In 2015, Alfred University chose Bailey Thermal Logic Electric Front Loading kilns to outfit their department. This is the first time in their history that they selected a manufactured front loading electric kiln for their kiln room instead of building their own. They ordered a total of seven Thermal Logic Electric Kilns, including a 61" interior front loading sculpture kiln and a 51" interior 2 car shuttle kiln. The Alfred kilns run constantly, and they demand the very best in dependable performance. The Alfred staff saw great benefit to the Bailey hard element holder system, and all the other features of sustainable electric kiln design.

The Bailey Thermal Logic is undoubtedly the best electric kiln ever built!

Sometimes a product comes along that stands way out from the pack because there are so many improvements and innovations. The Bailey Thermal Logic Electric Kiln is one those products.

Bailey just redefined the standards for excellence in large electric kiln design. Not just by a little, but by a lot. The Bailey Thermal Logic Electric Kilns are a sustainable kiln design, built for a lifetime of heavy use.

The Bailey Thermal Logic electric is an ENERGY SAVER kiln and a sustainable design, with many features to promote beautiful results, easy repairs, easy service and a lifetime of use.

Advantage 1: The Bailey Hard Element Holders

Imagine a hard element holder so strong that it can withstand over 22 lbs of direct force and not fracture or chip.

Imagine this same super strong hard element holder being able to be lifted out instantly! If you need to inspect an element, remove debris, or if a glazed ceramic piece accidentally fuses to it, you won't have a problem. You can inspect or replace the ingenious Bailey hard element holder in seconds. No tools, no complications. Innovation at it's best!

Consider what this means. Now the most vulnerable part of the kiln, the element retention system, is incredibly strong and easily serviced. You can keep your kiln looking as good as new indefinitely. This is pure Bailey logic.

Advantage 2: Better Heating Efficiency

Here is another huge benefit of the Bailey Hard Element Holder system: Better Heat Transfer. Look at the illustration and note that every element slot in the brick has been cut at a unique 90 degree angle. The radiant heat from the element and hard element holder can fan right out to provide maximum exposure into the load. This greatly improves heating efficiency. Other front loading kilns have their elements buried in the brick. That causes the heat from the elements to absorb into the insulatong bricks quickly, saturating them, and so diminishing the IFB insulating capabilities and increasing the heat loss. The Bailey energy saver design further promotes energy efficiency by keeping the elements on the interior face of the brick. Note how the Bailey hard element holders and elements are not buried in the brick, and how they extend into the kiln chamber so they can radiate their heat immediately into the load. Brilliant!

Advantage 3: Bailey Long Life Electric Elements

Thermal Logic elements are massive, about 5/8" in diameter!. Just compare the size of the Thermal Logic elements to a typical competitor's elements. We use thicker wire, and more of it for extra acceleration power. It's like having a bigger engine under the hood. We also calculate the elements so there is less stress on the wire as it heats. You might call it a "cooler burn" because instead of making less wire work harder, we have more wire working less. The end result is much longer element life and a kiln built for speed. You spend more initially, and save dramatically long range.

Advantage 4: More Room for Stacking Shelves

How many times have you scraped your hands on the wall of a kiln, or bumped the wall with the shelf as you stacked the load? Plenty! No wonder, there isn't enough room! The walls of the typical electric kiln get damaged as a result of stacking in a cramped space. Bailey has implemented a very logical concept... it's called "more room". By leaving 2" from the wall to the shelf, stacking becomes much easier. Not only do you protect your hands and the walls, it promotes better heat uniformity in the chamber.

Advantage 5: Replaceable Wall Bricks

Even if bricks are damaged, no problem. Bailey designed the kiln without mortar. With the Bailey Easy Repair system, every brick in the wall or floor can be removed and replaced no matter where it is, and without dismantling the entire kiln. How is this possible? Bailey secures all the kiln brick with pressure systems and unique external anchors that are easily accessable. The result is a truly sustainable kiln, with an easy repair system designed to last forever because it is so easily serviced.

