HBN Mini hollow-cone spray nozzle

Mini nozzles are spiral or axial hollow cone nozzles with integrated disc filters operated by fluid pressure. Special grooves in a swirl body sets the fluid in rotation and emerges at the nozzle bore as a simple hollow-cone vaporisation. Shortly after leaving the nozzle, the stream dissolves into tiny droplets (<100 µm) and creates the typical fine mist which then impacts upon a surface in the shape of a ring. This specific turbulence results in a drop spectrum with an increased degree of efficiency.

  Application range

These are requirements for various applications, e.g. for process and object cooling, for dust trapping (coal power plants), humidification of goods (foods industry), for air humidification (air conditioning) and for especially for oil and fuel vaporisation.

  Spray pattern and water distribution

In practice, the theoretical cone diameter will deviate somewhat due to external influences.

Therefore, borderline cases should be individually discussed in terms of practical application.

Calculate it for yourself

Simply determine by yourself, which nozzle fits to your needs. There are two ways:

Water flow rate (Q = K√p)
Q = l/min


Nozzle constant (K = Q/√p)
