VACOMASS® flexcontrol

Field housing with modular electronic modules for control of air supply and air distribution

The VACOMASS® flexcontrol panel is an open, PLC-based control system featuring a modular design and intuitive operation. It is easily adaptable to plant-specific requirements and avoids the complexity of closed “black box” solutions by using standardized building blocks and proven control algorithms. Each control loop is clearly structured and operates independently, ensuring transparent, reliable, and stable aeration control with seamless integration into existing automation systems.

Key features

• Modular system to optimize nitrogen elimination while reducing energy consumption in sewage treatment plants
• Can be used regardless of the size of the sewage treatment plant
• Possible to measure exact air flow in the individual basins (zones)
• Unique, high-precision control valves, especially developed for aeration air, with demonstrably much lower pressure loss in control operation than all other valves available on the market
• Control modules developed specially for the application in the flexcontrol field housing, which contain all control strategies for nitrogen elimination according to DWA-A 268 and maintenance of the aerators according to DWA-M 229
• The flex algorithm improves process stability and reduces operating costs for aeration, avoids plant malfunctions, ensures compliance with the limit values in the effluent and enables economical operation of the treatment plant
• proven concept with many international references on sewage treatment plants of different sizes
