Spillback
Spillback nozzles are special single-fluid nozzles that atomize liquids into a fine hollow cone spray. In comparison to traditional single-fluid nozzles, spillback nozzles ensure consistent droplet size over the entire controlled flow range without changing pump pressure.
The Spillback nozzles can lower operating cost because they do not require compressed air. Spillback nozzles are used for gas cooling and conditioning processes commonly found in chemical processing, petrochemical, pollution control, and cement industry.

Choose the right spray nozzle for an optimised spray process
Each type of nozzle has a specific flow rate, spray pattern and droplet size. To optimise the spray process, it is important to understand how different parameters affect the choice of spray nozzle and type of solution.
The Knowledge base contains information about spray pattern, droplet size, flow rate/pressure, spray coverage, materials, etc. The 'Materials' section of the Knowledge base lists the most commonly requested materials and maximum temperature of the material.
