Control

Genesis Touch Screen Control
Automatic Zone Control
EVEN FIRING. MAKES LOADING MORE FLEXIBLE. ADJUSTS FOR ELEMENT AGING. No need to pay extra for this important feature! Zone control on an electric kiln gives you the utmost controllable temperature uniformity. The kiln control separately measures temperatures in the bottom, middle, and top of the ceramic kiln and automatically adjusts the heat output of three kiln zones during the entire glaze or bisque firing.
Industrial Wiring (DaVinci & Easy-Load)
PROFESSIONAL AND CLEAN LAYOUT. DaVinci Panels are wired to industrial standards with a good clean wire layout.
Floor-Standing Panel Away from Kiln (DaVinci)
ALLOWS THE SECTIONS TO PLUG IN WHILE SEPARATE FROM THE KILN. The control panel is mounted on a stand away from the kiln.
Mercury Free Contactors
HEAVY-DUTY. Power Relays are mercury-free to comply with increasing regulations and concerns about mercury. Solid State Contactors are available as an option on most L&L Kilns.
On-Off Switch and Panel Fuse
WHY WOULDN'T YOU HAVE AN ON-OFF SWITCH? All L&L Kilns come with an on-off switch and panel-mounted control fuse. We do not rely on kiln control to keep the kiln off.

Durability

Protected Thermocouples
KEEP YOUR WORK CLEAN. Ceramic protection tubes protect the end of the thermocouple. Keeps the oxide dust from the thermocouple tip from getting into the kiln while firing.
Heavy-Duty Type K Thermocouples
HEAVY-DUTY. Thick 8 gauge thermocouples last a long time. Special Limit of Error to ANSI MC96.1 specifications is used.
Hard Ceramic Element Holders Make L&L Kilns More Durable
NO PINS TO REPLACE AND DAMAGE YOUR FIREBRICK! Durability, Repairability, Better Heat Transfer. The smooth, hard surface of the inside ceramic channel allows the elements to expand and contract freely. The dense ceramic holders extend element life because they do not insulate the hot elements from the kiln interior.
Strong Arched Sides with Extra Airspace (DaVinci)
EXTRA SPACE GIVES YOUR WORK BREATHING ROOM. Arched sides on DaVinci kilns are very strong and promote good air circulation
Steel Frame Supports Lid (DaVinci)
STRONG PERIMETER FOR THE DAVINCI LID. A unique welded rigid frame supports the entire lid on a DaVinci kiln.
Welded Angle Iron Stand (DaVinci)
Welded heavy-duty stand supports heavy loads. Alumized top sheet reflects heat.
Molded Ceramic Element Connections
NO CRIMPING! EASY TO CHANGE. Industrial-grade ceramic terminal blocks make changing elements easy. All contact between elements and wire lugs is over a wide surface of heavily torqued stainless steel washers. Wires are not crimped to element ends as in some other brands. This means you can change elements yourself without buying an expensive tool or hiring a kiln repair person.
Solid Wide-View Peephole Plugs
STOP BREAKING PEEPHOLE PLUGS. Solid large non-tapered peepholes allow a wider view into the kiln. The peephole plugs are made from solid ceramic and are not as fragile as hollow-type plugs used on competitors' kilns.
Corrosion Resistant Case
KEEP YOUR KILN LOOKING NEW. Corrosion resistant materials and methods result in a long-lasting kiln.
Extra Case Clamps
Three case clamps per 9" high kiln section are redundant safety for your L&L kiln.

Ease of Use

Spring-Loaded Lid For Easy Opening and Gentle Closing of DaVinci
EASY-LIFT LID SAVES ON WEAR AND TEAR. All but the T3400 DaVinci lids can easily be lifted by one person. T3400 models need two persons to lift.

Serviceability

Sectional Kiln Construction for DaVinci Kilns
EXPAND AND CONTRACT YOUR DAVINCI KILN WITH THE ADJUSTABLE HINGE. Sectional kiln construction makes DaVinci kilns easy to move, set up and disassemble for maintenance. Kiln Sections all plug into a separate control panel making the kiln easy to take apart and reconfigure.

