The first step when choosing the right spray nozzle is to define the function and application of the spray process, such as cooling a gas, washing a tank or flushing a conveyor belt. Type of spray nozzle, thus also spray pattern and droplet size, are important to consider in order to optimise the spray process.

Droplet size is often critical in optimising a spray process. Many processes, such as gas cooling and gas scrubbing, depend on exposing the maximum total liquid surface area. The liquid then needs to be distributed in a large number of small droplets to create as much total surface area as possible. Other spray processes ...

The position of the nozzle over the target (D) and the area to be covered by the spray (B) are important to know in order to choose the right spray angle (A). The spray angle is measured near the nozzle orifice and the droplets are immediately affected by external forces such as gravity, air and gas flow.

Desired volume flow depends on the specific spray process. Most spray processes have general rules of thumb for flow ranges, but in many cases on-site testing is needed to achieve the right results.

A liquid's specific gravity, viscosity and the presence of particles affect the spray characteristics of the nozzle.

Sometimes the spray is affected by external forces such as process gas flows, air flows or wind.

Listed below are a number of factors that should be considered when selecting materials for a specific nozzle. An incorrect choice of material is likely to affect the performance and life of the nozzle. We are happy to help and advise on which material is most suitable in your ...

There are many factors to consider when selecting a nozzle for a specific spray process. An optimised spray process can make a big difference, contributing to: improved product and process quality increased production and reduced time for unplanned stops reduced maintenance costs lower operating costs by reducing the use of ...
