The vacuum evaporator ENVIDEST LT VS series is designed to treat industrial liquid effluents. The equipment operates with electrical energy. Its heating and condensation system is based on a heat pump unit.

Standard manufacturing in 1.4401/1.4404 (AISI 316/AISI 316L) stainless steel. According to the wastewater to be treated, the parts of the equipment in contact with the fluid can be made of special corrosion-resistant alloys.

Fully automatic operation of the equipment 24 hours a day.

Main features

  • Vessel:A detachable vertical evaporation vessel, manufactured in stainless steel. Equipped with a manhole and an inspection glass.
  • Submersible heat exchanger: The evaporation vessel houses in its flanged lower section a coil-type stainless-steel heat exchanger to heat the product to be concentrated.
  • Condensation section: A coil-type stainless-steel heat exchanger is positioned in the flanged upper section of the vessel and is intended for the condensation of the vapour produced.
  • Demister, located between the evaporation and condensation zones, to capture droplets of the wastewater within the vapour produced.
  • Distillate tank: The distillate is stored in a stainless-steel tank and is discharged by a centrifugal pump controlled by level switches. Depending on the model, it is either an option or already included in the standard configuration.
  • Heat pump unit uses the refrigeration cycle to heat the wastewater and condense the vapour produced, as well as to cool the vacuum circuit. It consists of a compressor using an environmentally friendly refrigerant, R-407C freon gas, a thermostatic expansion valve to regulate the refrigerant pressure, and fans for reducing the refrigerant temperature.
  • Vacuum generation system consists of a Venturi ejector and a centrifugal pump or a liquid ring vacuum pump (depending on the model) and a stainless-steel vacuum tank containing chilled water to cool the vacuum circuit. The vacuum tank is equipped with a coil-type heat exchanger through which the refrigerant circulates.
  • Concentrate discharge: Recirculation and automatic discharge of concentrate through the recirculation pump. The duration of the concentration cycle is programmed with a timer.
  • Instrumentation: Digital and analogue control instruments for the automatic monitoring of the system.
  • Electrical command and control panel with emergency stop. IP54/IP55 protection (depending on the model). The power supply of the panel is 400 V, 50 Hz. Siemens PLC with touch screen for visualization and control of operating data.
  • Supporting structure: Unit mounted on a stainless-steel skid.

Optional features

  • Teleservice Control System for remote assistance.
  • Manufacturing with special material on request.
  • Other voltage supply on request.
  • Other PLC manufacturer on request.
