Steam jet heaters

Mode of operation

There are generally two different construction forms, according to the application:

• Steam jet heaters for vessels (aw1)
• Steam jet heaters for installation in pipes and for passage or circulation heating systems: 
  • Type “L” (aw4)
  • Type “H” (aw5)
  • “System Ciba-Geigy” (aw6)

Advantages

• Low noise operation
• No moving parts
• Low maintenance
• Simple construction
• High reliability
• Can be installed in virtually all situations
• Quickly and easily put into operation
• Adjustable heating capacity
• Almost unlimited life, when a suitable material of construction is chosen
• Can be manufactured from various materials of construction
• Low acquisition costs
  
   

Steam jet heaters are used to heat all kinds of liquids in vessels. Heating is achieved by means of direct condensation of steam. The steam condensate mixes with the liquid.

Mode of operation

The steam jet emerging from the motive nozzle accelerates the liquid present in its vicinity and in the mixing nozzle and condenses. In this way a controlled flow is produced. Furthermore, the whole content of the vessel is set in motion and the heat transferred to the liquid is evenly distributed throughout the vessel.

For Pipes (aw4, aw5, aw6)

Applications

Steam jet heaters are used to heat liquids by means of direct condensation of steam. The steam condensate mixes with the liquid. Steam jet heaters type “L” are used in passage and circulation heating systems. The achievable heating per pass amounts to max. 90 K.

Type "H" (aw5)

Applications

Steam jet heaters type “H” are used in passage and circulation heating systems:

• Heating to max. 30 K per pass
• Steam flow control range up to max. 5:1

"Ciba-Geigy" (aw6)

Applications

Steam jet heaters are used to directly heat a liquid with heating steam. Steam jet heaters, “System Ciba-Geigy”, are used in passage and circulating heating systems and for batch processes.
