Power Generation

Graver Technologies offers innovative solutions for the power generation industry, including high-performance filtration systems. Our Power Generation Filters, crafted from laminated stainless steel mesh, are engineered with high void volume and controlled porosity, ensuring efficient filtration and longevity. These filters enhance system performance by providing under drains equipped with wedge wire technology. This feature supports high differential pressure and ensures a low net positive suction head for upstream pumps, optimizing operational efficiency. Additionally, the design accelerates installation, offering a reliable barrier to maintain the integrity of your ion exchange bedded resin, contributing to improved system reliability and reduced downtime.
