THW

WIDE-ANGLE TANGENTIAL HOLLOW CONE SPRAY NOZZLE
Detail of the Hollow Cone Spray Pattern Icon

DESIGN FEATURES

Large free passage

Clog-resistant

No internal parts

Exceptionally uniform spray density

A very wide band of spray

Droplet size 20% - 50% smaller than competitive hollow cone nozzles

Inlet and outlet are in-line

Silicon Carbide is available upon request - design review required before quote/order acceptance as restrictions may apply

Note: spray angles are for cast alloy nozzles only, not SNBSC


HOW SPRAY PATTERN IS ACHIEVED

Tangential hollow cone nozzles utilize a supply of liquid perpendicular to the direction of spray. Flow enters a swirl chamber without the use of internal components - allowing for maximum clog resistance.

THW design produces a wide spray angle in comparison to traditional tangential hollow cone spray nozzles.
