INTRODUCING
Plume Abatement and
Water Conservation Solutions
/We’re pulling the plug on the plume. /

Let’s Clear the Air…
For decades, cooling towers’ cold-weather condensation plumes have
been a major problem. At best, they’re unsightly; at worst, they impair
visibility and waste water. Which make them a particular worry around
airports and other environmentally sensitive areas.
At SPX Cooling Technologies, we’ve made it our mission to eradicate
as much of the plume as possible – while conserving significant
amounts of water along the way.
And we’ve succeeded.
Two Ways to Tame the Plume
For years, SPX’s coil-based hybrid cooling towers have
been a highly popular choice. Now, our NCWD tower
represents our most advanced application of this
technology. SPX’s hybrid technology adds a heated
dry air stream to our coil system, keeping the plume
undersaturated, even upon mixture with the ambient air.
Therefore, visible plume is practically eliminated.
Another option is our new Air2Air™ technology, which
comes at plume abatement from a slightly different, but
similarly effective, angle. Air2Air uses heat exchanger
packs to radically reduce condensation and keep the
plume in check.
Both solutions can also conserve substantial amounts
of water. And no matter which solution you choose,
you’ll be helping to make “plume history” – by helping
to make the plume, well... history.

If you’re concerned with reducing visible plume or saving water, let
SPX Cooling Technologies show you how to make our solution, your solution.

Our Hardest Working Technologies in Plume Abatement
and Water Conservation
NCWD:
Assembled on Our Site,
Not Yours
The new Marley®NCWD package cooling
towers are configured for applications of 500
tons or greater – yet, remarkably, are factory
assembled. This significantly broadens the
usability of wet/dry towers from “critical
applications only” to more mainstream projects
and installations.
By combining direct contact (evaporative)
and indirect contact (dry) heat exchangers
in a parallel arrangement, the NCWD’s
crossflow system can result in water savings
as high as 20%* versus conventional cooling
towers – while markedly limiting visible plume.
In addition, the NCWD line offers:
• Energy-efficient operation
• Lower maintenance requirements
• Cost-effective installation
• For those using chemical water treatment,
less blowdown and thus less chemicals
Air2Air:
Saving Water,
A Lot of Water
Our new, patented Air2Air system uses a series of
PVC heat exchanger packs in the tower plenum to
condense moisture before it escapes. The result:
A substantial reduction in plume emission.
But there’s more good news. Air2Air can reduce
your cooling tower’s water consumption by up
to 30% annually*, making it the obvious choice
anywhere that water conservation is a prime
concern. And Air2Air can be used on either new
or existing towers.
Because Air2Air is a fully integrated system,
it’s more reliable than exclusively coil-based
systems, which means:
• Simpler hydraulics for simpler operation
• Fewer moving parts, requiring
less maintenance
• No freezing worries

the impact Air2Air can have on your planned or
existing facility, and to sign up for updates on new
Air2Air installations, visit www.spxcooling.com/a2a.