Support

Three-Year Limited Warranty (Standard)
THIS IS REALLY IMPORTANT WHEN YOU CONSIDER THE ELECTRONIC CONTROL. Most L&L Kilns have a three-year limited warranty.
Superior Technical Support
LET OUR EXPERIENCE WORK FOR YOU. The combined experience at L&L Kilns in kilns, ceramics, electrical engineering, and process engineering is unsurpassed. We work as a team to help you get your answers and help.
Visual Detailed Instruction Manual
LIKE HAVING A KILN LIBRARY AT YOUR FINGERTIPS. The combined experience at L&L Kilns in kilns, ceramics, electrical engineering, and process engineering is unsurpassed. We provide a visual parts list with photographs, part numbers, prices, and helpful information to reduce confusion when ordering parts. We also include well-vetted information and wisdom from our industry partners to ensure our customers have access to all the basic information necessary to be successful from the first firing.

Safety

Listed to UL499 Standard by MET
CERTIFIED SAFE. Most L&L kilns are MET listed to UL499 standards. Listed kilns include Easy-Fire Pottery Kilns, eQad-Pro Professional Kilns, eFL Front-Loading Kilns, Jupiter Sectional Kilns, DaVinci Square & Rectangular Production Kilns, School-Master School Kilns, Fuego Home Craft Kilns, and Doll-Test Kilns. Easy-Load Production Front-Loading kilns are MET-Us Listed for the USA only.

Elements

Quad Element Option
The combination of 1/2" diameter element coils, the doubled surface area of the Quad element design, and superior heat transfer of L&L's patented ceramic element holders, make this the best element system in the world today.
APM Sintered Powder Metal Elements
APM elements increase element life in difficult applications

Thermocouples

Type S Platinum Thermocouples
Type S Platinum Thermocouples are recommended for high fire applications. NOTE: Price of upgrade is per each thermocouple.
Pyrocil Metal Sheathed Industrial Thermocouples
Pyrocil thermocouples are sensitive but limited to about 2200°F but offer greater sensitivity to temperature change and so may be appropriate in applications below 2200°F that require sensitivity. NOTE: Price of upgrade is per each thermocouple.

Vents

Vent-Sure Downdraft Kiln Vent System
A Critical component in the longevity of your kiln!The Vent-Sure automatic kiln vent helps prevent corrosion on the inside and outside of your kiln.
Vent Control Programmed on DynaTrol & Genesis
The Vent Control allows you to automatically control the operation of the Vent-Sure kiln vent with one of the outputs from the DynaTrol (or Genesis).

Kiln Furniture

Furniture Kits
Kiln furniture kits are the recommended set of ceramic shelves, posts and kiln wash that go with each kiln model. These are for loading the work in the kiln.
Safety Gloves
These safety gloves are perfect for handling hot work when unloading a kiln.

Controls

Solid State Relays
Solid State Relays are quiet and result in longer element life because the switching time is so fast the elements don’t heat and cool as much the way the will with regular mechanical contactors. The whole system includes heat sinks, special fast acting fuses, cooling fan and extra safety relays.
Electronic High Limit Back Up Control
Electronic High Limit Back Up Control acts as an upper limit back up to the main control. Back up contactors are also available.
DynaTrol Keypad Control
Traditional 24-button Keypad control. This control can be substituted for any Genesis full-sized control.

Power

480 Volt Option
L&L's 480 volt option can include a NEMA 1 control panel
120 Volt Power Supply & Electrical Noise Filter For Automatic Kilns
This option helps protect your control from electrical noise
Powered Bottoms For DaVinci Kilns
Powered bottoms increase power and can aid uniformity in large kilns

Miscellaneous

Unpowered 4-1/2" High DaVinci Sections
Unpowered rings can extend the height of our DaVinci kilns.
Seismic Kiln Rack and Brace
This special Seismic Kiln Rack and Brace is designed to prevent a kiln from falling over during an earthquake.
