Agitator / Mixer Tank
An Agitator / Mixer Tank is an industrial piece of equipment. Agitator / Mixer Tank are combining to a vessel (tank) with a mechanical device (agitator) to mix, blend, homogenize, suspend liquids, gases, and powders. It uses a motor-driven system to rotate the shaft with impellers (propellers, turbines, or paddles) to create the fluid motion and enhance the chemical reactions and temperature to control industries.
Agitator / Mixer Tanks are widely used in industries such as chemicals, pharmaceuticals, treatment, and petrochemicals. To ensure the uniform consistency and efficient processing of the materials, agitator / Mixer Tanks are manufactured in various materials like HDPE, PPH, FRP, and PVDF.
