Electrical Vacuum Evaporator by Heat Pump
The ENVIDEST LT VS 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.
This equipment stands out for its superior energy efficiency within the range of single-effect heat pump evaporators. Thanks to its submersible coil-type heat exchanger, it has a larger exchange surface and requires less installation space.
The operation of the equipment is fully automatic - 24 hours a day.
