SPX Cooling Technologies Unveils Breakthrough Water Recovery System at New Mexico Power Plant

First Full-scale Installation of SPX’s Patented Air2Air™ Cooling Technology
Will Reduce Power Plant’s Annual Water Consumption by up to 20 Percent

NEW ORLEANS, LA – December 11, 2007 – SPX Corporation (NYSE:SPW)
today announced that its cooling technologies business has completed the installation of its
breakthrough water-saving technology for wet cooled power plants.  SPX’s patented
Air2Air™ water recovery system enables power plants to recover much of the water
evaporated in a standard cooling tower and, in doing so, reduce their annual water
consumption by as much as 20 percent.  The first full-scale installation of the new cooling
tower cell is now online at Public Service of New Mexico’s (PNM) San Juan Generating
Station.

SPX (Exhibitor Booth #2001) issued the announcement on the opening day of
POWER-GEN International 2007, the world’s largest power generation event, taking place
in New Orleans, Louisiana.

“The Marley Air2Air™ water recovery system is the most advanced water-saving
solution available for wet cooled power plants, and it reduces water consumption while
maintaining overall steam turbine efficiency,” said Tom Dendy, Director of Global
Marketing & Development at SPX Thermal Equipment & Services.  “The typical 500-
megawatt, coal plant in the U.S. uses roughly 30,000 tons of water each day. A cooling
tower fitted with SPX’s Air2Air™ technology can reclaim up to 10,000 tons of water each
day, or enough to provide 6,000 households with water.  On an even broader scale, we
believe our technology can make a significant contribution to global water conservation
efforts.”

As the seventh-largest coal-fired generating station in the western United States,
San Juan is PNM’s primary power generation source, serving 58 percent of PNM’s
customers.  The plant’s newly enhanced cooling system uses the evaporation of water to
dissipate the heat from power plants’ steam condensers.  By evaporating a portion of the
circulating water flow through the cooling tower, the remaining water is cooled.  SPX’s
Air2Air technology then recovers a portion of the evaporated water, condenses it, and
retains it in the tower system.

“In addition to reducing water consumption and treatment costs, coal-fired power
plants that utilize SPX’s Air2Air water recovery system can achieve greater overall
productivity, and even replace more costly means of generating pure water,” added Dendy. 
“Recovered water can be returned directly to the tower basin, or even piped away as a pure
water stream for boiler make-up or other plant uses.”

The full-scale water conservation installation at the San Juan Generating Station is
being funded in part by a three-year research grant from the U.S. Department of Energy,
National Energy Technology Laboratory (DOE/NETL) – which estimates that U.S. power
plant cooling towers evaporate three billion gallons of water each day.

The performance of the tower and water recovery system at San Juan is being
monitored remotely with a wireless satellite monitoring and collection system supplied by
SPX Flash Technology.  Utilizing the latest in wireless detector technology, design
engineers from SPX Cooling Technologies can continuously monitor the performance and
operation of the unit and provide live feedback and operating recommendations to plant
operators in New Mexico.

“With the cooperation of PNM and SPX Flash, we are able to closely monitor and
validate the performance of the water recovery system,” said Glenn Brenneke, Vice
President of Research & Development for SPX Thermal Equipment & Services.  “This
will enable us to collect a complete set of operating data to assess the system over a full
range of plant and weather conditions.”

SPX’s relationship with PNM dates back to 1975, when the company undertook
installation of a wet/dry tower at the San Juan station to address the issue of water
availability.  Completed in 1978, the tower began commercial operation in 1979.  Testing
in 1980 found the tower exceeded design requirements in both thermal performance and
water conservation.
