Defon provides highly efficient built-in bearing oil coolers for hydro turbines. Featuring a compact embedded structure and enhanced heat transfer tube bundles, our coolers offer excellent installation fit, uniform heat dissipation, and strong vibration resistance. They ensure long-term, stable control of bearing oil temperatures, perfectly adapting to the confined installation spaces of hydro turbines.
Performance: Features proprietary enhanced heat transfer and anti-blocking turbulent flow structures, perfectly suited for high-load bearings in large-scale hydro turbines (e.g., Baihetan Hydropower Station).
Structure: Shell-less design that integrates seamlessly into the bearing oil reservoir without occupying extra space.
Reliability: Rigorously tested with hydrostatic pressure and non-destructive testing (NDT) to completely prevent leakage. Available in oil-resistant and high-temperature materials to withstand harsh operating conditions.
Maintainability: Optimized tube spacing and fin design (smooth tube/low-fin options) prevent scaling on the water side and sludge accumulation on the oil side, eliminating the need for frequent cleaning.
Versatility: Covers upper guide, lower guide, turbine guide, and thrust bearings, compatible with generating units ranging from 10 MW to 1,000 MW.
