Multi Effect Evaporator

Sn Aqua System involved in offering the wide range of multi effect evaporators. The multiple-effect configuration combines two or more evaporator bodies to conserve steam, which is condensed in the first-effect heat exchanger only. Water evaporated in the first-effect vapor body is condensed in the second-effect heat exchanger, which provides energy for evaporation in the second-effect vapor body (and so on for additional effects). Vapor from the last effect flows to a condenser.




The last-effect vapor body is maintained at a high vacuum with a steam-jet air ejector or mechanical vacuum pump. The driving force is the pressure drop from the first to the last effect.

For the same overall pressure differential and process conditions, the evaporator with more effects will require less steam. 

The chief factor influencing the economy of an evaporator system is the number of effects. By increasing the number of effects we can increase the economy of an evaporator system. The first effect of a multiple effect evaporator is the effect to which the raw steam is fed, vapors obtained from first effect act as a heating medium for another effect.



We offer the following MEE:

  • Forced Circulation Evaporators
  • Falling Film Evaporators
  • Rising Film Evaporators
  • Hybrid or Combination Evaporators
