Generators provide energy by transforming kinetic energy from turbines into electrical energy. A byproduct of this process is heat, which results in the need for cooling the generator. This is especially so in the case of large power generators. One highly efficient cooling process for large power generators involves the use of Hydrogen (H2). This gas has very good heat removal properties when used as a coolant. However, it is also a highly explosive gas.

We provide safe flange-type penetrations for instrumentation and control purpose, as well as thermocouple penetrations or combinations of both, to enable the productivity of energy facilities for many decades.

SCHOTT Eternaloc® penetration modules for energy generators consist mainly of:
  • A steel flange with nickel-iron conductors sealed in by means of compression-seal technique
  • standard penetrations ranging from 1 to 406 conductors, allow an optimized construction of the generator’s vessel
  • standard thermo-couple penetrations up to 121 thermo-couples
  • sealing between the penetration and the generator, usually accomplished by an o-ring
