Almatec Chamber Barrier
The Almatec Barrier system provides increased liquid containment and an alarm if this is breached.
The single diaphragm is replaced by a tandem arrangement of two diaphragms and a barrier chamber of conductive PE in between. The barrier chamber is standard-wise filled with a non-conductive liquid (Deionised water). On request the barrier chamber can also be filled with a conductive liquid (for instance a water-glycol-mixture). To ensure the correct transfer of the pressure from the driving air, the barrier chambers have to be filled completely. Therefore, they are monitored by liquid sensors. After loosening the plug the barrier liquid can be refilled.
