Mechanical vapour recompression evaporators with forced circulation, external shell and tube heat exchanger.
Overview
The RV F series evaporators have a heating system based on the mechanical vapor recompression (MVR) principle, and operate under a small vacuum at 70 kPa and around 90°C (194°F). The evaporators require only an electrical power supply. The RV F series, like the PC F and PC R series, does not require any external heating and cooling system.
Heat exchange occurs within an external shell and tube exchanger where the hot vapor coming from the compressor increases circulating wastewater temperature. Subsequently, in the boiling chamber, boiling wastewater produces new vapor that is compressed by the compressor before flowing to the shell side of the heat exchanger. This particular configuration is designed to minimize power consumption.
The RV F series production capacity varies from 10,000 to 120,000 liters of distillate per day.
As in all EVALED® evaporators, the evaporation process is controlled by a PLC that controls the wastewater-to-be-treated automatic feed and the distillate and concentrates discharge, requiring only minimum supervision by the operator.
The RV F series are particularly suitable for:
- Mechanical, steel & automotive industry
- Galvanic & surface treatments industry
- Graphic arts
- Energy
- Landfills & waste disposal