Advantage 6: Quick Change Front Wall Bricks

This is another "easy repair system" of the Bailey Electric Kilns. The bricks on front loader side walls are always the most vulnerable. Students often damage them from repeated impacts from shelves as the kiln is loaded and unloaded. If the walls are mortared together, you have no way to repair it. Bailey has engineered a new way to secure the front wall brick so they can be easily changed in a matter of minutes. This keeps your heat seals positive and protects the frame.

Advantage 7: Reinforced Fiber Gasket System

Another Bailey innovation is the front fiber roof gasket. This gasket has a dot pattern made of a hard ceramic material that protects the fiber and prevents abrasion. It is also designed to allow the fiber gasket to remain flexible so it won't crack as the door compresses against it and is secured prior to firing. This top horizontal gasket is designed for fast convenient replacement. It only takes a couple of minutes and no mortar is required.

Advantage 8: Stainless Steel Brick Protectors

The Thermal Logic has stainless steel edge protectors that guard against side impacts on the brick. This is another area that often experiences collision and damage during countless loading and unloading procedures. The stainless steel edge protectors absorb the impact so the brick remains unharmed.

Advantage 9: Built in Spy Fume Hood (optional)

Each spy port has a stainless hood directly above it which collects escaping fumes and heat. The heat and fumes are channeled into the spy hood and directed up into the overhead residual hood (optional). This is the most comprehensive ventilation system that provides complete fume removal.

Advantage 10: Built In UV Shields (optional)

What a great idea! Bailey has innovated another first, the built in UV shields. Now you don't have to go searching for UV glasses to view the cones. Each UV shield is sandwiches between protective clear Shields, and the stainless steel outer frame pivots up so you can withdraw the spy plug for viewing the cones. Note: The spy plug was removed for this photo, but should only be removed momentarily for viewing cones and put back promptly.

Advantage 11: Residual Hood (optional)

The Residual Hood (A) overlaps the door and fastens to the top of the kiln. All of the exterior walls of the kiln are hollow. Air intakes at the bottom of every exterior wall and door cavity so the heat travels out the top of the frame and directly into the collection hood. Residual fumes are also collected from the door and spy hoods. An (optional) draft inducer (B) is needed to pull away the fumes to the outside if you don't have an existing appropriate draft system in your facility.

The motor for the residual fume removal can be controlled by the Bailey Thermal Logic Controller. See below for information.

Advantage 12: Negative Pressure Fume Ventilator (optional)

The Negative Pressure Fume Vent pulls firing fumes directly from the inner kiln chamber as the firing progresses. It extracts noxious fumes that may accumulate during the firing, keeping both the firing chamber and classroom air clean, while protecting the outer frame from corrosion. You can buy the premounted package with the sheet metal vertical chase (D) and high exit for the pipe (C), or just the standard negative pressure unit for attaching to an existing kiln room wall. A flexible hose (included) is stretched to connect a small vent hole in the rear of the kiln to the negative pressure unit. The operation of the Negative Pressure Unit can be controlled by the Bailey Thermal Logic Controller when the (optional) AC outlet feature is ordered. See below. 

Advantage 13: Easy Change Thermocouples

(E) The thermocouples are serviced from outside the main control panel. This makes it easy to change a thermocouple during the firing. A Plexiglass pivoting cover locks the thermocouple in position.

Type S Thermocouples (optional)

We offer Type S thermocouples as an upgrade for kilns in active kiln rooms where the kilns are used constantly. Type S thermocouples are far superior, keep their temperature accuracy with intensive use and last many times longer compared to Type K thermocouples.

Advantage 14: Computer Controlled Vent Outlet (optional)(F)

When the (optional) AC Outlet box is ordered, the Bailey Thermal Logic Controller can be programmed to switch both the Residual and Negative Pressure fans on and off to synchronize with the firing. The AC outlet also is convenient so the blowers can be unplugged if they need servicing. A green panel light is also included with this package and will illuminate when the fume systems are active.

