Hexacool® induced draft configuration
saves up to 15% fan power consumption.



About Hexacool®

Hexacool® is a standardised, modular air-cooled condenser (ACC) which is easy to build and robust in performance. This product is well-suited for small power plants that range from a few megawatts to 50 megawatts. ACCs directly condense the steam turbine exhaust flow and return condensate to the boiler without water loss.

Typical Hexacool® applications include

  • waste-to-energy plants
  • biomass power plants
  • geothermal power plants
  • small sized electrical power plants
  • industrial/process plants, where Hexacool® is a more cost effective
    solution than a traditional A-Frame ACC.

Features of

Hexacool®, a revolution in Air-Cooled Condensers.

Hexacool® is a standardized, modulair air-cooled condenser system that is low in cost, easy to erect and robust in performance. It is the most suited solution for small power and industrial applications where a standard A-Frame model is not the most cost-effective solution.

Hexacool® is a highly qualitative product and a cost-effective solution for your application. The design is compact and simplified thanks to the higher degree of prefabrication in the workshop. Hexacool® offers a reduced load on foundation.



Hexacool® has a low profile design, the total height is lower than an A-Frame design. This results in an easier integration in urban environments and easier construction in the field.


High performance

Hexacool® offers an outstanding performance during windy conditions. The induced draft concept reduces the risk of hot air re-circulation. This leads to a higher efficiency in all operating conditions.



Hexacool® is a trendsetter in the industry thanks to its environmentally friendly design. The units are designed for easier cleaning and maintenance.

A-frame Air-cooled condensers immediately condense the steam turbine exhaust flow and return condensate to the boiler without water loss. They are frequently used in electrical power plants and waste to energy plants of all sizes.
ModuleAir® is an innovative modular air-cooled condenser (ACC) that directly condenses steam turbine exhaust flow and return condensate to the boiler without any water loss. With construction savings of up to 25%, compared to a standard A-frame, construction time can be reduced by several months for large power plants.
W-Style ACC® is an innovative Induced Draft Air-Cooled Condenser (ACC) directly condensing the steam turbine exhaust flow. The condensate returns to the boiler without any water loss. With its unique “W” heat exchanger structure, the amount of steel and overall height of the ACC are dramatically reduced. This is useful for all power plant applications.
BoxAir ACC® is an innovative Induced Draft Air-Cooled Condenser (ACC), suitable for all power plants ranging from 1 to 30 MWe. This ACC type consists of standard boxes that are easy to assemble and that offer a short delivery schedule and high reliability level. BoxAir ACC® is used in waste incineration plants, biomass, solar and geothermal power plants and is suited as a capacity increase of an existing power plant.
An Indirect Dry Condensing system connects an Indirect Dry Cooling tower (IDCT) with a steam surface or jet condenser. Its tall concrete or steel shell eliminates hot air recirculation. Indirect Dry Cooling solutions offer a reduced maintenance and are suited for large capacity condensing units.
Air-Cooled Heat Exchangers (ACHE) are custom designed heavy-duty fin tube heat exchangers. They allow the direct cooling by air of various process mediums. ACHEs are used in applications in many industries, such as power, chemical, ORC plant, Oil & Gas, steel and several other industries.
