Multiple-effect vacuum evaporators (one phase).

ENVIDEST DPM-1 (4.000-10.000) 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 1

Main features
