  • Flat spray pneumatic nozzle producing a large volume of semi-fine atomization with a mean droplet diameter of 50 μm or more (*3).
  • Liquid pressure type under the liquid pressures of 0.07–0.7 MPa (ca. 0.7 bar – 7 bar).
  • Large turn-down ratio with minimal variation in spray angle.
  • Uniform distribution suitable for multiple-nozzle arrangements.
  • Large free passage diameter minimizes clogging.
  • Spray angle of 55°, 70°, 95°, or 110°.

*1) Measured at compressed air pressure of 0.3 MPa (ca. 3 bar) and liquid pressure of 0.7 MPa (ca. 7 bar).
*2) Free passage diameter of nozzle orifice.
*3) Measured by Fraunhofer diffraction method.


  • Cooling: Gas, steel plates, steel pieces, moldings, etc.

[Steelmaking industry]

  • Steel making process: Cooling continuous casted steel (bloom and slab)
  • Rolling mill process: Cooling roll in heat treatment
