Tunele Suszące UV/IR DUAL

UV/IR drying tunnels

Keller's DUAL UV/IR drying tunnels combine two print curing technologies in one device: UV radiation and IR heating. They're a solution for businesses that work with a variety of inks, varnishes, materials, and printing technologies, yet require a stable, efficient, and predictable drying or curing process.

In practice, this means greater production flexibility. A single tunnel can handle processes requiring UV curing, IR drying, or a combination of both. UV IR drying tunnels They are particularly useful where production series, types of details or printing technological requirements change.

Key features of DUAL Keller tunnels

DUAL UV/IR drying tunnels can include:

• combination of UV and IR technologies in one device,
• smooth regulation of belt speed,
• IR heating power adjustment,
• regulation of the power of UV lamps,
• UV lamp cooling system,
• thermal insulation of heating sections,
• temperature stabilization and uniformity,
• notification and warning system,
• transport adapted to the type of detail,
• configuration for an existing production line.

UV IR drying tunnels for demanding printing processes

The DUAL tunnel is designed for companies that don't want to limit themselves to a single ink curing method. The UV module is responsible for the rapid curing of inks and varnishes that react to ultraviolet radiation. The IR module supports processes requiring controlled heating, solvent evaporation, or thermal stabilization of the coating.

This combination allows for better adjustment of operating parameters to specific materials, inks, and details. This is particularly important in screen printing and pad printing, where different substrates may require different print fixation methods. Plastics, glass, metal, foils, painted elements, and unusually shaped details all behave differently.

IR UV drying tunnels with adjustable operating parameters

IR UV drying tunnels Keller is equipped with systems that allow for the adjustment of key process parameters. The operator can adjust parameters such as belt speed, exposure time, IR heating power, and UV light intensity. This allows the device to be tailored to the specific paint, surface, and desired end result.

Depending on the design, the tunnel can be equipped with a notification and warning system, UV lamp cooling, thermal insulation, temperature stabilization, and solutions that facilitate uniform part flow through the drying zone. The goal is not only to preserve the print but also to ensure repeatability of the process during serial production.

This solution can reduce the number of changeovers, facilitate work organization and make better use of available space in the hall.

A tunnel matched to the detail, paint and machinery

As a manufacturer of UV IR drying tunnels We design equipment to meet specific customer requirements. We select the belt width and length, clearance height, transport mode, UV section power, IR heating parameters, and control method. We can also consider compatibility with existing machinery, including screen printing machines, pad printing machines, and other production stations.

A key element of the design is the way the workpiece is guided. Flat elements require different solutions, 3D products require different ones, and workpieces that need to be rotated or guided in a specific position require different solutions. Therefore, the DUAL tunnel is not a universal device in the simple sense, but rather a solution designed to truly fit the production process.

Greater flexibility in the print fixation process

The DUAL UV/IR tunnel is a worthwhile choice when production requires working with various printing technologies, inks, and materials. This device allows for faster response to changes in orders, better control of drying parameters, and reduced risk of insufficient print curing.

Keller provides design, construction, commissioning, and technical support for the selection of tunnel operating parameters. This ensures that the client receives a solution tailored not only to current needs but also to future production process development.
