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.
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 Platinum Thermocouples are the best high temperature thermocouple for ceramics
Each kiln sections plugs into the Jupiter control panel. Easy to remove or change kiln configuration.
Wiring is neatly laid out using National Electrical Code and UL499 Standards
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.
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

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.
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 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.
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.
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.
Special brick coating hardens and seals brick for durability and cleaner operation.
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.
Three case clamps per 9" high kiln section are redundant safety for your L&L kiln.
Corrosion resistant materials and methods result in a long-lasting kiln.

Ease of Use

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

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

Performance

K23 firebrick combines good insulation with strength

Support

Most L&L Kilns have a three-year limited warranty.
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.

Elements

APM elements increase element life in difficult applications

Vents

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

Kiln Furniture

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.
These safety gloves are perfect for handling hot work when unloading a kiln.

Controls

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.
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 acts as an upper limit back up to the main control. Back up contactors are also available.
Control, monitor and record data for up to 10 kilns from your computer for a one-time price.

Power

This option helps protect your control from electrical noise
Powered bottoms increase power and can aid uniformity in large kilns

Miscellaneous

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.
This special Seismic Kiln Rack and Brace is designed to prevent a kiln from falling over during an earthquake.
Unpowered rings can extend the height of our Jupiter kilns.
