From

1

Evaporator distillation throughput from 10 to 750 L/hour. Low temperature vacuum evaporator with heat pump, powered with electrical energy. Suitable evaporator for die-casting, electronic and mechanic industries, heat treatment, eluates from resin regeneration RO rejects, food & beverage (electropolished evaporator version available on demand), chemical & pharmaceutical, galvanizing, pickling and surface treatments, paint industry, printing industry, engraving, printing rotogravure, packaging, wineries (special line for the grape must concentration). Detachable evaporator boiling vessel, submersed heat exchanger, large manway and sight glass with illuminator, built-in condensation section, full automatic operation with PLC and touch screen. Automatic cleaning. Standard manufacturing in 1.4401/1.4404 (AISI316/316L) or special alloys for hazardous liquids.

  • VS HP series is particularly suitable for:
  • oily emulsions, wastewater from vibratoryfinishing, exhausted baths
  • wastewater from pressure die-casting (release agents, glycols, lubricant oils)
  • wastewater from galvanization (chromium, nickel, copper), exhausted baths, eluates
  • recycling of exhausted baths
  • treatment of all water-based solutions

  • En-bloc skid made of austenitic steel.
  • Boiling vessel, fitted with low-side flanged section for the housing of toroidal heat exchanger, complete with manhole and inspection sight glass.
  • Digital and analogue control instrument for the automatic monitoring of the system.
  • The upper steam condensation section is complete with heat exchanger and cooling circuit.

  • Automatic circuit for condensate discharge and vacuum generation, composed of centrifugal pump, Venturi ejector, condensate storage and cooling tank, complete with heat exchanger, check valves, digital and analogue control, monitoring instrument.

  • The evaporator cooling unit features a heat pump made by a main refrigerant unit, complete with process compressor, eco-friendly driven, sub-cooling battery, heater fans, filters, pressure switches, pressure senders, gas flow indicators, de-super-heater.
  • Additional cooling unit (from model ECO 1500 VS-HP) complete with auxiliary compressor, control equipment, filters.
  • Speed control system for undercooling fans (standard supply from model ECO 3000 VSHP).

  • Automatic circuit for recirculation and discharge of the concentrate, complete with extraction pump, pneumatic and manual shut-off valves for taking product samples during processing.
  • The automatic discharge function is programmable through an adjustable density control device or by a timer for a complete customization of the process.

  • The automatic evaporator cleaning system is complete with pneumatic valve and rotating nozzle. The circuit allows the release of cleaning agents inside the evaporator: the wash cycle time can be adjusted from the control panel according to the actual needs.

  • Automatic system complete with foam formation sensor and variable setting control. The circuit allows the automatic injection of antifoam products inside the evaporator: the quantity of injected antifoam is adjustable by the control panel according to the actual needs.
