Misting nozzle 6011546 TF

humidityspraycooling

Overview
BETE is the original inventor of the spiral (also called pigtail, corkscrew or helix) nozzle. Its one-piece, no-internal-parts construction delivers clog-resistant operation and high energy efficiency. Compared with whirl-type nozzles of similar flow, pressure drop and angle, TF spiral nozzles produce considerably smaller droplets for finer atomization. All models referenced here use a 3/8 NPT inlet.

Applications

• Gas cooling
• Gas scrubbing
• Chemical injection
• Dust control
• Spray pond cooling
• Evaporative disposal
• Humidification
• Fire protection

Advantages

• Original spiral design by BETE
• One-piece construction with no internal parts for reduced clogging
• Durable, clog-resistant performance
• Produces fine atomization (smaller droplet sizes than comparable whirl-type nozzles)
• Energy-efficient, high-velocity discharge
• Wide range of flow rates and spray angles available

Materials

• Brass

How Full Cone Spirals Work
The spiral pattern is formed by fluid shearing along the spiral turns, creating multiple concentric hollow cones. This generates two to three bands of coarser droplets surrounded by wider bands of finer droplets, yielding full-cone coverage.
