Will It Spray?

One of the common questions we receive with regards to our Atomizing Spray Nozzles, is whether they will spray a specific liquid.  Most of the time this is a simple answer, found by referencing the viscosity of the liquid and the viscosity range of the specific atomizing nozzle in question.  But, sometimes the viscosity of a fluid isn’t readily available and the best path forward is testing of the specific fluid or application.

Such was the case with the videos above and below.  This application was to spray a specific mixture comprised of catnip biomass onto materials as they pass along a conveyor.  There was no specific flow rate required, we simply needed to spray a specific width at a specific distance away from the product.

The video above shows the desired spray pattern from the nozzles, something with a wide angle and flatpattern, and the video below shows the most suitable solution we found in testing at EXAIR.

The suitable nozzle in this application was our model AD2010SS, an internal mix nozzle with deflected flat fan spraying pattern and a patented technology to prevent liquid flow after compressed air to the nozzle is turned off.  This nozzle provided the right solution for this application, and shipped from stock on the same day we received the order.

Fast forward a few weeks and this same application found benefit from an Electronic Flow Controller (EFC) model 9057.  The EFC allows for sensor-based control of compressed air flow, and thereby control of liquid flow to the AD2010SS nozzles.  This prevents operation of the nozzles when there is no need to spray the liquid.

The discussion, testing, and implementation of this solution are an excellent example of the engineering support available behind EXAIR products.  We really do help our customers find solutions, and if there is an unknown in an application we’re willing to find the answers together.
