Industrial wastewater low-temperature evaporators are specialized environmental protection and energy-saving equipment designed for the treatment of industrial wastewater (e.g., from chemical, electroplating, electronics, pharmaceutical, and printing industries). Unlike traditional high-temperature evaporators that operate above 100°C, these devices utilize low-temperature evaporation technology (30°C) to separate water from contaminants in wastewater, achieving wastewater concentration, volume reduction, or even zero liquid discharge (ZLD).
