Narrow Product Infrared Heat Tunnels
Glenro’s infrared heat tunnels provide Proven Solutions® for heat processing narrow webs and fabrics, multi-pass fibers and tows, wire and other narrow product applications. Heat tunnels apply intense infrared energy to the product for uniform heating. Glenro offers standard heat tunnels, as well as custom designed units and complete infrared systems using this tunnel technology.
Heat Tunnel Model HT80XX
This heat tunnel incorporates Glenro’s rapid response heater technology. It comes standard with an insulated enclosure that is hinged, providing easy access to its interior for product threading and maintenance, and a control system.
Heat Tunnel Model HT4238XX-XX
This heat tunnel is designed with sinuated wire elements and heavy insulation for high temperature operation. It can process wider products or more passes of narrow products than the HT80XX design illustrated above.
Standard Heat Tunnel Specifications*
Vertical Heat Tunnel System
This vertical heat tunnel system included three high temperature heat tunnels and was designed to dry a water based coating on narrow fabrics. It replaced an existing system by increasing line speeds 6X. Heated make-up air delivered to the bottom of the unit and exhaust hoods at the top were provided.
Access to the system interior was provided by pneumatic retraction. A temperature feedback process control system is also illustrated.
Horizontal Heat Tunnel System
Annealing or stress relieving a cast nylon film was the application for this horizontal high temperature heat tunnel system. The design included pneumatic access for product threading and structural steel support of the unit, as well as the control enclosure. The entire system was factory assembled, tested and portable.
Tire Cord Heat Conditioner
This standard heat tunnel was designed to heat condition tire cord. It processed 17 light denier ends running side by side on 1/4” centers.
