Description
The Serenity Wind Square Root blade spring tube upgrade for the E-3120 addresses common OEM weaknesses such as spring buckling, excessive noise, and premature wear. Its advanced design ensures quieter, smoother operation and maintains proper spring function under overspeed conditions.
Each set of spring tubes are calibrated to the blade weight and centre of gravity. This ensures the spring tube does not deploy in normal generation thereby maintaining power production. Endurance spring tubes are known to deploy prematurely reducing generation. Conversely, endurance spring tubes are known to deploy late resulting in higher rpm during a brake failure event.
UK-designed and manufactured from high-quality materials, this upgrade increases turbine reliability, simplifies maintenance, and extends operational life for Endurance E-3120 turbines.
