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

A diagram that indicates the variation of capacity and spray angle for different pressures.

Spray angle

Depending upon the nozzle design, variations of feed pressure may have a great influence on the spray angle value. This test is made with a measurement optical system.

Spray coverage

Spray coverage depends on the amplitude of the spray angle, on the distance between the nozzle orifice and the target to be covered, and on the pressure. The actual values can differ a lot from the theoretical values.

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.

Wetting and washing radius for tank washing heads

For our tank washing heads (fixed, reaction drive, high impact) we can determine both the wetting radius (the radius where the equipment can wet the entire tank inner surface) and the washing radius, which depend on the product to be eliminated, the cleaning fluid, the operating pressure and temperature.

Others, on request

Depending on the request of the customer, we are available to settle any kind of test, in order to provide all the information regarding our products.
