ACC/Heller
Sustainable high performance
Dry power cooling systems of GEA (air-cooled condensers and Heller indirect dry cooling systems) allow for setting up power plants based on steam cycle in areas scarce of cooling water. As water availability is becoming an issue, water prices are rising, legislatory restrictions may apply on water usage for power cooling purposes, dry cooling methods are becoming increasingly important.
Ninety years of experience using air cooling for power plants has now been concentrated in the Business Unit ACC / Heller of GEA Heat Exchangers segment. This enables us to offer individual solutions for fossil-fuelled, nuclear, geothermal or solar thermal power plants.
Business Unit ACC / Heller also offers cooling systems to plants with stringent noise restrictions and cooling systems that cope with complex load requirement. Our references include installations located on every continent, operating in various ambient air temperatures ranging from -62 to +50°C. Flue gas discharge via natural draft cooling towers is also an area where Business Unit ACC/Heller excels. If applied with coal fired units, our Heller dry cooling towers lend itself to the integration of wet scrubbers thus reducing investment costs, operation and maintenance costs. Our air-cooled condensers are available with a number of different finned tube systems allowing us to satisfy individual customer requirements.
Innovative engineering solutions optimize our dry cooling installations. Thanks to an improved exhaust steam duct routing for large ACC plants, steam side pressure loss is reduced and the efficiency of the entire installation is increased, resulting in additional savings in equipment and erection costs. Bionic design of the ACC steel substructure reduces the number of foundations and support columns thus saving material costs.
Business Unit ACC / Heller is a reliable partner of the power plant industry. Engineering, project management, delivery, technical assistance during installation and commissioning, delivery of spare parts, expert assistance in operational issues are all in the experienced hands of our companies, providing our customers with the comfort and assurance they need.
