About Dry
Cooling Solutions

Dry cooling regroups several technologies that cool or condense fluid within a heat exchanger without consuming water. The heat exchangers are externally cooled by a cold air flow. Unlike wet cooling, the heated steam is cooled and condensed back into water in a closed loop system.

Dry cooling solutions can decrease total water consumption by more than 95%, this is the equivalent of the water consumption of several million people.


Difference between
direct and indirect
dry cooling

Direct dry cooling systems directly condenses the steam turbine exhaust flow returning condensate to the boiler without water loss. Steam is directly condensed inside air-cooled finned tubes without using an intermediate surface condenser.

Air cooled condensers are used in utility, industrial and renewables markets for large and small size plants.

SPG Dry Cooling designs, manufactures and constructs traditional A-Frame ACCs, as well as our innovative Hexacool®, ModuleAir®, BoxAir ACC®, W-Style ACC® and Natural Draft Condenser using high efficiency SRC® finned tubes.

The indirect dry condensing system couples an indirect dry cooling tower (IDCT) with a steam surface or jet condenser and is suited for large capacity condensing units.

Products for dry cooling solutions

Looking for a product that offers optimum energy savings and maximal comfort? Select your product and discover a wide range of benefits.

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.
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.
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.
