Hydel Plant Turbine Oil Filtration Systems

In small hydel power plants, turbine oil is the lifeline of both the turbine bearings and the hydraulic governing system. Despite its critical role, oil contamination is often overlooked until failures occur.

The RFSE 5 00 and RFSE 10 00 built with Japanese collaboration are compact offline turbine oil filtration machines designed for Hydel Power plant turbine lubrication circuits, Hydraulic applications and small volume Transformer oil.

Problems that can happen:

• Hydel turbine facing bearing overheating and erratic guide vane control.
• Moisture ingress through seals and condensation.
• Fine particles blocking servo valve ports.
• Sludge deposits from oxidized oil.
• Bearings wear out, temperature increases.
• Leads to unplanned downtime for flushing and repairs.

Servo valve failures are not caused by design flaws, but by fine particle contamination. By integrating advanced bypass filtration, RTES ensures stable valve performance, longer oil life, and reduced maintenance costs.

Root Cause

No continuous oil filtration & water removal. Ignoring oil contamination = downtime & reduced power output, erratic control, forced shutdowns and costly energy losses.

Solution: Keep the Turbine Oil Clean & Dry

1. Particle contamination – use of RTES depth filtration machine to remove micronic contamination.
2. Moisture contamination – our depth filters also absorb moisture in oil.
3. Proactive maintenance step – install an offline RTES filtration system for continuous cleaning.

Advantage: Restores OEM-Grade Oil Cleanliness – Dedicated M/C Application

• Reliability: Turbines run longer between service intervals.
• Efficiency: Higher power output with fewer interruptions.
• ROI: Reduced unplanned maintenance translates into measurable cost savings.
