e28T-3 Pottery Kiln (289 Litres)

LEAD/SHIPPING TIME: 14-16 Weeks

Model e28T-3 Easy-Fire Automatic Kiln with Multi-Program Three-Zoned Genesis Touchscreen control mounted in an easy-open, cool-firing, piggyback control panel that is angled for easy viewing of control. Kiln comes with hard ceramic element holders, protected thermocouples, a strong solid-top stand, an 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. There are three thermocouples. No charge for 3-phase versions. 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 the following questions, you probably want to go with a more powerful L&L, like the eQ2827-3. This kiln has more power (watts) in the single-phase versions than the e28T-3 and will consistently deliver the power you need to reach up to Cone 10.

  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 this kiln?

  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 more often than normal. 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).

Genesis Touch Screen Control

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.

This controller will make firing kilns just a little bit easier in these ways:
*touch-screen technology for the user interface
*easy-to-follow screen descriptions
*different user-interface levels, which can be set to match the user’s firing knowledge
*graphical display of the firing process right at the controller
*Store up to 30 custom user programs
*Up to 32 segments per program
*Ability to make adjustment during a firing such as add segments, add temperature, and skip segments
*Built in diagnostics testing for use with a current sensor
*Alarm
*Error Codes
*WiFi enabled for easy software updating
*Register your Genesis on our web site or mobile app for remote monitoring of your kiln

Main Features

Delay Time

• Control when kiln starts and stops.

Preheat

• "Candling" fires kiln at 180°F for a time that you set.
• Completely dry out ceramic work before the main cycle begins.

Hold

• Control end of firing.
• Hold the final temperature for a time that you control.

Cone and Thermocouple Offsets

• Let you fine tune your firings.

Dynamic Zone Control

• The Genesis separately measures temperatures in the bottom, middle and top of the kiln and automatically adjusts the heat output of three separate heating zones even as the kiln is heating up.
• Kiln temperatures are automatically evened out to within 1/2 cone or better top to bottom.
• There are separate thermocouples (heat sensors) and contactors (power controls) for each of the three zones.
• You may place your load to best advantage without regard to temperature differences.
• There are adjustable offsets for each thermocouple which allows you to adjust uniformity within the kiln and match control performance with actual witness cones.

Other Important Features Of The DynaTrol

Four "Easy-Fire" Preset Firing Profiles

• This makes it easy to fire ceramics.
• Even people who are shy of programming can work with this control.
• Slow Bisque, Fast Bisque, Slow Glaze and Fast Glaze all have time proven profiles for the vast majority of ceramic firing.
• Just enter cone number and optional delay time, soak time, candling time and alarm.

Program Review

• See the entire program before or while running it.

Segment Review

• Lets you review the segment you are on.
• Also shows you what your current set point is during the program as it is changing.

Audible Temperature Alarm

• This can alert you at any point in program.
• For instance the control can alert you that the kiln is close to maturity so you can watch it reach final set point or use it to tell you when to turn off the vent.

Change of Program During Firing

• Make adjustments as needed.

Last Temperature Reached

• This is shown at end of firing program.

Cone/Temperature Equivalent Look Up Table

• Convert cone numbers to degrees.

Dust-Sealed Panel

• Graphically numeric keypad makes programming easy.

Error Checking can be turned off

• Error checks include stopping program if kiln is rising too slowly or if one zone is 100°F off set point as well as other error checks.

Automatic Restart

• This occurs after brief power interruption with alert. Control logic determines whether it is better to continue or shut down.

Thermocouple Burnout Protection

• Kiln shuts down automatically if all thermocouples burn out. Kiln continues to fire if one or two thermocouples burn out.

Two Key Start

• Optionally configure the control so it requires you to press two buttons to start it.

Digital Indication

• Configure temperature in either degrees F or C.
• Scroll through all three thermocouple readings to see what each zone is doing.

Cold Junction Compensation

• Automatically compensates for varying ambient temperatures to make control more accurate.
• Control can operate in ambient temperatures of 32°F to 125°F (0°C to 50°C).
• Segment review button lets you see ambient board temperature.

Electronic Control Matches Pyrometric Cone Performance

• This feature, licensed from Orton (Patent 4,461,616 & 4,730,101), adjusts the final temperature reached in an Easy-Fire profile based on the speed of the actual firing.
• It results in accurate automatic control of heat-work in ceramic firing.

Number of Zones is Programmable

• You can easily change the control from a three zone to a two or even single zone control.
• This is useful on L&L's unique sectional kilns where you can remove or add sections.
