Air Cooling

Athens Power Station (2000) — plumeless ACC technology to meet clean air, low noise and aesthetic requirements. GEA’s first North American installation using ALEX heat exchanger technology.

Dighton Power Project (1997) — first U.S. merchant power plant, built without a power purchase agreement so the Owner could sell power on the open (spot) market. Owner elected to use dry cooling technology in order to expedite the permitting process.

El Dorado Energy (1998) — showcases modular construction ACC, the first of its kind, where fan modules could be built on the ground before being lifted and set on the structure by large cranes.

Exeter Energy Project (1989) — this PAC SYSTEM operates at a steam turbine exhaust pressure of 2.9 in. HgA at an ambient air temperature of 89° F for higher power production while saving the owner more than half the cost of an all-dry system.

Hunterstown (2001) — large combined cycle power station located in Pennsylvania (near Gettysburg) had very low noise requirements.

Linden Cogeneration Project (1991) — largest dry-cooled power plant in North America at the time of installation, this plant utilizes three ACC systems arranged in a contiguous structure. This project was among the first of GEA’s "low noise" condensers, requiring the use of specially designed fans.

Millmerran Power Project (1999) — 840 MW coal-fired plant located west of Brisbane in Queensland (Australia) required two ACC systems with modular construction features to maximize grade level assembly and installation productivity.

Moapa Energy Facility (2001) — located 20 miles north of Las Vegas, Moapa is the largest power plant in the world that was built as a full "merchant" facility (without a PPA).

Saranac Energy Plant (1994) — ACC comprised of 25 cells, designed to meet cold weather requirements.

SEMASS Waste to Energy Facility (1999) — low-noise design required PAC SYSTEM technology. Retrofit project increased condensing capacity by approximately 20%.

Streeter Generating Station (1994) — proximity to a highway where icing could occur meant converting this 20-year-old plant in Cedar Falls, Iowa, to GEA’s PAC SYSTEM by adding an ACC operating in parallel with the existing wet cooling system.

Tucuman Power Station (1997) — Pluspetrol Energy of Argentina wanted to convert their existing simple cycle power plant to a 450 MW combined cycle plant, but their well water supply could only provide about 50% of the water required for an all wet heat rejection system. GEA’s PAC SYSTEM satisfied these constraints.

Union County Resource Recovery Facility (2001) — ACC originally comprised of 9 cells, expanded to 12 cells. Complete overhaul of the plant’s Control Logic was part of this turnkey project.

University of Alberta (2001) — cogeneration plant needed to generate electricity during the day and supply steam (for heating) during the night for the campus.

Wyodak Station (1977) — 330 MW coal-fired plant, where ambient temperatures range from -48°F to 107°F and wind speeds can reach over 80 mph. GEA’s ACC systems have operated here successfully and reliably for more than 35 years without causing a single hour of forced outage.

Wet Cooling

Martin County Expansion — 22-cell fiberglass cooling tower designed to withstand hurricane force winds of south Florida.

INEOS Phenol Expansion — Original 6-cell Douglas Fir structure tower was expanded with two additional fiberglass cells.

Jasper County — NF-20 modular splash fill was provided to eliminate fouling problems. Along with the main, 11-cell fiberglass cooling tower, a 3-cell cooling tower was constructed for use with the turbine inlet air chilling system.

Forney Power Project — This 22-cell wood cooling tower is the longest continuous structure ever built by GEA.

Rhodia — Tear down and rebuild an existing 2-cell wood crossflow tower and replace with a 2-cell film filled counterflow tower with a fiberglass structure.

Metro Area Total Energy Plant — Cooling tower built to service a new chiller unit for the Metro Area Total Energy Plant which provides heating and cooling to all hospitals in downtown Boston, Massachusetts area.

PICO Power Project — Plume abated cooling tower with fiberglass structure was built with a dry cooling section designed to reduce the relative humidity of the exit air. This was necessary to prevent fogging conditions on nearby highways and the San Jose International Airport.

AES Hawaii — Located on the island of Oahu, Hawaii, this 200 MW coal fired power plant provides 16% of power for the island. A fiberglass cooling tower was built in 1999 to replace a deteriorating wood tower.

Plant Branch — This 32-cell tower with a water flow rate of 400,000 gpm was installed along the banks of Georgia's Lake Lanier. It is the largest mechanical draft cooling tower built by GEA.
