CHENENG Wastewater Bar Screens

Wastewater Bar Screens

At CHENENG Water, we’ve revolutionized rotary screen technology with our optional intelligent program. This advanced system features a specially designed frequency converter for the motor, dramatically reducing energy consumption. Our solution embodies simplicity and efficiency – it’s a true plug-and-play unit that requires no configuration or parameterization. The integrated data log leverages historical values to calculate the optimal startup speed for any application, effectively preventing overflow. Furthermore, the frequency converter automatically adjusts the screen speed, ensuring peak performance under all conditions. With CHENENG Water’s intelligent rotary screen, you’re not just investing in equipment; you’re embracing the future of water treatment technology where innovation, ease of use, and efficiency converge.
