The KWN/H Series is specifically designed for heavily contaminated fluids, including wastewater, sludge, slurry, process effluent, and high-fouling industrial liquids. It is ideal for applications where conventional heat exchangers experience frequent blockage or cleaning challenges.

The unit utilizes straight-tube heat exchanger technology combined with mechanically cleanable header boxes. Maintenance personnel can directly access individual tubes for physical cleaning, enabling efficient removal of deposits that cannot be eliminated through chemical cleaning alone.

Straight tubes provide direct access for mechanical cleaning tools and reduce the risk of solids accumulation inside the heat exchanger. This design improves maintainability, extends service life, and enhances reliability in wastewater and slurry cooling applications.

Depending on fluid characteristics and operating conditions, the KWN/H Series can be manufactured using 304 stainless steel, 316L stainless steel, Duplex 2205 stainless steel, or titanium. Material selection is optimized according to corrosion resistance requirements and project specifications.

The KWN/H Series is widely used in wastewater treatment plants, mining operations, metallurgy, paper mills, chemical processing facilities, and other industrial applications involving highly contaminated or fouling-prone fluids.
