Electrical Vacuum Evaporator-Crystallizer by Heat Pump

The DESALT LT DRY series vacuum evaporator-crystallizer is designed to produce solid or semi-solid concentrates, as well as to recover valuable raw materials, such as metals and salts. The equipment operates with electrical energy and its heating and condensation system is based on a heat pump (HP) unit.

This evaporator can be manufactured with a screw conveyor inside the evaporation vessel to homogenize the product during the concentration phase, which facilitates the automatic discharge of the final product.

The operation of the equipment is semi-automatic or automatic (depending on the model) - 24 hours a day.
