CDA technology: controlled droplet application on Micron sprayers

The secret of an efficient spraying lies in an even and specific droplet distribution.

What is it about?

Most conventional spraying machines employ a hydraulic nozzle which involves breaking up spray liquid by squirting it under pressure through a hole.

This application method is rather inefficient as it breaks up the spray liquid very unevenly and produces a very wide range of droplet sizes.

Very large and very small spray droplets are both wasteful - the large ones end up on the ground whereas the small ones drift wasting much of the spray and contaminating the environment.
This inefficiency means that hydraulic nozzle sprayers have to use much more spray liquid than is actually necessary to do the job.

To fetch, carry and spray this extra liquid costs time, effort and money for both the small farmer in the developing world carrying out most jobs manually or the large mechanised western farmer.

Real case comparison

Pioneered by Micron Group, Controlled Droplet Application (CDA) produces only the optimum sizes of spray droplet for the particular application. This is achieved by specifically designed spinning disc rotary atomisers which break up the spray liquid very evenly, resulting in a narrow range of spray droplet sizes.
