Misting impingement nozzles for odour control 

With this design of nozzle the fluid is ejected from the nozzle orifice and impacts upon a pin in the direct path of the water flow.  This breaks up and disrupts the flow into a fine spray.  This method of atomisation is very energy efficient meaning that very fine atomisation can be achieved at lower fluid pressures when compared to small orifice nozzles.  As a consequence, lower flow rates can be achieved whilst maintaining a very fine spray.

The limitations of these nozzles is range.  Available spray angles are limited and the spray produced has little momentum meaning the reach of any individual nozzle is small.  But they are none the less an excellent choice for many smaller scale odour control systems.

SNP offer two ranges of misting impingement nozzle.  The standard P range and a low flow rate PJ range which might be suitable for smaller applications.
