Your Kiln
How your Dehumidication Kiln Works
Thank you for purchasing a Nyle Dehumidication
Kiln and taking the rst step towards making the
lumber industry cleaner and more ecient! Years
of development, innovation and the highest quality
materials have gone into building your kiln. It’s our
dedication to eciency that sets Nyle kilns apart
from the rest making your system the best on the
market.
During kiln drying, moisture from green lumber is
evaporated into the air increasing the humidity inside
the chamber. The lumber can’t continue to dry if the
air becomes over-saturated therefore the moisture
must be periodically removed from the chamber.
In a conventional kiln moisture would be expelled
through venting. Venting causes a signicant loss
of heat resulting in a waste of energy to bring the
kiln back up to temperature.
Instead of venting, Nyle Dehumidication Kilns
utilize a refrigeration system that condenses the
excess moisture. This moisture is then drained o
retaining the existing heat energy. 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 Nyle 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 oer!
Though Nyle 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.
Finally Nyle Systems oers 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. By purchasing a Nyle Kiln
you have the support of Nyle’s service team, the
very same professionals that built and tested your
unit. Enjoy your new system!
Getting Started
Please read through carefully as some options may not apply.
Floors
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)
Ceilings
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
and drip onto the insulation.
An interior kiln can have the ceiling insulation open
to the atmosphere.
Ceilings must be built to construction guidelines.
(Pg 3)
Doors
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
dehumidier 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
• Have a vapor barrier.
• Have gaskets wherever the door meets the kiln;
this will give a good, airtight t.
• Have a scraper type weather strip to reduce air
leakage if door sill is not present.
