NUTEC Bickley Tunnel Kilns

Tunnel Kilns comprise of a set of kiln cars or trucks passing through a hot tunnel on rails. Product is placed onto the kiln cars usually with setting furniture. The temperature rises towards the middle and then cools towards the end so the temperature profile is created by different temperatures at different sections of the kiln down its length. This type of kiln is suitable for firing big volumes of products with excellent consistency for the products. 

NUTEC Bickley's Tunnel Kilns are manufactured for ceramic production at temperatures of up to 1800°C (3270°F). With NUTEC Bickley’s equipment, process variables are under tight control from the beginning to the end of the cycle, assuring superior quality of your finished products. Our Tunnel Kilns count with high levels of control resulting in top quality products and a low energy usage offering lower cost production.
