HOLLOW CONE PATTERN

A hollow cone spray pattern consists of droplets concentrated onto the outer surface of a conical shape volume, with no droplets in the inside.
These nozzles are normally used for smoke washing or gas cooling applications in several industrial processes.

HOLLOW CONE (TURBULENCE NOZZLE)

These nozzles use a tangential injection of liquid into a whirling chamber to generate centrifugal forces which break up the liquid vein as soon as it leaves the orifice.
Precisely designed orifice profiles, making use of the Coanda effect, enable very large spray angles.

HOLLOW CONE (IMPACT NOZZLE)

A hollow cone can also be produce by having a liquid vein impact onto a purposely-designed surface. This then breaks the liquid into droplets and forms a hollow cone spray pattern.

This type of nozzle is suitable for applications in fire fighting systems.
