Multiple-effect vacuum evaporators (two phases).

ENVIDEST DPM-2 (8.000-20.000) is a vacuum evaporator which works by means of a submerged tube bundle exchanger with hot water and steam. Two condensation options: by evaporative condenser or plate exchanger with cooling water circuit.

Possibility of using the heat in several effects. Fully automated operation of the equipment. These evaporator equipment are created to concentrate the high effluent flows.

Our evaporators ENVIDEST DPM 2

Main features

  • Double effect evaporator fixed on frame.
  • Two steam boilers made of AISI-316 L stainless steel, of horizontal development with top registration point easy to access.
  • Two tube bundle exchangers, both submerged inside the boiler, made of AISI -316 L stainless steel. Exchanger removable by means of a flange, for its inspection and cleaning.
