Introduction to Corona Generators
Corona generators are essential devices in various industrial and scientific applications. A corona discharge is an electrical discharge that occurs when a high voltage is applied to a conductor, causing ionization of the surrounding gas. Corona generators are designed to produce and control this corona discharge. They find wide - spread use in fields such as air purification, surface treatment, electrostatic precipitation, and ozone generation.
In air purification, corona generators can ionize air molecules, which helps in attracting and removing dust, pollen, and other particulate matter. In surface treatment, they are used to modify the surface properties of materials, improving adhesion and wettability. Electrostatic precipitation utilizes corona generators to charge particles in a gas stream, enabling their collection on electrodes. Ozone generation is another important application, where the corona discharge breaks down oxygen molecules to form ozone, which has strong oxidizing properties and is used for disinfection and water treatment.
Now, let's take a look at the top 10 corona generators suppliers in the world in 2026.
