Pneumatic Powder Loading

Powder handing solutions that deliver under pressure.

Rockwater provides state of the art powder loading in a closed loop system engineered to quickly load our fleet of pneumatic trailers for field delivery. FIBC bags containing guar powder can be safely loaded through a system of screens, conveyors, and dust collection. Dust is fed back onto the conveyor and into the trailer for nearly zero product loss, as well as reducing the risk of slippery conditions on location. Under optimum conditions a 1,350 cubic foot pneumatic trailer can be loaded in 45 to 60 minutes. Rockwater has several loading facilities in key basins across the U.S. They are supported by our team of Smith System certified drivers and in-house dispatch providing time critical support for our customers 24/7.
