TUNNEL KILNS FOR CERAMICS

Nutec Bickley offers a wide variety of tunnel kilns fabrication and car handling equipment for high volume ceramic production.

The tunnel kiln is designed to meet the customer’s needs as determined by their process and layout requirements.

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 tunnel kilns are manufactured for ceramic production at temperatures of up to 1,800°C (3,270°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.

Industrial kiln benefiting from the best technology

SCADA

With our SCADA systems, tunnel kiln operators are able to have complete control of their firing process, enhancing efficiency and productivity. Our latest Industry 4.0 developments integrate the latest tunnel kiln technology to not only monitor the process, but also to keep the tunnel kiln operating at peak performance with smart maintenance. All the data generated from the tunnel kiln during the firing process is stored in our SCADA system, which is then used to generate reports, graphs and intelligence data, to help customers in their decision making process.
