TF Series Full Cone Spiral Nozzle, 1/4 NPT
BETE is the original inventor of the spiral, also known as a pigtail, corkscrew, or helix nozzle. Its durable, one-piece design with no internal parts delivers clog-resistant performance and high energy efficiency. When compared to whirl-type nozzles of the same flow rate, pressure drop and angle, TF spirals produce considerably smaller droplet sizes for fine atomization. These nozzles are all 1/4 NPT.
Applications
Gas Cooling
Gas Scrubbing
Chemical Injection
Dust Control
Spray Pond Cooling
Evaporative Disposal
Humidification
Fire Protection
Advantages
Original spiral nozzle was invented by BETE
One-piece design with no internal parts
Durable & clog-resistant
Produces fine atomization
Energy efficient with high velocity discharge
Available in a wide range of flow rates and angles
TF Series Full Cone Spiral Nozzle Materials
Brass
The spiral nozzle pattern is created by fluid shearing along the spiral's turns, creating multiple concentric hollow cones. This design produces two to three bands of coarser droplets, each surrounded by wider bands of finer droplets, resulting in full coverage.
