Areas of a structure that can benefit from the addition
of heat for drying include crawlspaces, basements, or
parts of a building where heat is not available.
Cold air actually impairs the evaporation of moisture
from materials. Warm air from the Dragon helps
airmovers and dehumidifiers evaporate more moisture
from materials and remove it from the structure. For
instance, raising the temperature of an area with the
Dragon by just 10°F (from 60°F to 70°F) can increase
the evaporative potential of your existing drying
system up to 45 percent.
The specific target drying temperature will vary
according to the conditions of each drying job.
Determining, creating, and maintaining the optimum
drying conditions on a job—including temperature and
relative humidity—is your responsibility.
For best results when using the Dragon for drying,
you should understand the basic principles of
psychrometry—the science of drying. You should also
know how to use moisture detection instruments to
track the moisture content of a structure throughout
the entire drying process. You can learn these skills
and more in an IICRC-certified Applied Structural
Drying (ASD) course. To learn more about ASD
courses, contact the Dri-Eaz Education Department at
1-800-575-5152.
With this in mind, there are some general principles to
keep in mind when using the Dragon. You should try to
stabilize the temperature of the affected area near the
ideal operating temperature of your drying equipment.
Most dehumidifiers perform at their best between 70°F
to 90°F. The added heat from the Dragon will increase
the rate of evaporation by decreasing the relative
humidity of the affected area. Be certain that your
combination of airmovers and dehumidifiers is
powerful enough to keep the relative humidity well
below 60%RH to avoid secondary damage to the
structure and contents.
