The ENVIDEST LT FC-2 series vacuum evaporator is designed to treat aqueous-based streams with a low contaminant load. The equipment operates with electrical energy and its heating and condensation system is based on a heat pump (HP) unit.

The forced circulation technology enables the treatment of slightly more scaling streams than those managed by heat pump evaporators with submerged heat exchangers. It stands out for its energy efficiency: as a double-effect system, it utilizes the latent heat of generated vapour in the first effect to heat the liquid in the second effect, thereby reducing the energy consumed.

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