The dry cooler uses ambient air as the cooling medium to cool or condense high-temperature process fluids flowing through finned tube bundles. Available in V-shaped, vertical, or horizontal configurations, the unit can be adapted to different installation and heat-transfer requirements. An optional humidification system can pre-cool the incoming air to near its wet-bulb temperature, increasing heat-transfer capacity and enabling a lower process-fluid outlet temperature. Dry coolers are used across chemical processing, petroleum, power generation, metallurgy, building materials, polysilicon, PVC, cement production, waste-to-energy, and data center applications, and are particularly suitable for water-scarce regions.
