CDQ
dehumidification
Cool, dry, quiet with Trane rooftop units
The Trane CDQ™ desiccant wheel is used to
enhance the dehumidification performance of a
traditional cooling coil. The wheel is configured
in series with the coil (see RTU Airflow Path
illustration) such that the “regeneration” side
of the wheel is located upstream of the coil
and the “process” side of the wheel is located
downstream of the cooling coil. The wheel
recirculates the water vapor trapped
downstream of the cooling coil back into
the air upstream of the coil where the coil
removes it through condensation.
This process is accomplished without the
need for a second regeneration air stream.
The addition of the CDQ desiccant wheel to
the system enhances the dehumidification
performance of the traditional cooling coil.
For units with less that 40 percent outside air,
CDQ can greatly improve the latent capacity of
the unit. This results in a lower sensible heat ratio
(SHR) without the addition of reheat.
Developed in collaboration with the U.S.
Department of Energy through Oak Ridge
National Laboratory.

Part load energy savings
Adding part load humidity control will add
more energy no matter how it is done. Trane
CDQ™ diers from hot gas reheat because it
will increase the latent capacity. Reheat does
not eect the latent capacity of a unit, it simply
makes the unit run longer. Thus CDQ will run
less than hot gas reheat and produce drier air.

Humidity-sensitive application
For applications requiring humidity control
24/7 and 35-55 percent RH, a Trane high-
eciency rooop unit (RTU ) with CDQ
dehumidification will:
• Allow downsizing 15-33 percent
• Improve latent capacity 40-160 percent
• Lower dew points 2-5° F
• Reduce cooling energy 10-30 percent
• Reduce reheat and total energy 30-90 percent
CDQ curbs for rooop units
To achieve these performance levels, a
high-eciency Trane rooop unit must be
used with a CDQ curb section. The CDQ curb
section is manufactured by our partner, Thybar
Corporation. The two components are designed
to go together with no field modifications
required. Together, they comprise a CDQ
system that can be used for new installations
and retrofit applications.
