At Suburban, we use a pressurized pump system on our tankers that force the "LIQUID CALCIUM CHLORIDE" through a spreader bar with calibrated nozzles that spray a perfect pattern on the road surface.  Please note that it does not drip or pour out of the truck, the chemical is applied only where we want it applied.

Spreader bars are blown clean before crossing paved roads and our pumps are easily calibrated to operate in an efficient manner to accommodate road conditions (hard or fresh graded) or customer's specifications.
