Developed by the American engineering firm Thomson-Houston, Turbo Unit No. IV was commissioned to augment the plant’s overall generation capacity. The turbine, rated at 16,000 horsepower, was designed to operate under a steam pressure of 40 kg/cm² and at temperatures ranging from 420 to 450 °C.
At the center of the unit lies a 12,500 kVA alternator, delivering output at 1,050 volts with high operational efficiency. Surrounding instrumentation—including regulators, pressure gauges, oil pumps, and signal panels—ensures the stable and secure operation of the turbine assembly.
The condensation system comprises two large bronze condensers, ejectors, coolers, and high-capacity water pumps, enabling efficient condensation and thermal regulation. Auxiliary systems—such as lubrication modules, motor assemblies, and maintenance equipment—further enhance the unit’s operational resilience.
Recognized as one of the most robust production units in the facility, Turbo Unit No. IV provided continuous and reliable electricity generation, even under high load conditions. Today, it remains on public display in its original location, serving as a tangible exemplar of early American steam turbine technology.
