Whirl spray nozzles give a conical hollow spray.

In the annular part, the flow distribution in the circumferential direction is uniform and there is no risk of clogging because there is no obstacle inside the nozzle. Used widely in steel work and chemical plant applications, including cooling of steel materials, ventury scrubber gas humidifying and cooling, gas absorption, return water cooling, dust protection, dust collection, defoaming, defrosting, washing, flue gas desulfurisation and chemical solution spraying. Caution: When durability is particularly required, a heavy type having a long life against cavitation is manufactured. Standard types should be used at a pressure of 3kg/cm2 or less if made of brass or bronze, and 5kg/cm2 or less if made of stainless steel.
