Double-sided Cross-flow Open Cooling Tower
This cross-flow open cooling tower with dual-side air intake is an ideal choice for industrial and central air‑conditioning circulating water cooling systems. It utilizes cross‑flow heat exchange technology, in which cooling water descends vertically through the fill media while air enters horizontally from both sides across the fill layers. The air and water streams flow perpendicular to each other, enabling efficient heat dissipation. Constructed from high‑quality metal sheets, the unit offers excellent structural rigidity, fire resistance, and weather resistance, effectively reducing operating and maintenance costs. It is widely used as a reliable cooling solution in chemical, power, food processing, and large‑scale commercial building HVAC systems. Specifications Heat rejection capacity: 349 – 2,035 kW Flow rate: 264 – 1,541 gpm / 60 – 350 m³/h Type: Cross-flow / Axial fan / Induced draft
How it works?
The double-inlet cross-flow open cooling tower relies on cross-contact heat exchange between water and air. Hot circulating water is evenly distributed from the top distribution basin over the fill media, forming thin film-like flow descending through the fill. Meanwhile, fans draw ambient air horizontally from both sides across the fill. With the air and water streams flowing perpendicular to each other, heat is removed through both sensible exchange (temperature difference) and latent exchange (evaporation), significantly reducing water temperature. The moist heated air passes through the drift eliminator at the top before being discharged, while the cooled water collects in the bottom basin for recirculation. An automatic make-up valve and a bleed-off port are provided to maintain stable water quality.
Structure & Characteristics
-
1 、Fan:
Equipped with heavy-duty axial fans specifically designed for cooling tower applications. Blades are constructed of nylon or aluminum alloy, dynamically balanced for smooth operation, high airflow, and low noise levels.
-
2 、Water Distribution System:
Utilizes a pressure-type distribution method with anti-clogging ABS basket-type nozzles that ensure uniform spray coverage without dead zones. The distribution piping is rationally arranged for low water pressure requirements, excellent spray performance, and resistance to fouling.
-
3 、Fill:
Features high-efficiency PVC fill with a fluted sheet design that provides a large specific surface area and strong hydrophilicity, promoting thorough air-water heat exchange. The fill offers high flame retardancy, excellent temperature resistance, and an extended service life.
-
4 、Drift Eliminator:
Positioned above the fill section and before the air outlet, constructed with high-efficiency curved baffles or honeycomb structures to effectively capture entrained water droplets from the air stream. Drift loss is minimized to below 0.01%, significantly reducing water waste.
-
5 、Collection Basin:
Features a integrally molded bottom basin, constructed of the same material as the casing with ample capacity to ensure consistent water supply even during sudden flow fluctuations. The basin bottom includes a drain port and make-up water valve for convenient cleaning and maintenance.
-
6 、Casing:
Manufactured from high-quality ZAM-coated steel or stainless steel sheets, precision-formed for flat, tightly fitted panels. The surface is treated with a hot-dip galvanizing process, providing superior corrosion protection and an attractive appearance.
-
7 、Base Frame:
Serves as the foundation support for the entire tower, bearing the equipment weight and transferring it to the ground to ensure stable operation. Constructed from galvanized channel steel; stainless steel is available as an option for applications requiring additional corrosion protection in humid or chemically aggressive environments.
