Electrical Vacuum Evaporator-Crystallizer by Heat Pump

The DESALT LT VR series vacuum evaporator-crystalliser is designed for the treatment of scaling aqueous based streams, as well as for achieving high product concentration. The equipment operates with electrical energy and its heating and condensation system is based on a heat pump (HP) unit.

Equipped with an internal motorised scraper, the evaporator ensures continuous cleaning of the heat exchange surface in the evaporation vessel, preventing the formation of scale. It allows the precipitation of crystals from dissolved solids by increasing the concentration above the solubility limit.

The operation of the equipment is fully automatic - 24 hours a day.
