Control

DynaTrol Multi-Program Zone Control
DynaTrol with 4 Easy-Fire programs (Slow Bisque, Fast Bisque, Slow Glaze, Fast Glaze), 6 custom programs, PreHeat, Delay, Program, Segment Review, and Diagnostics. Zone control included on most kilns. Also see Genesis Touch Screen Option with Phone App for Remote Monitoring.
Automatic Zone Control
No need to pay extra for this important feature! Zone control on an electric kiln gives you the utmost in 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.
Type S Thermocouple
Type S Platinum Thermocouples are the best high temperature thermocouple for ceramics
Angled Control Panel
Angled control panel makes viewing control and programming easier.
Easy to Remove & Service Control Panel
Control panel pulls down easily and remain perpendicular to the element box for very easy access. All wiring is neatly laid out in a professional and industrial way with color coding and numbering for easy repair and troubleshooting. Best of all the double panel design results in cooler panels and longer control and relay life.
On-Off Switch and Panel Fuse
All L&L Kilns come with an on-off switch and panel mounted control fuse. We do not rely on the kiln control to keep the kiln off.
Mercury Free Contactors
Power Relays are mercury-free to comply with increasing regulation and concern about mercury. Solid State Contactors are available as an option on most L&L Kilns.

Durability

Quad Element Design
The Quad Element System provides a massively robust element for long life under production conditions. Standard on eQuad-Pro and JH Series. Optional on most other kiln series.
Hard Ceramic Element Holders Make L&L Kilns More Durable
Durability, Repairability, Better Heat Transfer. The smooth, hard surface of the inside ceramic channel allows the elements to expand and contract freely. No pins! The dense ceramic holders extend element life because they do not insulate the hot elements from the kiln interior.
Solid Wide-View 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 competitor's kilns.
Solid Super-Strong Aluminized Steel Stand
Aluminized stands are extremely strong and corrosion resistant. They offer solid support under the kiln - unlike spot-welded angle stands that are common in the industry.
Molded Ceramic Element Connections
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.
Proprietary Reflective Coating Hardens & Seals Brick
Special brick coating hardens and seals brick for durability and cleaner operation.
Stainless Clips Secure Lids to Bands
Stainless Steel clips help the lid stay secure and durable. This extra step ensures that the lid won't slip out of the stainless steel band.
Extra Case Clamps
Three case clamps per 9" high kiln section are redundant safety for your L&L kiln.
Corrosion Resistant Case
Corrosion resistant materials and methods result in a long-lasting kiln.

Ease of Use

Easy-Open, Easy-Load Spring Hinge
Feather-light spring hinge allows full access without a side support bar - for easy loading. Standard on all 10 and 12 sided polygonal kilns.

Serviceability

Reversible Bottoms
The bottom can be easily reversed in case of a firing mishap.

Performance

Thermal Ceramics Firebrick
K23 firebrick combines good insulation with strength

Support

Three-Year Limited Warranty (Standard)
Most L&L Kilns have a three-year limited warranty.
Superior Technical Support
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 you answers and help.

Controls

Genesis Touch Screen Control
The new Genesis control from Bartlett includes a touch screen interface and WIFI connectivity added to the proven software of the DynaTrol. A phone app allows you to monitor your kiln remotely.
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.
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.

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.

Miscellaneous

Rolling Kiln Stand
L&L's rolling kiln stand features heavy gauge (14 ga) galvannealed steel construction with multiple bends for extra strength, steel swivel locking casters, integrated vent collection box support, and guide rails for the kiln. Each size is fitted to the kiln.
Crating Charges and Export Options
Export crates, ISPM-15 Skids for export, and special pallet designs for unloading Easy-fire kilns without a forklift.

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).
Vent Doubler System
The Vent Doubler allows you to use one vent on two kilns.

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.
