(1)Features

• Uni-directional or bi-directional
• Elastomer-free
• Ready-to-fit cartridge unit
• Single seal available
(2)Advantages
The gas seal for single stage steam turbines. The amount
of steam leakage with the TDGS is only a fraction of that
occurring with carbon ring seals, leading both to energy
savings and an increase in the operating efficiency of the
turbine. Bearing oil is no longer contaminated with
condensed steam, which increases the service life of the
bearings and results in a corresponding drop in
maintenance costs.
