Functional description
- The TS system performs all the basic functions of a barrier/buffer system for the operation of dual seals
- To pressurize the barrier/buffer chamber
- As leakage compensation
- Barrier/buffer fluid is circulated by thermosiphon effect or forced circulation system
- To cool the seal
- To selectively absorb product leakage and prevent dry running (tandem arrangement) Use nitrogen for pressurization; pressurization is monitored by a pressure transmitter (default). The incorporated level transmitter issues a signal whenever the level of barrier/buffer fluid is too low.
