ater. We can’t live without it. And, in many parts of the world, we can barely get enough. The
impact on industry is huge. Short water supplies can limit plant production, block industrial growth
and expansion, drive up treatment costs for the water that actually is available, and heavily burden existing
infrastructures. Meanwhile, the more usable water an operation demands, the less energy-efficient it
becomes. But now there is real help on the way.
Enter SPX Cooling Technologies. Our unique Air2Air water recovery system does what no other cooling
technology can: reduce your cooling tower water consumption by up to 30% annually.*
That level of reduction can add up quickly, fueling your productivity and growth while increasing energy
efficiency. And Air2Air systems can be used in either new or existing cooling towers.
* Dependent upon system operating conditions and local weather conditions.

The Air2Air water recovery system allows cooler, ambient air to condense much of the moisture before it exits
the tower. The system can be installed on a single cooling tower cell, or on an entire tower, depending on the
required water return rate.
And what to do with the water you save? It can be cycled back into the cooling system. Or piped away as a
pure water stream for boiler make-up or other plant uses. Or even returned to the local aquifer – it’s that pure.
