SMART™ Turbine Seals
EthosEnergy solves the problem of seal clearance damage and virtually eliminates seal-related efficiency losses with our patented SMART™ Retractable Brush Seals and Brush Tip Seals.
In a typical steam turbine, 50% of efficiency loss comes from seal clearance damage.
Retractable Packing has been installed in hundreds of units worldwide and prevents startup rubs. Further enhancements are now available to improve the unit performance over design. By measuring the rotors and seal holders, EthosEnergy can custom size the seals for your unit to ensure optimum performance. The retractable feature of this upgrade allows a large clearance for turbine start up where rubs typically occur, saving the seals for long term efficient operation.
The addition of Brush Seals to our Retractable Packing reduces the design clearance between the seal teeth and rotor shaft to “zero” and provides a MW benefit over original design.
