A-frame Air Cooled Condensers

The traditional A-Frame is a state-of-the-art air-cooled condenser (ACC). It’s suitable for small to large power plants in a large variety of conditions (low ambient temperature, high wind, high seism, low noise and many others).

ACCs immediately condense the steam turbine exhaust flow and return condensate to the boiler without water loss. The steam is directly condensed in air-cooled finned tubes without using an intermediate surface condenser.

Features ofan Air CooledCondenser

An air-cooled condenser (ACC) is made of modules arranged in parallel rows. Each module contains several fin tube bundles. An axial flow forced-draft fan located in each module, forces the cooling air through the heat exchange area of the fin tubes. An ACC installation consists of:

  • a supporting structure
  • a steam ducting from the steam turbine interface
  • auxiliaries such as condensate and drain pumps
  • condensate and duct drain tanks
  • air evacuation units
  • related piping works and instrumentation



The air-cooled condenser prevents unnecessary water usage from the condensing power cycle. The uniform steam distribution and total absence of backflow of steam, results in an increased performance and prevents air accumulation, flooding, sub-cooling and freezing.


Air-cooled condenser solutions are flexible in power plant site selection. Benefit of the flexibility in module arrangements tailored to the best usage of your available plot.

Cost efficient

Benefit of a decreased lead time for plan permitting. The finned tubes from the air-cooled condenser have an excellent manual or semi-automatic cleaning system.

High quality

SPG Dry Cooling air-cooled condenser solutions contains top quality single row condenser fin tubes. They offer an excellent corrosion and freezing resistance.
