Steam nozzles are great for removing moisture as well as oil from steel surfaces. The inlet narrows to form a throat, which is followed by an enlarging form so that atmospheric pressure is reached by adiabatic expansion, producing a flat jet pattern. To decide if you need the blank or flat nozzle you need to analyze the job it’s for.
Hollow cone distributes the atomized oil particles evenly toward the outside of the spray cone. These nozzles are particularly well suited for low firing rates and burners with a hollow air pattern. Normally used in wider spray angles. All Hago nozzles are 100% tested on oil for accuracy of flow rate, spray angle, concentricity, and spray quality.
