with pneumatic or electric actuator options.

Ejectors are an energy-efficient process solution that ensures an efficient flow of energy through heat transfer fluids. Ejectors will provide distribution and the exact amount of heated water over dozens of circuits without the use of a pump. Based on Bernoulli's equation and the Venturi principle, the kinetic energy of water is conserved and is not wasted like a typical 3-way valve application.

Baelz NA offers controllable nozzle water and steam ejectors. A controllable nozzle ejector is a 3-way control valve with intrinsic suction power. These ejectors have a motive inlet, suction inlet, and discharge outlet on the bottom.

Water Ejectors Baelz-Hydrodynamic®

Water Ejector

The controllable water ejector combines the functions of four single components: It generates circulation in the area of the consumer, it adjusts the circulation volume according to the actual heat requirement, it regulates the temperature and compensates for fluctuations in differential pressure.

Saving electrical energy through energy-efficient equipment and installations is becoming increasingly important. Where heating water would usually be distributed to secondary circuits using a control valve and a pump for each circuit, Baelz uses controlled ejector technology.

Many of our heating and ventilation systems have been in operation for over 30 years, saving energy and money.

Advantages at a Glance

  • Good controllability over the entire load range
  • Only one main pump, meaning lower energy costs
  • Simplified system design due to fewer components
  • Less data points in the higher-level control system
  • Lower return temperatures
  • Hydraulic stability

Steam Ejectors Baelz-Vapordynamic®

Steam Ejectors

The functional principle of the regulated ejector is also applicable for steam. Here, smooth-running equipment is of the essence. Factors such as production reliability, energy costs and maintenance expenditure are crucial for success in all industries.

Advantages at a Glance

  • Increase in the effective heating surface to 100%
  • Reduction of steam loss
  • Increase in machine performance
  • Applicable to all types of steam systems
  • Enables full use of available energy