Without the AC controlled outlet, the user must manually turn the fume extraction devices on and off.

Advantage 15: The Thermal Logic Door System

There's more than meets the eye! Like the main frame of the kiln, all the bricks in the Bailey door are held under compression with ingenious methods of spring loaded compression. No mortar is used. You can adjust bricks to get a perfect heat seal, and you can replace bricks at any time. Future service is made simple.

Most larger models of the Thermal Logic Electric will have elements in the door. Some kilns don't require a door element for heat uniformity or heating.

The spy ports are larger than the small round style, so you have an easier job viewing the cones. The inner wall of the port is beveled so you can have a wider view. The top and bottom of the ports are made of alumina shelf so there won't be abrasion from the spy plug removal and replacement over the years. The exterior of the door has the hollow wall cavity so heat is directed into the residual hood for efficient removal.

NOTE: Bailey doesn't use fiber doors as we find in school situations that fiber is not well suited. It is easily damaged, and can be over compressed. The door area is a high activity zone where it is easy to brush up against. Putting a hard coating on the fiber is superficial at best, and there are future issues of shearing off. Insulating firebrick is ideal. It is an equal insulator, it is resilient to rubbing against, bumping, and impacts. We have coated the IFB doors (without elements) with an emissivity reflective surface to enhance the energy efficiency.

For safety, a limit switch is located at the bottom of the door to turn the power off to all elements once the door is cracked open.

Advantage 16: Above Floor Base Element

Bailey has innovated an above floor element system for better firing efficiency. Since the element is situated above the floor, the heat radiated by the element goes directly into the load instead of radiating it into the insulating brick. The element is so simple to replace, it just wraps around high alumina posts that define the pattern you see. Protective alumina tubes are used to prevent glaze from being accidentally dropped onto the element at the side wall (where the element feeds into the master control box). The entire wrap of the element is protected once the bottom shelves are in place. The bottom posts (1-3/8" high x 2.25" square) are included. Note: Some models of smaller kilns do not need a base element.

Advantage 17: Easy Access Control Panel

When you eventually need to service an electric kiln, you appreciate it when the manufacturer makes your job easier. That's exactly what we have done. The large control panel hinges open to provide ample room to maneuver to all of the components. Every wire is individually numbered, and a wiring diagram is attached inside every unit. The Thermal Logic circuitry is really a thing of beauty. Fuses, relays, elements junctions, and contactors are all nicely organized and accessible. Electrician's smile when they open our panel, because they appreciate the meticulous care in the design and layout of our circuitry. We make their job easier.

16 Segment Programmable Control System

The Bailey Thermal Logic programmable controller stores (6) user programs, (2) of which can have up to 16 segments and the other four have 8 segments. There are (4) preset programs (slow or fast bisque, slow or fast glaze), delayed start functions, skip step, and more.

Smaller kilns- under 30" Interior Height- have 2 zone control while taller kilns have 3 zone control. Red panel lights indicate the cycling activity of the various heat zones. This is further visual confirmation that the zones are active and functioning properly. Under the red Zone Control panel lights, a green panel light indicates that the Fume System is active.

All of our designs start with a shelf pattern. The options for stacking loads are: 22x22, 24x24, 26x26 and 28x28.

Each shelf pattern has a 2" clearance from the wall to the load (Load = shelf pattern x height). Some companies rate a kiln by the total interior size of the chamber, not the actual payload area where you place your kiln furniture and pottery.

Bailey provides extra tolerance from the wall to the shelf for easy accurate placement of shelves when stacking and better heat transfer. Consequently, there is slightly more chamber space that is left open. You can’t put larger shelves in a kiln designed for a smaller shelf size. The reason is, we have calculated the BTU’s necessary (watts per square foot) to heat the kiln “load” properly. The shelf area with pots are the “load”, which is a mass that has to be heated up. This requires a ratio of BTU’s to heat in up in a timely fashion. If you did use a larger shelf to place more pots, it would throw the ratio of power to load off, thus slowing down the kilns heat building properties.
