Model JD2927-JH  - JH Series Crystalline Glaze Kiln with extra power for fast heat up, K25 brick for reduced brick shrinkage at high-temperature soaks, Quad Super Heavy Duty Elements, Multi-Program Three-Zoned Genesis Touchscreen control, 2-1/2" brick sides and bottom and a 3" top for heat balancing and fast cooling, and type S platinum thermocouples. The panel on this kiln is a DaVinci panel with 50 amp power contactors and cords. 29" Diam x 27" High (10.3 cubic feet). This is the only standard kiln we use a sidebar to support the lid (because the 2-1/2" brick needs that extra support - not shown in photographs). Direct power connection. Cone 12. The JH Series is specifically designed for crystalline glaze firing. There are three type S thermocouples. No charge for 3-phase versions. (Not listed to UL499). For export: see Crating Charges and Export Options in the Accessories Tab for crating charges.

All JH Series Kilns include Zone Genesis Touchscreen Control

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.
Angled Control Panel
EASY TO SEE AND PROGRAM THE CONTROL. Angled control panel makes viewing control and programming easier.
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.
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.

Durability

Type S Thermocouple
HIGH TEMPERATURE WORKHORSE. Type S Platinum Thermocouples are the best high-temperature thermocouple for ceramics
Quad Element Design
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.
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.
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.
Solid Super-Strong Aluminized Steel Stand
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.
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.
Extra Case Clamps
Three case clamps per 9" high kiln section are redundant safety for your L&L kiln.
Corrosion Resistant Case
KEEP YOUR KILN LOOKING NEW. Corrosion resistant materials and methods result in a long-lasting kiln.

Serviceability

Easy to Remove & Service Control Panel
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.
Reversible Bottoms
OOPS... JUST TURN IT OVER. The bottom can be easily reversed in case of a firing mishap.

Ease of Use

Easy-Open Spring-Assisted Hinge
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.

Performance

Thermal Ceramics Firebrick
K23 firebrick combines good insulation with strength

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.

Controls

DynaTrol Keypad Control
Traditional 24-button Keypad control. This control can be substituted for any Genesis full-sized control.
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.

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.

Power

120 Volt Power Supply & Electrical Noise Filter For Automatic Kilns
This option helps protect your control from electrical noise
