BETE MicroWhirl (MW) Misting and Fogging Nozzles

Patented Hydraulic Atomizing Nozzles with Drip-Free Operation

By using BETE spray nozzles with very small orifices, a fine droplet size can be attained even at relatively low pressures. BETE misting nozzles utilize two main technologies; the first is the use of an impingement pin to achieve atomization, the second uses a very small whirl to achieve atomization. When used at higher pressures, direct pressure misting nozzles produce a droplet size that rivals air atomizing nozzles.  The BETE MicroWhirl Head (MWH) spray nozzle is a standard, stock manifold for up to (7) individual MicroWhirl nozzles. These high pressure nozzles produce very low flow, and extremely fine misting protection.

Design Features of BETE MicroWhirl Head MW Spray Nozzles

  • Finest atomization of any direct pressure multi-nozzle
  • Rugged pin less design
  • Narrow drop spectrum
  • Minimum operating pressure 100 psi (70 bar)
  • Other manifolds and flow rates available
  • Patent pending
  • 70-micron polypropylene filter
  • Safety wire hole available
  • Optional 200 mesh filter 316SS

How Spray Pattern is Achieved

  • Misting nozzles create a very fine mist or fog. Droplets are typically small enough that buoyancy is significant compared to gravity, allowing drops to appear to float. In the absence of upward airflow, particles are simply falling very slowly.
  • Mist at low pressure.
  • Fog at high pressure.
