Infrared Industrial Tunnel Ovens Horizontal

EUROLINIA infrared tunnel electric heaters (EIT-GS) are designed for technological processes of vulcanization of organosilicon rubber of the cable shell in a continuous mode. Focused infrared radiation of high-power density allows high-speed uniform heating of the shell material to the vulcanization temperature.

Our IR tunnel ovens share the same horizontal modular design and can form a production line consisting of several infrared tunnel sections. Each section is equipped with a pneumatic lifting device for product loading or an emergency stop. In most cases, first two sections act as a shock-tunnel with temperatures of 650-750 degrees C, second and third sections complete the vulcanization process with stabilization temperatures of 200-300 degrees C. Cable passes in one run through the shock tunnel, while in the other two (or more) stabilization sections cable can pass up to 3 times to allow longer exposure time.

Infrared tunnel length can be increased by attaching additional sections (from 1 to 8 sections). This allows you to synchronize the duration of heating with the desired speed of the product movement through the heating chamber.

The following table shows an estimated (meters per minute) production speed for silicone cables (2-7mm OD diameter) using our standard EUROLINIA EIT-GS tunnel consisting of 4 IR sections*:

EUROLINIA’s tunnel ovens are equipped with original ceramic ICH-100 series emitters, which can provide up to 750C temperatures (compliant with international dimensional and wattage standards, CE certified).

They are installed inside the polished stainless-steel reflectors bundled with intermediate reflecting plates. Radiant heat reflected from the surface of the heated material goes back to the heaters and reflectors, providing the so-called thermo-resonance effect. This allows to redistribute and equalize the power of infrared radiation over the heated surface and provide high intensity heat that translates into higher production capacity. Infrared rays overlap in the center of the heating chamber, thus providing unmatched efficiency.

EIT tunnels can be equipped with a block of guide rollers from the side of the cable entrance into the tunnel and a block of guide rollers from the side of the cable exit from the tunnel providing the possibility of a three-fold passage of the cable in the IR tunnel. This allows to increase the exposure time of the cable in the heating chamber and use less sections of the IR tunnel, which saves space and customer’s expenses. The roller blocks are mounted on the frame of the installation tunnel RU-1 (RU-2). The design of the guide rollers is developed for the customer's task.

At EUROLINIA we develop and build custom horizontal IR tunnels ovens that exactly match your application. Please send us technical process requirements and material details to get your calculation. We provide complete technical coverage and support for the whole service life of our equipment.
