Carbell® kiln

One of our most innovative designs is the Carbell® Kilns The success of this design made it a standard kiln within the ceramic industry with worldwide popularity and it is still used today in industries right across the world.

Carbell® Kilns are also referred to Top Hat kilns, but they were developed initially by NUTEC Bickley who trademarked the Carbell® name. The industrial Kiln is lifted vertically clear while kiln cars are loaded and unloaded on rails. Once loaded, the kiln is lowered down onto the cars; when the bell is fully lowered, a seal blade on the bell structure engages the sand seal trough around the perimeter of the car.

Nutec Bickley developed this concept and has delivered hundreds of Top hat kilns to a variety of ceramic product manufacturers worldwide. The Carbell kiln is designed for a stable and repeatable seal between the kiln and kiln car, while providing a strong and robust structure for refractory insulation.

The blade is made of alloy steel and is water cooled, providing a robust and durable seal mechanism. When the kiln is down and sealed, the temperature is increased to top temperature and down again following a set cycle automatically.

The Carbell® Kilns is designed for a stable and repeatable seal between the kiln and kiln car, while providing a strong and robust structure for the refractory insulation. This is essential for firing at high temperatures but is also beneficial at lower temperatures since the industrial kiln seal is more reliable than a shuttle style of door seal.

The combination of improved sealing, burner arrangement and downdraft design results in the best possible temperature uniformity for a batch type kiln of this size.
