Product Description

Overview of Large Industrial Cooling Tower

Large Industrial Cooling Tower by Mach Cooling    Mach Cooling’s large industrial cooling towers, part of the AD-NG series, are high-capacity counterflow cooling solutions designed for industrial applications. With a lifespan of 15-20 years with proper maintenance, these towers use corrosion-resistant FRP frameworks and advanced heat exchange technology to ensure efficient and safe equipment operation. Ideal for power, chemical, semiconductor, and data center industries, they feature intelligent control, low noise, and energy-efficient designs. Compare with our square cross-flow cooling towers for alternative configurations.

Operating Principle of Large Industrial Cooling Tower


The large industrial cooling tower operates using a counterflow mechanism for efficient heat exchange:

  1. Hot water is sprayed from the top onto the fill layer, forming a downward-flowing water film.

  2. Air enters from the bottom and flows upward through the fill, driven by fans, in a counterflow direction.

  3. Water evaporates, absorbing heat, while sensible heat transfer cools the remaining water, collected in the bottom sump for recirculation.
