Power Generation

Graver Technologies provides Power Generation Filters in the form of laminated stainless steel mesh with high void volume and controlled porosity. Graver Technologies filters also equip under drains with a wedge wire that gives high differential pressure and a low net positive head suction for upstream pumps. This saves time during installation and adds a controlled barrier to keep your ion exchange bedded resin in place.
