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 (W) and steam (V). Two condensation options: by wet-bulb condenser (C) or plate exchanger with cooling water circuit (W).
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
- 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.
- Two heating choices for evaporation on first effect:
- Wet-bulb condenser (C), stainless steel box, closed circuit of cooling water with automatic fill-in valve, circulation pump with spraying mouthpieces. High flow fan cross-current.
- Plate exchanger with cooling water circuit (W).
- Venturi vacuum system.
- Recirculation pump / download of special concentrate for dense liquids.
