Abstract
A system for dispensing polyurethane foam from DOT-39 compliant tank, includes a compressor having an outlet through which air is supplied, and a booster coupled to the outlet of the compressor. The booster provides a supply of compressed air at a pressure of between about 160 and about 200 pounds per square inch. At least two bladderless tanks having an internal volume sized less than 1,526 cubic inches to comply with DOT-39 specifications each contain a quantity of a polyurethane foam component that is sufficient to fill at least 70 percent of the internal volume of the bladderless tanks. A first valve on the bladderless tanks connects to the high pressure outlet of the booster. A second valve is adjacent the bottom of each bladderless tank. A dispenser for dispensing the polyurethane foam component is connected to the second valve on each of the bladderless tanks.
