Hollow cone spray nozzles are an extremely simple design that produces a high quality, small droplet size spay pattern primarily through centrifugal force. Using the design enables standard type hollow cone nozzles to produce a soft circular spray of relatively fine droplets, while having a free passage size (good clog resistance) considerably larger than flat fan or full cone nozzles of similar flow rates. Free passage size is important in applications involving solids particulate in the liquid being sprayed, such as in a recirculating water cooling pond application. Fine droplets are important in gas and other product cooling applications, because finer droplets mean more water surface area in contact with the gas or other product being cooled. Soft impact is important to minimize bounce-back and product damage in applications where a coating is being deposited onto a surface, or where delicate items such as soft fruit are being sprayed.
