Spiral nozzles work on the impact principle by deflection of a water stream onto a spiral surface which generates a continuous spiraling liquid curtain. The spray droplets do not have the same even distribution that is produced by other types of full cone nozzles, however they possess other features such as:-
1. the spray angle is maintained even at very low pressures and when spraying high viscosity liquids
2. because they don’t have a vane in them they are virtually clog free
3. they produce much smaller droplets than standard full cone nozzles
4. they are available in the widest range of materials of any nozzle type
Typical Applications – fire fighting, gas and smoke scrubbing, gas cooling, dust suppression & chemical processors.
