Geothermal energy production exploits steam, brine, and hot water reservoirs heated by dry rock or magma below the Earth’s surface. Considered a sustainable resource, geothermal power is popular in countries like the United States, the Philippines, and Indonesia, where plants produce hundreds of megawatts of capacity. Regions of Latin America, South America, Africa, and the Middle East are in the planning and development stage for additional generation for the future. The two most common plant types are flash steam, which uses naturally occurring steam to power a turbine, and binary steam, which uses the hydrothermal reserve to heat a working medium, such as Isopentane or Isobutane.
Generating geothermal electricity requires high reliability and precise control in challenging environmental conditions. REXA Linear and Rotary Actuators are field-proven for geothermal energy production applications such as steam turbine governor and trip applications, production well/injection well steam control and isolation, pump protection, and heat transfer fluid loops. Maximized uptime is the key economic driver for these plants.
REXA Electraulic Actuation™ offers high reliability, low power consumption, and durability in harsh conditions and extreme heat, allowing plants to achieve their economic goals.
