DaVinci Kilns Features

Square and rectangular DaVinci kilns use shallow arches for their sides. This is very stable and much stronger than oval kiln designs where the weak front can cave in under pressure (from loading or moving). Loading of many types of ware (for instance plates and tiles) is far more efficient in a square or rectangular kiln than in a polygonal or oval kiln. The extra “plus” space created by the arch in the sides helps natural convection inside the kiln without taking up valuable loading space. This natural convection promotes even firing.
Spring-counterbalanced brick lid
The lid can be opened with one hand. Because the lid closes gently there is less wear and tear on the lid and rim. In addition, the lid is fully supported around the perimeter with structural steel members. This takes stress off of the fragile firebrick. The hinge post is adjustable up and down. This allows the hinge system to be adapted to your kiln if you add or remove a section. The heavy-duty hinge system is made of welded structural steel. The lid is worry-free firebrick. A rigid steel channel frame surrounds the lid. Stainless steel channels hold the lid to this frame. Even if the door cracks it will maintain its integrity and stay in place. Adjust size by adding sections All DaVinci production kilns are made in 9” high sections that come apart. You can increase or decrease the size by adding or removing a section (without removing the lid!)
Heavy-duty welded frame bottom
The welded stand will solidly support the weight of the kiln and the heaviest load in your kiln.
Easy to move and set up Because the DaVinci kilns come in 9” high sections, they can be easily moved and set up. Move them through any standard 32” wide doorway.
Elements last up to four times longer
Heavy gauge premium elements with a very low watt density last 3 to 4 times longer than most typical kiln elements, proven in over 20 years of firing. There are three elements per 9” high section. Branch fusing Each element circuit or zone is separately fused in a branch circuit.
Handheld DynaTrol zone control with “Dynamic Zone Control”. (See page 10). An On/Off switch turns power off to the kiln when not using it. A control fuse protects the control circuit.
Floor standing detached control panel
The control panel mounts on the floor - away from kiln heat. Switches and sensitive components last longer. Kiln sections plug into the panel with flexible cords. The panel door is hinged and all wiring is neatly laid out for easy maintenance.
Many options and sizes
There are 20 sizes up to 34-1/2 cubic feet (plus custom sizes - see page 45). Standard crosssections are 22” square, 26-1/2” square, 30-1/2” square, 26-1/2” by 35-1/4” rectangular and 30- 1/2” by 43-1/2” rectangular. Heights of 18”, 27”, 36” and 45” are standard with other heights custom. All models are available as manual kilns. Bottom elements are available on many models. There are many other options which you can find in the L&L Custom Kiln Catalog.

PERFORMANCE
FIRES TO CONE 10 - 2350F - 1287C

• The DaVinci production kilns are unequivocally rated for cone 10 operation (2350F, 1287C).
• They have a higher K.W. power rating than most other ceramic kilns.
• Power Bottoms are available.

3" OF PREMIUM FIREBRICK

• 3" Premium grade K23 firebrick is standard

LARGE 1" DIAMETER PEEPHOLES

• Peepholes are a full one inch diameter and are not tapered.
• Better view inside kiln
• Less chance of breakage

MULTI-ZONE DESIGN

• Whether you order a manual or an automatic, every DaVinci kiln is multi-zoned.
• Each 9" section (and optional powered bottom) has its own separate contactor or manual infinite switch.
• In the case of the four or five section automatic kilns the middle sections operate together as one zone.
• For automatic kilns the optional powered bottom is tied into the bottom zone. However, the DynaTrol allows you to adjust how much of the bottom's power is used (from 10% to 100%).
  >VERSATILITY OF SIZE - SECTIONAL CONSTRUCTION
  
• All 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.
• Control boxes are sized for 5 zones (even on smaller kilns) and extra circuits can be added by the factory in the future if ever needed.

SQUARE AND RECTANGULAR "PLUS" DESIGN

DaVinci kilns feature a unique shallow arch design that provides a very strong structure and promotes natural convection

Automatic DaVinci Kilns Features
>DYNATROL AUTOMATIC CONTROL - WITH FOUR EASY CERAMIC PROGRAMS

>The DynaTrol with "Dynamic Zone Control" replaces manual switches
and the Dawson kiln sitter/timer.

Operation of the kiln, including zone control for even firing, is completely automated.

There are four easy-to-use "Easy-Fire" ceramic programs.

There are six user defined programs for more sophisticated firing.

DYNATROL IS IN HANDHELD PANEL
On DaVinci kilns the DynaTrol is mounted in a separate hand-held box that plugs into the power contactor panel.

This control box can hang on the wall or a supplied bracket that attaches to the counterbalance pole.

>DYNAMIC ZONE CONTROL FOR EVEN FIRING

Dynamic Zone Control automatically controls a top, middle and bottom zone for accuracy better than 1/2 cone top to bottom.

L&L does not charge extra for this great feature - others do.
