Multiple-effect vacuum evaporators (two phases).

ENVIDEST MFE-2 (10.000-120.000) is a vacuum evaporator with external heat exchanger and forced circulation. The equipment works with contribution of hot water or steam.
Two condensation options: by Air condenser or cooling water circuit plate exchanger.

Possibility of using the heat in several effects. Fully automated operation of the equipment.

Our evaporators ENVIDEST MFE 2

Main features

  • Double effect evaporator. Fixed on frame.
  • Two vertical steam boilers built in stainless steel, with easy access inspection manhole on the side, demister y heat insulation.
  • Two stainless steel external special heat exchangers of low fouling, with heat fluids inlet and outlet.
  • Two heating options for evaporation of first effect:
  • Steam circuit heat exchanger.
  • Superheated water circuit heat exchanger.
  • Two condensation options in the second effect:
  • Air condenser equipment.
  • Coolant circuit plate exchanger
  • Two recirculation centrifugal pumps with double seal in AISI 316.
  • Two distillate pumps, controlled by a level sensor.
  • Two separate vacuum systems operated by liquid ring pump.
  • System of aspiration of water to be treated by vacuum suction, controlled by the boiler’s inside level sensor which controls the inlet valve.
  • Two discharge pumps, controlled by time or density.
  • Antifoam measuring system: completely automated with foam detector. It allows the automatic injection of the antifoam product to the evaporator.
  • Anti-fouling dosage system, with metering pump.
  • Integrated electric panel. Control system with PLC SIEMENS S7-300 and HMI SIEMENS MP377.
  • Communication system with remote assistance modem (optional).
  • Power supply: 400 V III, 50 Hz.

Optional features

  • Parts of the equipment touching the fluid built with special material corrosion resistant (SAF 2507, SANICRO 28, TITANIUM or stainless steel austenitic-ferritic super duplex alloys) (for effluents with high levels of chloride, fluoride, etc. Remote management MODEM.
  • Other power supplies available.
