BETE is the original inventor of the spiral, also known as a pigtail, corkscrew, or helix nozzle. Its durable, one-piece design with no internal parts delivers clog-resistant performance and high energy efficiency. When compared to whirl-type nozzles of the same flow rate, pressure drop and angle, TF spirals produce considerably smaller droplet sizes for fine atomization. These nozzles are all 3/4 NPT.
The spiral nozzle pattern is created by fluid shearing along the spiral's turns, creating multiple concentric hollow cones. This design produces two to three bands of coarser droplets, each surrounded by wider bands of finer droplets, resulting in full coverage.
