Heavy duty elements last up to four
times longer than most kiln elements
Production kilns are in constant heavy use.
All DaVinci Production Kilns feature special heavy duty elements that
use heavy gauge premium Iron-Aluminum-Chrome alloy elements with a very
low watt density. The lower the watts per square inch of element
surface area the cooler the elements can run and the longer they
last. DaVinci elements last 3 to 4 times longer than most typical
kiln elements, a fact that has been proven in over ten years of
producing DaVinci kilns. There are three individual elements per
9" high section.
3" Hand Picked Firebrick
All DaVinci Production Kilns use 3" thick hand picked premium
firebrick. This is more energy efficient than 2 1/2"
firebrick when doing soaks (although total energy usage is about the
same a s2 1/2" brick if you just shut off kiln at final set
points. Also 3" brick allows for a slower natural cool
down. The shallow cut required by the unique Super 3000 Dyna Glow
element holds makes brick even more efficient.
Brick hardened with Special Coating
The firebrick has a reflective ceramic coating.
This reduces dusting, aids brick life and increases efficiency and
temperature uniformity because of improved radiation within kiln.
True Cone 10 design
They have a higher KW power rating (watts per radiating
muffle inch) than almost any other ceramic kiln. In addition
bottom elements are available on larger models for even faster heat up
and better control over cold spots in tightly packed kilns. The
heavy duty elements and high temperature elements holders are also a big
plus for high fire use.
Square/Rectangular "Plus" Design:
Utilizing sound engineering principles, the "square
plus" DaVinci design was created to provide a very stable square or
rectangular structure. It is far stronger than oval kiln designs
where the front can cave in with too much pressure. Loading of
many types of ware is far more efficient in a square or rectangular kiln
than a polygonal or oval kiln. The extra "plus" space
created by the slight arch in the sides helps natural convection inside
the kiln without taking up valuable loading space. This natural
convection promotes even firing of ware.
Sectional Construction: Easy to move, set up and repair.
Sections can be removed for easy loading of kiln. You can move
even the largest DaVinci kiln through a normal door. The sections are
remarkable stable even when turned on edge because of the strong arch
design. Sections plug into separate instrument box with flexible
cords eliminating any plug to receptacle line up problems. It is easy to
stack the sections and then, after the kiln is lined up to your
satisfaction, you can plug the sections into the instrument box. This
also makes it very easy to remove a section for loading the kiln. In
fact, we design the counterbalanced hinge to be self supporting from the
third section so that section four (on the 36" high kilns) and
section five (on 45" high kilns) can be easily removed for loading.
Handles are included on the sections.
Versatility of Size
DaVinci Production Kilns are sectionalized. You can
increase or decrease the size by adding or removing a section.
Save on electric bills for small loads yet have ample firing
capacity. Add capacity in the future.
Easy to Move and Set Up
Because the kilns come in 9" high sections, they can
easily be moved and set up. They can be moved through any standard
32" doorway because even the largest sections can be turned on
their side. There are four chest handles on each section.
Corrosion resistant case materials
Case is stainless steel. Heavy welded angle iron
stand will last life of kiln. Stands have full plates of
aluminized steel under the bottom brick. This allows bottom brick
to move freely while expanding and contracting.
MultiZone Control (automatic or manual)
Automatic kilns include Dynamic Zone Control for
automatic adjustment of top to bottom temperatures. Achieve better
than 1/2 cone accuracy. Manual kilns include Infinitely Variable
Input Zone Switches (one for each section) which adjust thermal
gradients to prevent uneven heating. Use with our Tru-View
multi-thermocouple system. Manual kilns include pilot lights for
each zone. Automatic Dyna-Trol includes digital indicators.
Floor Mounted Detached Control Panel
The control panel is mounted on the floor away from kiln heat for more
reliable operation. (The photos do not show this). Switches
and sensitive components last longer. Kiln sections plug into
panel with flexible cords. Panel can be easily sent for factory
repair if ever necessary.
Power relays - Industrial Quality Wiring
All power is switched to the elements with power relays.
Zone switches last much longer. Wiring connections are positive to
stable components. Each circuit is branch fused. The
instrument panel is well ventilated.
Counterbalanced "Easy Load" Lid System
The unique "Easy Load" spring loaded
counterbalanced lid system provides several important advantages.
The lid can be opened with one hand by almost anyone. Because the
lid closes gently there is less wear and tear on the lid and lip and
less chance of breaking the lid. The hinge post is adjustable up
and down. This allows the hinge system to be adapted to your kiln
if you add a section. There is a safety catch to lock the lid in
the up position. The hinge and lid are attached to the bottom
three sections. You can remove the upper sections of 36" and
45" high models for easy kiln loading without dismantling the
counterbalanced hinge or removing the lid. The hinge system is
very heavy duty, made of welded heavy structural steel, and will last
the life of the kiln.
"Super 3000" Dyna Glow Element holders:
The element holders have a 3000 degree F ceramic body
with silicon carbine which provides extremely high temperature
resistance and superior heat transfer capability. The large holder
accommodates the large heavy duty element used in the DaVinci
kilns. It also makes element replacement easy. Any number of
element replacements will not affect the hard ceramic element holders or
brick walls, unlike other kilns where elements are pinned into the soft
firebrick grooves. Brick interior stays "like new" for
many years! Dyna Glow element holders reflect the infrared heat
instantly into the kiln and therefore operate at a lower temperature
relative to the internal kiln temperature. They require less
firebrick insulation to be cut out. This means L&L Kilns are
more efficiently insulated than other kilns of this type. Hard
smooth surface allows the elements to expand and contract freely.
No loose particles will fall in the kiln and ruin
ware.
DynaTrol automatic controller, with Dynamic Zone Control
Automatically provides accuracy of better than 1/2 a cone top to
bottom. It features an Easy-Fire cone fire mode, and a separate
sophisticated "Vary-fire" programmer. This allows you to
have 6 separate repeatable storable programs with up to 8 segments
(cooling and heating ramps, temperature setpoint and an optional hold
time per segment.) You can soak at a low temperature for a long
time, and then automatically ramp up to your high fire at different
rates. It also allows a controlled cool down to avoid heat
shock. Dust sealed panel, delay start, "cone offset",
temperature shows in F or C, automatic restart after brief power
interruption, change of program during firing, program review, audible
temperature alarm, segment review.
Detachable Instrument Panel Stands off case -
stays cool: The air space between the panel and kiln
keeps components cool. Switches, controls and other sensitive components
last longer. Panel can be sent to factory for repairs if ever necessary.
All models have contactors and branch fusing and are a direct hook up to
your power source. This is done to National Electrical Code and UL
standards. All panels are floor mounted and include holes for mounting
to floor.
Tru-View Pyrometer System allows you to see and adjust
gradients
The Tru-View pyrometer system for manual kilns, with up to five
thermocouples and a selector switch, allows you to "see" the
temperature gradients in your kiln and adjust them out with the infinite
zone switches. It can also act as a check against your Dawson Kiln
Sitter. Pyrometer has a heavy duty bakelite casing with precision
ALNICO magnetic mechanism.
Large One Inch Diameter Peepholes, one per section.
Reversible Bottom The bottom can be reversed in
case of a firing mishap.
