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

• 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

Connection sizes available: 1/2″ to 1 1/2″

Finest fog of any direct pressure nozzle. Produces high percentage of droplets in the 25-400 micron range; ideal for dust suppression.

1/4″ connection.

Excellent choice for deluge applications where there is little distance between nozzle and material being protected. Marine applications include deluge, foam, and water wall systems where the nozzles are subject to extreme weather conditions and exposure to seawater.

Connection size available: 1/2″

Largest free passage in the original spiral nozzle invented by BETE and continuously improved!

Connection sizes available: 3/8″ to 4″
