Sizing Applications

The intricate process of selecting multi-curved mixers is analogous to that of other mixers, with the method of installation being the only distinctive element. Essential parameters such as the pool's type, its volume, liquid depth, medium concentration, temperature, and pH levels are pivotal in guiding the selection process.
The selection of curved mixers is greatly influenced by determining each device's effective service area. In rectangular pools, it is crucial that the length-to-width ratio does not surpass twice the width. This allows the pool to be segmented into equal work units, which helps in determining the precise number of mixers needed for optimal performance.
For pools beyond 5 meters in depth or those with concentrations above the specified range, it becomes essential to consider enhancing the power or operational speed of the mixer. This ensures efficient mixing in scenarios involving large capacity and high concentration media.
Under typical operating conditions, a dry installation is recommended. However, in environments with noise or visual limitations, a submersible installation is more appropriate. Our company stands ready to assist users in selecting the most suitable option for unique environments.
