Üçsan Counterflow Open Circuit Cooling Towers operate on the counterflow principle, where water and air move in opposite directions, providing high heat transfer efficiency. Thanks to their compact design, ability to achieve low approach temperatures, and durable long-life construction, they provide a reliable and economical cooling solution for industrial process applications. Each cooling tower is specifically engineered according to operating conditions and delivers high performance, low energy consumption, and reliable operation for many years.

Key Advantages

  • High heat transfer efficiency through counterflow operation
  • Operation at low wet-bulb approach temperatures
  • Reduced space requirement thanks to compact design
  • Low energy consumption
  • Quiet operation
  • Easy maintenance and service access
  • Modular design
  • Long service life

Operating Capacity

100,000 kcal/h – 3,600,000 kcal/h (116 kW – 4,186 kW). Thanks to its wide capacity range, it provides highly efficient solutions suitable for different flow rates, temperatures, and process requirements.

Installation Advantage

The cooling towers are fully assembled in the factory and delivered ready for transportation. Since no on-site assembly is required, installation time is reduced, labor costs are minimized, and fast commissioning is ensured.

Casing Material Options

The cooling towers can be manufactured with different material options according to operating conditions and corrosion levels.

  • 275 g/m² galvanized coated steel sheet
  • 304 grade stainless steel
  • 316 grade stainless steel
