Model e28T-3 Easy-Fire Automatic Kiln with with Multi-Program Three-Zoned DynaTrol mounted in an easy-open cool-firing piggy-back control panel that is angled for easy viewing of control. Kiln comes with hard ceramic element holders, protected thermocouples, strong solid-top stand, easy-lift spring hinge, and solid peephole plugs. 28" diameter by 27" high (10.2 cubic feet). 3" K23 brick. 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 three phase models- see below for single phase.

Note about  e28T-3 Easy-Fire Kiln on 1 phase power

The e28T-3 kiln is only rated for Cone 8 when the power supply is 240 volts, 1 phase. It is only rated for Cone 5 when the power supply is 208 volts, 1 phase.

A cone rating should be several cones higher than the cone you plan to fire to. Elements in a kiln that is rated for cone 8 will not last very long when firing to cone 5 or 6 especially with heavy loads.

That said- if you answer yes to any of these following questions, you probably want to go with a more powerful L&L, like the eQ2827-3 or the JD2927-3-QD (if you need UL listing). Both of these kilns, in the single phase versions, have more power (watts) than the e28T-3 and will consistently deliver the power you need to reach Cone 6. On the other hand, both the 240 and 208 volt three phase versions of the e28T-3 deliver plenty of power (watts), so this note does not apply to three phase e28T-3 models.

  1. Do you fire to Cone 5 or 6 at least twice a month?
  2. Would you fire with more than 3 layers of kiln shelves in a kiln this size?
  3. Can you get a larger circuit breaker? (80 amp breaker for 240 volts, 1 phase OR 90 amp breaker for 208 volts, 1 phase)

NOTE: If the largest circuit breaker you can have is a 60 amp breaker on 240 volts, 1 phase power, you should either get a smaller L&L- like the e23T-3, or count on changing the elements often- about every 30 or so firings. Another help is to get the Quad element option. With the Quad element option the elements will last longer but you won't get any more power in the kiln (so you could still get slow firings).

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.
Angled control panel makes viewing control and programming easier.
Control panel pulls down easily and remain 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.
Ceramic protection tubes protect the end of the thermocouple.
Thick 8 gauge thermocouples last a long time. Special Limit of Error to ANSI MC96.1 specifications is used.
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

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.
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.
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.
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

Sectional kiln construction makes kilns easy to move, set up and disassemble for maintenance.
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.
The combined experience at L&L Kilns in kilns, ceramics, electrical engineering and process engineering is unsurpassed.

We also include well-vetted information and wisdom from our industry partners to ensure our customers have access to all the basic information necessary to be successful from the first firing.

Safety

Most L&L kilns are MET listed to UL499 standards. Listed kilns include Easy-Fire Pottery Kilns, Easy-Fire-XT Square Pottery Kilns, eQad-Pro Professional Kilns, eFL Front-Loading Kilns, Jupiter Sectional Kilns, DaVinci Square & Rectangular Production Kilns, School-Master School Kilns, Fuego Home Craft Kilns, Doll-Test Kilns, and Liberty-Belle Craft Kilns. Easy-Load Production Front-Loading kilns are MET-Us Listed for US only.

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. 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.

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 Doubler allows you to use one vent on two kilns.
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.
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

Miscellaneous

This special Seismic Kiln Rack and Brace is designed to prevent a kiln from falling over during an earthquake.
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.
