Unimin will be exhibiting FILTERSIL® Well Gravels and Filtration Sands for Water Production and GRANUSIL® Mineral Fillers for Optimal Geothermal Performance. Produced from high purity industrial quartz, FILTERSIL Well Gravels and Filtration Sands are extensively processed and seized to produce durable down hole media with uniformity coefficients that reduce pumping costs, increase hydraulic conductivity and extend well service life. GRANUSIL Mineral Filler is a highly conductive silica sand. Engineered to optimize particle packing density while minimizing voids, GRANUSIL enhances the heat transfer efficiency of thermal grout systems.
