Every nozzle is tested, then Delavan goes one step further and cleans the test oil from the nozzle to avoid plugging.
Solid Cone Type "B" nozzles produce a spray that distributes droplets fairly uniformly throughout the complete pattern. the spray pattern becomes progressively more hollow at higher flow rates, particularly above 8.00 GPH. Provides smooth ignition and efficient combustion, particularly in larger burners.
