Main features

  • Steam boiler evaporator built in A-316 L, can be completely dismantled.
  • Internal scraper activated by a gear motor, made in A-316L, in order to avoid fouling and to improve the heat transmission and the consistency of the fluid to be treated.
  • External sleeve heat exchanger recovering the external side of the boiler.
  • High efficiency main circuit with main compressor for refrigerant heating and cooling(Ecological Freon gas type R407c or R134a).
  • Supporting circuit for cooling of the vacuum circuit with compressor and instruments.
  • Cooling axial fans with automatic insertion through pressure transducer.
  • Venturi system vacuum with liquid ring.
  • Concentrate discharge especially for very dense liquids, by means of a pressurisation system.
  • Control panel with display, to show the operating data and PLC SIEMENS integrated in the cabinet.
  • Automated cleaning system for the inside of the boiler. With cycle start from the operator.
  • Antifoam automated control and dosage system.

Optional features

  • Boiler in SAF 2507, SANICRO 28 (effluent with high levels of chloride and fluoride,etc).
  • Internal scraper built in SAF 2507, SANICRO 28 or TITANIUM (effluent with high levels of chloride and fluoride, etc).
  • Distillate trap for collection and sorting of   solvents.
  • Special Teflon non-stick coating.
  • Antifoam automated control and dosage system(if needed).
