The Science of Misting

By pressurizing water up to 1000 psi and forcing it through a specially designed nozzle, billions of tiny water droplets can be created. Each droplet is smaller than the size of a grain of salt and can measure as small as 5 microns in diameter. The droplets are so light they actually suspend themselves in the air. This process known as a mist system allows for a reduction in the ambient temperature of up to 30 degrees fahrenheit making these systems ideal for outdoor cooling.

If the droplets are enclosed in an area such as a greenhouse, humidity levels up to 100% are achievable allowing fog systems to provide precise and reliable humidity control. Because the droplets are so small, they also have the ability to remove small particles from the air making fog systems a very effective method of dust and odor control.

    Whenever Fogco begins the process of designing a misting system for a customer, we have three basic pump design options. These options include a direct drive (dd) pump; a pulley drive (pd) pump; or a variable frequency drive (vfd) pump also known as an inverter drive pump. Each option has its own set of pros [...]

    Misting Nozzles Explained

      Why so many misting nozzles? Misting nozzles come in a variety of shapes and sizes. It is often asked,’Why so many and what are the differences?’. The purpose of this blog is to answer these questions and define the performance capabilities of the impeller misting nozzles offered by Fogco. Impingement versus Impellar There are [...]
