From landfills to chemical processing, this technology addresses complex challenges by leveraging existing low-cost energy sources. Featuring two models, F and R/S, with **specialized heat transfer technologies**, the AC series efficiently handles a wide range of wastewater types. Both models in the Evaled AC series are tailored to address specific industrial water treatment needs, ensuring optimal performance. The **AC F series** is engineered with forced circulation technology, this model excels in minimizing fouling and scaling issues. It is the perfect choice for operations aiming to achieve high concentration levels, especially when waste thermal energy and cold water are abundant on site. By leveraging these existing resources, model F offers an efficient solution for complex wastewater treatment needs. The **AC R/S series** is designed with natural circulation and equipped with a specialized heat exchanger featuring scraped heating surfaces. R/S shines in specific scenarios: It is particularly adept at reducing concentrate volume to a minimum, making it ideal for treating wastewater with high initial concentrations of dissolved or suspended substances. Additionally, R/S excels in processing pre-concentrated wastewater, offering a versatile solution for challenging treatment requirements. ![Evaled ACR12 evaporators aligned](/sites/g/files/dvc2476/files/styles/media/public/image/2025/04/Evaled-AC.jpg.webp?itok=zXCIOnmk) ### Key benefits of the Evaled AC series The Evaled AC series performs well in **energy and resource optimization**, featuring low electrical consumption (12-30 kilowatt hours per ton of distillate), waste heat utilization, and low operating temperatures (30-70°C / 86-158°F), 4-30 kilopascal (kPa). The system's **operational flexibility** allows for handling various wastewater types in both continuous and batch modes, with customizable capacity from 3,000 to 12,000 liters daily. It produces **high-quality recyclable distillate and concentrated waste** (more than 75% total solids), all managed through programmable logic controller (PLC-controlled) automated operation requiring minimal supervision. This versatile system is ideal for industries seeking to optimize their water treatment processes efficiently and sustainably, allowing them to achieve the zero liquid discharge (ZLD) configuration. Discover how the Evaled AC series can be customized to meet your specific needs, aligning with both your operational requirements and sustainability goals.
