Application
A thickening vessel fitted with a scraper is used to increase the concentration of extracted solutions by means of evaporation under vacuum. Extremely precise level measurement is required in this process because the concentration is determined by the filling height. The evaporation system operates according to meeting specified levels. As soon as they reach the correct value, the evaporation process is stopped and the concentrated solution is discharged out of the tank.
Your benefit
Reliable
Optimal concentration thanks to highly accurate level measurement
Cost effective
Easy cleaning without dismantling
User friendly
Simple installation and setup
