The DEPAC TS Thermosyphon system is a simple and reliable support system for double seals. It can be used with DEPAC double seals as well as those of other manufacturers.

The barrier fluid should be a low viscosity, well lubricated and clean liquid with a high specific heat capacity

Due to pipe resistance, the viscosity of the barrier fluid should not be much higher than that of water.
If for safety, technical and / or product reasons, the barrier pressure must be higher than the medium pressure, then an appropriate nitrogen buffer may be applied to pressurize the barrier fluid.

To ensure the best possible circulation, it is always recommended to use a cooling system with cooling coils within the TS-tank.

Multiple Connections
If one thermosyphon system is to be used for two seals, a circulation pump must be used in the barrier fluid line.
