Fire Protection Approved
This BETE high-efficiency spiral was designed specifically with critical fire and explosion suppression applications in mind. These nozzles feature superior performance unequalled by traditional whirl nozzles.

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

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
