Parker’s new clearcurrent® ASSURE filters are best-in-class for advanced gas turbines
The Gas Turbine Filtration Division of Parker Hannifin Corporation – a global leader in motion and control technologies – has announced the launch of its clearcurrent® ASSURE filters for high-performance gas turbines.
All components within the latest advanced gas turbines must be able to withstand the harsh environments and multiple contaminates to which such systems are continuously exposed. Leveraging decades of filtration engineering experience and direct feedback from customers, Parker said it has designed every detail of the new clearcurrent® ASSURE filters to ensure they support predictable, reliable and optimised gas turbine performance.
“The efficiency we see from today’s advanced gas turbines, such as the H-class, is far superior to that of previous machines,” said Tim Nicholas, power generation market manager at Parker’s Gas Turbine Filtration Division. “The precise engineering involved to achieve these output levels requires a conditioned, consistent and reliable air flow through the inlet house, and our new line of filters helps to protect turbine health and performance.”
Advanced filtration innovation
Filtration systems for gas turbines require consistent innovation to keep pace with ongoing improvements to turbine design and performance. Advanced classes of turbines have recently broken the 60-per-cent net efficiency barrier in combined cycle mode. By leveraging technologies such as 3D printing and advanced analytics, such increased levels of efficiency are becoming increasingly common, and it is expected that further improvements will soon follow.
Parker’s new clearcurrent® ASSURE filters feature durable hydrophobic and oleophobic properties, which remove problematic contaminants carried through to the turbine in liquid forms. Their unique design provides effective filtration across a range of models including high-performance self-cleaning units. Construction practices and materials are selected for extended service life to enable longer maintenance intervals and reduced lifetime cost while sustaining performance.
Setting a new benchmark in machine protection
“The lower efficiency of legacy turbines means that particles adhering to the blades have less impact on performance. However, to maintain the efficiency of the advanced performance turbines entering the market today, internal components need better protection from sticky particles in the inlet airflow which can impact aerodynamic and thermal performance,” Mr Nicholas advised. “Our clearcurrent ASSURE filters are designed with housing materials and filtration media that is precision-engineered to set a new benchmark in protecting these incredible machines.”
The measured and consistent performance of the clearcurrent® ASSURE filters through all filtration stages equates to predictable differential pressure (DP). This is essential to avoid sudden pressure spikes that lead to unplanned turbine outage or damage to the system. They are designed to an exact fit in the inlet house to prevent them being bypassed, significantly reducing the risk of accelerated degradation of turbine components and helping to optimize maintenance over the life of the system.
