The Deep Mega Coil for Tall Vessels, Totems, and Sculpture
Most kilns are built around width. The Jen-Ken AF 2431 Mega Coil is built around height. At 31" deep, this kiln can fire pieces that simply won't fit in standard studio kilns. Tall vases, totem sculptures, large floor vessels, multi part figurative work, you name it. If your hands have been making the work but your kiln has been forcing you to keep it short, this is the kiln that lets you go vertical.
Same Mega Coil technology that makes the Jen-Ken Mega Coil series last 10 to 15 years longer than similar size kilns on the market. Six oversized super heavy gauge Mega Coils, one per full brick, with more element material than standard coils so they take longer to wear out. When the day comes that you do need a swap, the color coded wiring uncouples in seconds and you can change a coil yourself in about 10 minutes.
Inside, you've got a 24" wide by 31" deep chamber with 8.11 cubic feet of capacity. The 3" firebrick walls hold heat well, keep firings efficient, and let the elements work less than they otherwise would. The kind of construction that adds up to years of extra service.
The AF 2431 fires up to 2300°F (Cone 8), perfect for earthenware, low to mid fire stoneware, glaze work, and bisque firings. Runs on a standard 240V at 45 amps with a NEMA 6-50 plug, 10,800 watts.
Included with every order
A lid lifter to take the weight out of opening the kiln, a heavy duty stand sized for this model, the wall hanging digital Orton controller, the full operator manual, a solid state relay (SSR) for tighter temperature control and longer element life, a 2 year limited warranty through Jen-Ken, and free freight shipping to the US Lower 48.
Who Is This Kiln For?
The AF 2431 Mega Coil is built for a specific kind of potter or sculptor. Here's how to tell if that's you.
✓ Potters making tall vessels and vases
31" deep means you can finally fire those tall floor vases, tall lidded jars, and architectural vessels without compromising your designs to fit a shorter kiln.
✓ Sculptors working in clay
Totem pieces, figurative work, and multi section sculptural builds all fit in the 31" depth. No more cutting your work apart just to fire it.
✓ Production potters who fire often
The Mega Coil technology saves you years of element replacements and downtime, and the deeper chamber lets you stack more shelves for big loads of smaller work too.
✓ Artists who want a kiln that lasts
If you're investing in a kiln you plan to keep for 20+ years, the Mega Coil technology and self serviceable coil swaps make this one of the most maintainable kilns in the catalog.
The AF 2431 ships with the wall hanging digital Orton AutoFire 12 Key standard. This controller mounts on the wall away from the kiln heat, keeping its components cool and extending its life. It comes loaded with full cone fire schedules in slow, medium, and fast, plus 9 user programs for custom firings, and a 60 amp mercury relay built in. It also tracks the cost of each firing, the time it took, and the temperature you achieved, useful data if you're watching margins. Upgrade options include the AutoFire Slide touchscreen and the TAP Smart Controller with Wi Fi.
