Jen-Ken Mega Coil 2822-3" Ceramic/Pottery Kiln

This kiln is built for busy ceramic studios, schools, and community programs that fire frequently and need reliable, efficient performance with minimal downtime. With a spacious 28" wide chamber and 22" depth, it comfortably accommodates larger work while staying ergonomic for loading and unloading.

Engineered for long service life, this model features Jen-Ken’s signature oversized Mega Coils — thick, heavy-gauge elements that last significantly longer than standard kiln coils. Better yet, they are designed for fast, simple replacement: most users can swap a coil in about 10 minutes, keeping your studio running without service calls or downtime.

A 3" brick body delivers superior insulation and energy efficiency for consistent firings, while solid-state relays come standard for quiet, smooth power delivery and extended electrical component life. Lid lifters are also included, making operation effortless even during long firing schedules.

This kiln excels at frequent Cone 5–6 production firing and is capable of reaching higher temperatures (up to 2300°F / Cone 8) when programmed slowly, making it ideal for studios doing functional pottery, glaze work, and repeated bisque cycles.

Choose the voltage that matches the electrical service where the kiln will be installed. Some kilns are available in only one voltage, while others can be ordered in multiple voltages. If both 120V and 240V are available, 240V is generally the preferred choice because it places less demand on your electrical system, while 120V offers the convenience of operating on a dedicated standard household circuit. If both 208V and 240V are available, select the voltage that matches your building's electrical service—240V is most common in homes, while 208V is common in many commercial, educational, and institutional buildings. If you're unsure which voltage you have, confirm it with your electrician before ordering.

Your kiln must be built to match the electrical service where it will be installed. Choose single-phase if that's what your building has (almost all homes do). Choose three-phase only if your building has three-phase power available. If both are available, three-phase is generally the preferred option. If you're unsure, verify the available electrical service with your electrician before placing your order.

Mechanical relays are standard and reliable. Solid-state relays (SSR) offer silent operation, faster cycling, greater precision, and longer lifespan—ideal for frequent or high-accuracy firings.

Not all kilns can use a collar, but Olympic’s Hot Box kilns can be ordered with a collar to expand versatility. A blank collar simply adds height to the firing chamber, while a bead collar adds the same height and includes a built-in bead or annealing door for quick-access lampwork projects.

This safety feature automatically cuts power to the heating elements whenever the kiln lid or door is opened. It prevents accidental burns, protects elements, and resumes power only when safely closed. (Also called an automatic lid shutoff on Olympic kilns.)
