Profile
Rexa's Electraulic™ Technology is a revolutionary brand of electro-hydraulic actuation. It combines the simplicity of electric operation, the power of hydraulics, the reliability of solid-state electronics, and the flexibility of user-configured control.
Established in 1981, Rexa focuses on upgrading applications where the existing final control element is the limiting factor in process control loop performance and reliability. Impactful ROI has been realized in major industries including: O&G upstream/midstream/downstream, Power generation, Metals and Mining, Water/Wastewater. With 30 years of field experience upgrading in these industries, the Product and Company are mature. Considering our field experience and continuous innovative engineering we are now on our third-generation product. We look to eliminate unnecessary oscillations or instabilities, and control loop 'compromises' resulting from inherent performance limitations of more traditional actuator technologies. Rexa is also implemented to eliminate costly trips, maximize throughput and optimize efficiency.
Self-contained electrohydraulic actuators are compact, powerful and respond to control commands in milliseconds with zero overshoot. When no movement is called for, there is no energy consumption. Representing a technological breakthrough in fluid circuitry, Rexa actuators eliminate the need for reservoir tanks, EHC systems and periodic oil and filter maintenance associated with traditional hydraulic systems. Rexa actuators enable significant performance improvements over current best practice specifications in many applications and deliver rapid ROI, particularly in fast acting control loops: pressure, flow, combustion, turbine speed.
Examples of Rexa applications include: Rotating Equipment – Steam Turbine Speed, Inlet Guide Vane, Fuel Gas, Compressor Anti-Surge: Control Valves – High pressure drop, rapid strokes, precise small step response and stability, overcoming friction, stiction, slurry buildup: Combustion Efficiency – stack dampers, O2control.
