JD230-3-EZ Electric Kiln

Model JD230-3-EZ Jupiter Automatic Kiln with with Multi-Program Three-Zoned DynaTrol mounted in a separate easy-to-maintain control panel mounted on the kiln (which fires cool because of the air space between the controls and the kiln). Sectional and modular construction allows future expansion. Kiln comes with hard ceramic element holders, thermocouple protection tubes, strong solid-top stand, and solid peephole plugs. 22-3/8" diameter by 27" high (6.7 cubic feet). 3" K23 brick. Uses Easy-Fire e23T elements for higher power (48 amps). NEMA 6-50 single phase or 15-50 three phase 6 foot power cord included. C-MET-us listed in the USA & Canada. Cone 10 for all voltages.

Three 9” high sections stack on top of each other. The hinge and element connection box hold the entire kiln together as an integrated unit. The kiln is very easy to assemble and disassemble. The kiln sections plug into the separate control panel.  More about sectional construction...
Stainless steel wrapped around shaped firebrick. There are three adjustable clamps welded to each casing. All assembly is with stainless steel screws. The kiln sections sit on a separate stand.
Spring loaded "Easy-Lift" lid opens with a feather-lite touch. The strength of the hinge allows the lid to rest back away from the opening without a support arm that would get in the way of loading the kiln.
Heavy-duty 14 gauge full solid stand with multiple bends for strength. Legs bolt on with heavy 1/4-20 stainless bolts. The metal is aluminized for good corrosion resistance.
A proprietary brick coating is applied to all interior surfaces of the kiln. This is put on before the element holders are inserted. This coating penetrates the firebrick and fuses the surface on a microscopic level which helps prevent dusting and crumbling of the fragile firebrick.
Solid ceramic peephole plugs with full 1” diameter. Three total: one per section.
Three control zones with three separate thermocouples. More about zone control.
8 Ga Type K Exposed Thermocouple in Mullite Protection Tube (4.5" long /114mm)
Mounted on control panel
All controls and components are mounted in a separate control panel that is mounted to the element connection boxes with an air space in between. The control panel is hinged for easy access and maintenance. Each kiln section plugs into the control box. Control box can be easily removed for servicing. On/off switch and control fuse are included. More about Jupiter plug-in control panel.
Control box cover is hinged for easy access to inside of control box. Entire control box is removable.

Durability

Corrosion resistant materials and methods result in a long-lasting kiln.
Three case clamps per 9" high kiln section are redundant safety for your L&L kiln.
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.
Industrial grade ceramic terminal blocks make changing elements easy.
Special brick coating hardens and seals brick for durability and cleaner operation.
Aluminized stands are extremely strong and corrosion resistant. The offer solid support under the kiln - unlike spot-welded angle stands that are common in the industry.
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.
Mullite protection tubes extend thermocouple life and keep kiln clean. The mullite protection tube keeps the metal oxides of the thermocouple tip from dropping off and contaminating your work.
Thick 8 gauge thermocouples last a long time. Special Limit of Error to ANSI MC96.1 specifications is used.

Performance

Zone control gives you the utmost in controllable temperature uniformity. The DynaTrol separately measures temperatures in the bottom, middle and top of the kiln and automatically adjusts the heat output of three zones during the entire firing.
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.
K23 firebrick combines good insulation with strength

Ease of Use

Feather-light spring hinge allows full access without a side support bar - for easy loading. Standard on all 10 and 10 sided polygonal kilns.
Solid large non-tapered peepholes allow a wider view into the kiln.

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.

Serviceability

Wiring is neatly laid out using National Electrical Code and UL499 Standards
Each kiln sections plugs into the Jupiter control panel. Easy to remove or change kiln configuration.
The bottom can be easily reversed in case of a firing mishap.
Sectional kiln construction make Jupiter kilns easy to move, set up and disassemble for maintenance.

Safety

Most L&L kilns are MET listed to UL499 standards. Listed kilns include Easy-Fire. Jupiter. DaVinci, School-Master, Liberty-Belle. Hercules & Easy-Load kilns areMET-Us Listed for US only.
Power Relays are mercury-free to comply with increasing regulation and concern about mercury in schools
All L&L Kilns come with an on-off switch

Elements

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 elements increase element life in difficult applications

Thermocouples

Type S Platinum Thermocouples are recommended for high fire applications

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.

Vents

The L&L Vent-Sure Kiln Vent is the most powerful downdraft kiln vent on the market today. That means you have more flexibility in the installation.

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

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.

Cone 10 Kiln wash is used to coat shelves to prevent sticking of glaze.

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. 

Control, monitor and record data for up to 10 kilns from your computer for a one-time price.

Electronic High Limit Back Up Control acts as an upper limit back up to the main control.

The Eurotherm 2604 is an indutrial-grade PID control with two or three zone cabability built in.

Power

L&L's 480 volt option can include a NEMA 1 control panel

This option helps protect your control from electrical noise

Powered bottoms increase power and can aid uniformity in large kilns

Miscellaneous

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.
