This pre-wet unit is designed to slide beside a salt applicator in the bed of a smaller truck. This unit will apply a small amount of product to the salt to help it react quicker with the ice and snow. The tank is a Norwesco PCO tank and comes in multiple sizes to fit your particular needs. This unit comes with a John Blue 12 volt electric pump and a rheostat in the cab to adjust the flow of the product. It comes with a quick fill to make refilling the tank a quick process.
