Dyna-Glow Element Holders- an L&L exclusive! - Hard ceramic element holders keep elements in place and protect fragile firebrick during element changes.

Quad Element System- 4 rows of elements in each 9" kiln section. Quad elements are wound with thicker gauge wire and have a lower watt density than L&L's standard elements. With coils measuring almost 1/2" diameter, these heavy-duty elements stand up to the rigorous demands of Cone 10 Crystalline firings.

K-25 Brick- 2-1/2" Walls & Floor and 3" Lid are all constructed with 2500 degree rated firebrick to better withstand firing to Cone 12. 

Dyna-Trol Multi Zone Controller- Easy to program with 4 Preset Programs for standard firings and 6 User Programs for custom firing profiles. With up to 8 Segments, custom programs allow control of heat-up and cool-down, heat soaks, delay start and more. Multi Zone control monitors and adjusts temperature independently in each section of the kiln to keep the chamber firing evenly.

Type S Thermocouples- More accurate and longer lasting at Cone 10 and above than standard Type K thermocouples.

Spring-Assist Hinge- Makes opening the lid easy and supports it securely. The hinge opens beyond 90 degrees for easy access to the chamber while loading and unloading.

Sectional Design w/Plug-in Control Panel- Sections are completely seperate from the Control Panel for easy disassembly when moving or servicing the kiln. Each section has a cord that plugs into a receptacle on the main panel. Once the cords are unplugged, the main control panel can be removed and the kiln sections seperated. (NOTE: The kiln's hinge system must also be removed for disassembly.)

Electrical Specifications for Kilns

The chart above lists the available electrical specification options for this kiln. You must order the kiln with the proper wiring specifications for it to function properly. These specifications are determined by the power supply that you will be connecting the kiln to. Review this information with your electrician to determine the proper Voltage and Phase for your kiln. The choice of V/Ph determines the Amperage draw of the kiln and the size of the breaker needed. A kiln requires a breaker that is 20% above the actual amperage draw. Be sure that you can supply sufficient power for the kiln you choose. The chart also indicates the NEMA plug configuration for the kiln –or- if it must be Direct Wired. Voltage and Phase selection must be confirmed in writing with all kiln orders. If you have any questions concerning this information, please call us at 800-431-6067.

Thank you.
