About ModuleAir®

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, as it does with the traditional ACC.
ModuleAir® consists of factory pre-assembled structural components and modular heat exchangers that are integrated within steam and condensate manifolds. This leads to a huge reduction in construction costs, compared to a conventional A-frame ACC design.

Features of

ModuleAir® is a modular version of the conventional A-frame SRC® Air-Cooled Condenser design and features factory assembled structural components, duct and modular heat exchanger bundles.

With construction savings of up to 25%, construction time can be reduced by several months for large power plants. ModuleAir® can also increase power production at low ambient air temperatures.

Cost efficient

The ModuleAir® construction saves up to 25% in time (compared to a standard A-frame design). Thanks to the factory pre-assembled components, the assembly of steel parts on site is reduced by up to 50%.



The innovative technology of the ModuleAir® results in lower steam velocity in the finned tubes which leads to a lower risk of flow accelerated corrosion.



The combination of a reduced structural steel weight and a smaller number of foundations in the ModuleAir®, leads to a smaller ecological footprint.


High quality

ModuleAir® Air-Cooled Condensers are extremely resistant to corrosion and to freezing. This product guarantees a long-term mechanical and thermal integrity.

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.
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.
Hexacool® is a standardised, modular air-cooled condenser (ACC) which is easy to build and robust in performance. It is used in waste-to-energy, biomass, small size electrical power plants and industrial co-generation. Hexacool® induced draft configuration saves up to 15% fan power consumption.
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.
