Functional description
The TS system performs all the basic functions of a buffer/barrier system for dual seal operation:
– Pressure-build-up in the seal chamber
– Leakage compensation
– Circulation of the buffer/barrier fluid by thermosiphon effect or forced circulation
– Cooling of the seal
– Selective absorption of product leakage and prevention of dry running (tandem arrangement). When pressurized, this is provided via compressed air or nitrogen.

1) Design data, permissible working values depend on the operation conditions.
2) Low Flow: 8 l/min (process fluid), 10 l/min (cooling water), △T = 40 K
3) High Flow: 15 l/min (process fluid), 20 l/min (cooling water), △T = 40 K
