When a solid is heated above its melting point, it melts and becomes liquid. By spraying this, it is turned into many fine particles. By applying cold air to these particles and solidifying them, spherical products are obtained. By selecting the spray conditions, the product size can be set in the range of a few microns to several thousand microns. Additionally, by mixing another substance that serves as a core into the melted material and performing a similar process, microencapsulation can also be achieved. ● For more details, please contact us or download and view the catalog.

The key point in dioxin countermeasures is to instantaneously cool high-temperature exhaust gases to below 200°C. It is required that the nozzle can "allow for the complete evaporation of water droplets in the cooling tower" and "create fine droplets of less than 100 microns." This is only possible with a high gas-to-liquid ratio two-phase nozzle. The new energy-efficient, high-performance pressurized two-phase nozzle has made the impossible possible. ● For more details, please contact us or download and view the catalog.
