Our tanker trailers receive a Kosher wash at our on-site, 5 bay wash facility before they transport goods. We wash only tanker trailers containing food-grade products that have been transported by Keith Hall Transport. To clean our trailers, a hose line is hooked up to the internal spray ball system that is inside of the trailer. When we clean a trailer not equipped with spray balls, we use a gamma jet spinner. To keep our environment clean, our wash bay is also equipped with a waste water treatment system.
