Bete N Superior Performance Characteristics:
- Sprays composed on droplets 30% to 50% smaller than conventional designs at equivalent pressures
- Extraordinarily large surface area of spray enhances evaporation and cooling
- Rugged, compact design
- Multiple concentric cone spray, unique to spiral pattern, maximizes contact
Bete N Superior Fire/Loss Prevention Applications:
- Gas wellhead protection
- Safeguarding ship-borne cargo
- Storage tank protection
- Secondary explosion protection in explosive, dusty environments
- Mitigation of HF and other toxic gas releases
Also available in nickel aluminum bronze and titanium, plus other materials on request.
Spray Angle Visual: 90° and 120°
How Spray Pattern is Achieved
- The spray pattern of the spiral nozzle is formed by the fluid shearing along with the turns of the spiral, which produce multiple concentric cones. These cones form 2 to 3 bands of relatively coarse droplets, surrounded by wider bands of relatively fine droplets.
- The large surface area of spray improves evaporation and cooling.
