Vacuum is used for distillation, drying, degassing, filling and boiling.
PLC compact vacuum unit
The compact vacuum unit consists of a liquid ring vacuum pump, liquid separator and various instruments such as heat exchangers, valves, ejector etc.
The pump works according to the liquid ring principle. Liquid ring pumps are in some regards related with displacement pumps since the pump wheel is eccentrically located in the round pump body. When the wheel is rotating a fluid ring is created along the pump body's inner wall. In the cells (the space between the pump body's wings) inside the fluid ring rising part volumes (intake) and then decreasing volumes (outlet) will be created under one rotation.
The PLC vacuum system is available in three different variants:
Operation mode H: Circulation operation
Operation mode T: Combined operation, thermostatic control
Operation mode C: Combined liquid operation
