a common mineral-based turbine oil shows a 9% higher heat capacity for the SPE based fluid across the expected operational temperatures for a hydro turbine. (Figure 6) This suggests the frictional or heat management performance (or both) are superior for the new fluid, and this is considered to be the primary reason why a lower fluid temperature was observed in this trial. This observation could have much broader implications across our industry for those equipment users that are searching for improved heat management solutions.
Figure 6: Volumetric Heat Capacities of Hydropower Turbine Oils. Summary
New turbine oil technology has emerged to support the global shift towards sustainable industrial operations. Implementing VBASE®
Hydro T-EL
into service represents a high-value innovation. For hydropower operators, it provides a practical, risk-mitigating path to achieving sustainability goals while maintaining peak turbine performance.
