Abstract: Systems and methods of dispensing a hot melt adhesive material that can be heated from a lower temperature flowable non-molten liquid state to a higher temperature molten liquid state, the systems and methods comprise: pumping with a pump the hot melt adhesive material in the lower temperature flowable non-molten liquid state into a supply conduit; passing the hot melt adhesive material through a heated thermal break in the supply conduit that allows free flowing movement of transitional non-molten and molten state material; heating the hot melt adhesive material in a heat exchanger connected to the heated thermal break to the higher temperature molten liquid state; and dispensing the hot melt adhesive material in the higher temperature molten liquid state from a dispenser in fluid communication with the heat exchanger.
