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
