Lechler developed the new SMDmax™ full cone spray nozzle specifically for entrainment-sensitive spray applications. This nozzle produces significantly coarser droplets than traditional spray nozzles used in entrainment sensitive applications. Moreover, the state of the art Lechler SMDmax™ technology is also entirely machined, which helps achieve a high-tolerance surface finish inside and out, producing consistent performance every single time.
Traditional free passage style nozzles designs allow for maximum water droplet distribution for the application. However, this design can cause the water droplets to pull ambient air along the nozzle when spraying out, increasing the velocity of the air and causing a lower pressure around the nozzle tip in a process called entrainment.
For certain water nozzle applications, entraining more air is ideal when wanting to create a powerful jet of water. Yet for free flowing nozzles, this increase of entrainment leads to varying water droplet sizes and unpredictable spray distribution. The SMDmax nozzle from Lechler lessens the entrainment and improves the spray performance for the application.
