Lab test
PNR internal laboratory is equipped with very sophisticated instruments that allow us to perform different test, on request of the client:
Air – water working curve
Spray angle
Spray coverage
Spray distribution
This test can give a precise information about how evenly the drops of the spray are distributed onto the area covered by the spray. The water distribution along the spray coverage is determined by means of an instrument called “Patternator”.
Droplets spectrum
PNR droplets size test reports are performed by means of a Laser Interpherometer (PDPA – Phase Doppler Particle Analyzer), where two laser beams cross in a given point of the spray and define a test probe area. Droplets flying through the probe area cause a light scatter which is picked up by the instrument receiver and processed through a computer, in order to obtain relevant information about the spray characteristics, such as Sauter Mean Diameter, distribution curve of droplets diameter (micron), distribution curve of droplets velocities (mps).
Impact force and spray distribution for air blowers
Test made on spray nozzle can be performed also on air blowing nozzles (model UEA and UEB).
Phonometric test
Both ultrasonic atomizers and air blowers produce noise, therefore we can produce a diagram of the noise level for different working pressures and distance.
Impact force for descaling nozzle
Our own made descaling bench test allows us to give the client precise information on descaling nozzle, such as impact pressure (maximum and average), area of impact (three dimensional), overlapping coverage.
