Overview

THERMOcure – hot air & IR drying system for industrial coating processes

Efficient drying with infrared and hot air

THERMOcure is a powerful, modular hot air and infrared drying system that has been specially developed for industrial applications. Through the targeted combination of IR radiation and convective hot air, THERMOcure enables fast, uniform and energy-efficient drying of water- or solvent-based inks, varnishes and coatings – in sheetfed offset as well as narrow web and label rotary printing.

The system is ideal for pre-drying, intermediate drying or final drying and can be flexibly integrated into existing production lines – both as a stand-alone solution and in combination with our UV or LED UV curing systems.

THERMOcure: Drying with warm air and infrared radiation

Functional principle: infrared meets warm air

Graphic_Wave lenghts UV and IR

The exceptional performance of THERMOcure is based on the synergistic interaction of infrared radiation and warm air:

  • Infrared radiation (IR) heats the coating film directly and accelerates the evaporation of water or solvents.
  • Warm air supports the removal of the evaporated components and ensures even temperature distribution.
  • The result is a significantly reduced drying time with controlled energy input.

Compared to pure convection drying, THERMOcure works more efficiently, faster and with greater process stability, especially at high production speeds.

Your advantages with THERMOcure

  • High drying performance thanks to combined IR and hot air technology
  • Reduced process times and increased productivity
  • Energy-efficient drying through targeted heat input
  • Modular, compact design for easy integration
  • Individually configurable in terms of width, power and temperature
  • High process reliability even with sensitive substrates
  • Can be combined with UV and LED UV systems

THERMOcure thus offers a future-proof solution for demanding industrial drying processes.

Information

Application: Sheetfed

In sheetfed offset printing, THERMOcure is used as a fully pre-assembled cassette. The system is designed for different machine and space conditions and is available in various standard widths, which can be individually adapted as required.

The modular design allows for practical configuration:
  • Flexible choice between IR and carbon emitters per cassette
  • Optional configuration without emitters, e.g. for pure hot air applications
  • Cable clamps accessible from below for quick and easy lamp replacement
  • Adjustment of equipment depending on width and process requirements
THERMOcure is particularly suitable in the sheetfed sector for:
  • Pre- and intermediate drying of conventional inks
  • Stabilisation of the printing process with high ink applications
  • Preparation for subsequent UV or LED UV curing
     
THERMOcure: Drying with warm air and infrared radiation

Application: Label printing

For narrow web and label rotary printing machines, THERMOcure offers specially tailored IR-based drying concepts that are designed to meet the requirements of water-based ink systems.

IR emitters (infrared and near-infrared for drying water-based ink systems)

The IR emitter operates in the near-infrared range and is used to dry water-based inks and coatings in rotary label printing machines. The energy is applied directly to the wet coating film, which means that drying begins immediately after the respective printing unit. The system is process-stable at high web speeds and is particularly suitable for dense ink sequences and demanding substrate materials. The emitter can be exchanged as a replacement cassette for UV or LED modules, thus allowing flexible production configurations.

Features:

  • Area of application: water-based inks and varnishes on films and papers
  • Wavelength: near infrared (above approx. 800 nm)
  • Start of drying: immediately after ink application
  • Module concept: interchangeable cassette IR ↔ UV ↔ LED
  • Application: label and narrow web rotary printing

The combination of near-infrared IR emitters and warm air combines direct heating of the paint or lacquer film with efficient removal of the humid process atmosphere. While the film is quickly heated by IR, the warm air loosens the moist boundary layer on the surface and removes it via a mixture of laminar flow and specifically generated turbulence. This reduces the surface partial pressure, accelerates evaporation and compensates for adiabatic cooling effects through IR input. Compared to separately controlled IR and hot air stages, this results in a model increase in drying performance of around 30–50%, depending on layer thickness, air volume and temperature window. The system has been tested for label rotary printing machines up to 150 m/min and offers a wide process window with high production output.

Features:

  • Area of application: water-based inks and varnishes
  • Web speed: tested up to 150 m/min
  • Process control: adjustable IR power, coordinated hot air volume/temperature
  • Flow control: combination of laminar + turbulent boundary layer separation
  • Increased drying reliability with high ink applications and dense ink sequences
  • Application: label and narrow web rotary printing
