Increase reliability, protect critical assets and stabilise power output

Power generation equipment operates under high thermal and mechanical stress, where particles, moisture, and oxidation by-products accelerate wear, reduce efficiency, and increase the risk of unplanned outages.


By keeping oil clean and dry, CJC® helps power plants control contamination, stabilise operation, extend component life, and reduce stoppages.

Why power systems fail

Power plants depend on precise lubrication and hydraulic control. When contamination builds up, system stability declines and small issues quickly turn into costly failures.

Valve symbol representing fluid control and system flow regulation.
Sticking control valves

Valve spools begin to seize when particles and varnish accumulate, causing unstable turbine control and delays in response.

Gear with exclamation mark representing system warning or critical condition.
Accelerated bearing and gear wear

Abrasive particles erode metal surfaces, increasing vibration and shortening the life of critical rotating components.

Thermometer symbol representing heat and temperature monitoring.
Gearbox overheating and reduced efficiency

Contaminated oil loses its lubricating and cooling ability, allowing heat to build up and lowering system efficiency.

Unplanned outages and derated output

Escalating contamination leads to reliability issues that force production drops or sudden shutdowns, costing thousands per hour in lost generation.

Across power plants, the reliability of turbines, gearboxes and hydraulic control systems depends on the condition of the oil circulating through them. Yet oil is often managed as a routine maintenance item rather than a critical performance factor. In reality, contamination builds continuously as particles, moisture and oxidation by products gradually turn lubrication and control oils into sources of wear, heat and instability that undermine efficiency and increase the risk of failure.

Oil filtration that keeps your power plant running

Offline filtration that removes particles, water and oxidation residues to keep turbines, gearboxes and hydraulic systems efficient and reduce unplanned stops.

Key operational benefits

Higher system reliability - Clean oil reduces sticking valves and wear, helping turbines, gearboxes and hydraulic systems operate consistently.

Longer component lifetime - Removing particles and water slows mechanical wear, extending the life of bearings, gears and pumps.

Fewer unplanned outages - Continuous contamination control prevents the failures that force unexpected shutdowns and production losses.

Longer oil life and lower operating costs - Dry, particle-free oil degrades more slowly, reducing oil changes, waste volume and overall maintenance spend.

More stable thermal behaviour in critical systems

Clean oil improves heat transfer and reduces insulation effects from oxidation deposits, helping turbines, gearboxes and auxiliary systems operate within designed temperature ranges.

More predictable maintenance planning and execution

When oil condition remains stable, maintenance activities shift from reactive interventions to planned tasks, improving scheduling, manpower use and outage coordination.

Improved control accuracy and system responsiveness

Reducing fine contamination and moisture supports smoother valve movement and actuator response, improving control performance during load changes and start-up sequences.

Applications across your power generation systems

Power transmission towers and cooling towers at a thermal power plant, representing turbine lubrication systems where clean oil and effective oil filtration reduce oxidation, water ingress, and varnish formation to ensure stable operation.

  • Turbine lubrication systems

    Challenge: Oxidation residues, heat and water ingress cause varnish formation and sticking control valves.

    Result: Cleaner, dry oil improves valve response, stabilises turbine operation and reduces the risk of derating or shutdown.

  • Hydraulic actuation & control systems

    Challenge: Fine particles and moisture lead to sluggish valve movement, internal leakage and erratic system behaviour.

    Result: Stable oil condition improves accuracy and reliability of actuators and control valves across the plant.

  • Gearboxes (cooling towers, feed systems, auxiliary drives)

    Challenge: Wear particles and water accelerate tooth and bearing wear, causing vibration and overheating.

    Result: Reduced wear and lower temperatures extend gearbox lifetime and reduce the need for corrective maintenance.

  • Pumps and compressor lubrication systems

    Challenge: Contaminants accumulate in lube circuits, increasing friction, seal wear and energy losses.

    Result: Cleaner oil improves lubrication film stability, lowers energy consumption and reduces component wear.

  • Transformers & insulating oil systems

    Challenge: Moisture reduces dielectric strength, accelerates ageing and increases the risk of insulation breakdown.

    Result: Lower water content maintains oil integrity, supports reliable electrical performance and prolongs transformer life.
