Electric Tunnel Kiln: An Industrial Processes Workhorse

Tunnel kilns, silent workhorses of industrial heating processes, have revolutionized various sectors with their efficient, controlled heat treatments. At their core, kilns such as the electric tunnel kiln are elongated, continuous heating chambers designed for high-temperature applications, providing uniform thermal treatment to materials passing through them. 


Initially used in ceramics, the versatile design of the tunnel kiln has found applications in metals, glass, and even food processing. 

One advantage when compared with intermittent kilns is that these continuous kilns, as they are known, can be depended on for support of higher throughput rates, and they excel at efficient firing when dealing with higher product quantities. 

Tunnel Kilns for Industry: They’re Electric

These electric tunnel kiln variants operate on electricity, offering precise temperature control and reduced environmental impact compared to fossil fuel-based kilns. The advancements in kiln technology have enhanced their usability, making them indispensable for various industries. 

From art rooms to shops and manufacturing facilities, a large insurance carrier takes a look at safety, offering important tips for the use of kilns in settings like these. 

Ceramics and Pottery Manufacturing

The electric tunnel kiln can ensure consistent firing temperatures, essential for achieving desired material properties and product quality. In custom lab work, where precise control over firing cycles is crucial, these kilns play a pivotal role in creating specialized ceramics.

Metallurgical Processing

Industries dealing with metal refining, sintering, or heat treatment heavily rely on kilns like these kilns. A kiln such as this provides controlled atmospheres for processes like annealing, hardening, and tempering, ensuring the required mechanical properties and structural integrity of metals.

Glass Annealing and Forming

Glassmakers use kilns like the electric tunnel kiln to strengthen glass by relieving internal stress and improving durability.bility. Moreover, these kilns aid in glass forming processes, enabling the shaping of molten glass into desired configurations.

Heat Treatment and Industrial Processes

Industries requiring consistent heat treatments, such as in the production of refractories, bricks, and cement, benefit from the uniform and controlled heating provided by these electric types of kilns. Additionally, these kilns find applications in drying processes, enhancing efficiency and quality.

Advancements in Kiln Technology

The evolution of tunnel kilns has been marked by technological advancements aimed at addressing industry demands for efficiency, precision, and sustainability.

Sophisticated control systems equipped with sensors, PLCs (Programmable Logic Controllers), and AI-enabled technology enable precise monitoring and adjustment of temperature, atmosphere, and other critical parameters, ensuring consistent quality output. Advanced control systems with certifications and compliances such as Intertek UL 508A and ISO 9001:2015 are key. 

Customizable Kiln Solutions

At Deltech Furnaces, we know companies like yours depend on reliable partners who collaborate closely, to understand the unique requirements of individual customers, in order to tailor kiln solutions that optimize efficiency, quality, and cost-effectiveness.
