Thank you for purchasing a Wood-Mizer
Dehumidification Kiln and taking the first step
towards making the lumber industry cleaner and
more efficient! Years of development, innovation
and the highest quality materials have gone into
building your kiln, but it’s our dedication to
efficiency that sets Wood-Mizer’s kilns apart from
the rest and makes your system the best on the
market.
During kiln drying moisture in green lumber is
evaporated into the air increasing the humidity
inside the chamber. If the air becomes oversaturated
the lumber can’t continue to dry so moisture must
be periodically removed from the chamber. In
a conventional kiln moisture would be expelled
through venting. Venting causes a signicant loss of
heat requiring more energy to bring the kiln back up
to temperature.
Your Wood-Mizer Dehumidification Kilns doesn’t
waste energy through venting. Instead a
refrigeration system condenses the excess moisture
which is drained off and the existing heat energy is
recovered to be reused. After the moisture is
removed and heat is reintroduced to the dry air it is
pumped back into the kiln chamber to start the
process over. Unlike conventional kilns the heater in
your Kiln is only used during the initial warm up
and, sometimes, when temperature increases are
desired during the cycle, saving you time and
money. But that’s not all your new kiln has to offer!
Though Wood-Mizer kilns don’t rely on venting to
get rid of moisture, a Vent System is supplied to add
extra control of your kiln temperature. If the internal
kiln temperature exceeds what’s required, these
vents can be opened to remove excess heat and
bring the temperature back to where it needs to be.
And finally Wood-Mizer offers a wide variety of
upgrades and accessories to enhance your kiln
drying experience. See the upgrades and
accessories section on page 34 for more
information.
Concrete oors with insulation installed underneath
is recommended for best results. However if the
kiln is going to be on an existing concrete oor,
the insulation may be omitted. Concrete must not
extend beyond the kiln walls.
Wood oors may be used but must be built to
construction guidelines (see Pg 3)
If the kiln chamber is a freestanding outside
building, the attic space must be well ventilated
through the eaves. This is done to avoid any
moisture buildup in this space, which will condense
on the cold roof, dripping onto the insulation.
An interior kiln can have the ceiling insulation open
to the atmosphere.
Build ceilings to construction guidelines. (Pg 3)
At the front of the kiln chamber install bay/loading
doors with at least two sides hinges, and a center
door latch to close (recommended). Top hinged or a
lift o doors are also acceptable.
At least one access door should be installed in the
back of the chamber to allow for service of the
dehumidier and/or lumber monitoring.
All installed doors must:
•
Be built to construction guidelines. However they
may be lightened by increasing the stud spacing and
using 3/8” plywood. The lighter weight will reduce
the load on the hinges
Please read through carefully as some options
may not apply.
By purchasing a Wood-Mizer Kiln you have the support
of Wood-Mizer’s service team, the very same
professionals that built and tested your unit.
