Control

The Genesis control includes a touchscreen interface and WIFI connectivity. The intuitive interface is easy to use and understand. A free phone app allows you to monitor your kiln remotely.
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.
EASY TO SEE AND PROGRAM THE CONTROL. Angled control panel makes viewing control and programming easier.

Durability

HIGH-TEMPERATURE WORKHORSE. Type S Platinum Thermocouples are the best high-temperature thermocouple for ceramics. Standard on JH Series kilns; optional on most other kilns.
BEST ELEMENT SYSTEM FOR HIGH-TEMPERATURE FIRING. 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.
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.
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.
FULL SUPPORT STAND. Aluminized stands are solid and corrosion-resistant. They offer solid support under the kiln - unlike spot-welded angle stands that are common in the industry.
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.
KEEP YOUR KILN LOOKING NEW. Corrosion resistant materials and methods result in a long-lasting kiln.

Serviceability

THIS IS THE SAFEST AND EASIEST KILN TO WORK ON. The Control panel pulls down easily and remains 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.

Ease of Use

WIDE OPEN - EASY-TO-LOAD. A feather-light spring hinge allows full access without a side support bar - for easy loading. Standard on all 10 and 12-sided polygonal kilns.

Support

THIS IS REALLY IMPORTANT WHEN YOU CONSIDER THE ELECTRONIC CONTROL. Most L&L Kilns have a three-year limited warranty.
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.

Controls

Traditional 24-button Keypad control. This control can be substituted for any Genesis full-sized 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 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 are recommended for high fire applications. NOTE: Price of upgrade is per each thermocouple.
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

L&L's rolling kiln stand features heavy gauge galvannealed steel construction with multiple bends for extra strength, locking swivel casters, integrated vent collection box support, and guide posts for the kiln. Each size is fitted to the kiln.

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 the control.
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 heat-resistant gloves for 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.

Power

This option helps protect your control from electrical noise
