New Compact Infra-Red Print Dryer from Heraeus Noblelight

Infradry Compact

The Infradry Compact is a new high performance infra-red (IR) drying system for a wide range of water-based inks and coatings from Heraeus Noblelight.

The drying system combines high power density infra-red radiation with controlled air flow and extraction to provide effective and efficient drying.

The radiation to dry inks, varnish or colours is provided by powerful twin tube IR emitters. These can be of wavelengths from near infrared to medium wave, depending on the specific application. NIR emitters operate at a surface temperature of 2600°C for very rapid, intense drying, while medium wave emitters have a surface temperature of 900°C and offer the most efficient mechanism for the removal of water from a product surface.

To remove the evaporated moisture from the surface of the printed product, the Infradry Compact features a specially developed air management, which feeds an homogeneous distributed air flow into the IR-module’s drying area, either by internal or external air supply. This inlet-air is pre-heated by the IR emitters, absorbs the evaporated moisture and removes it from the drying zone. This prevents saturation of the atmosphere inside the drying zone and also precludes leakage of hot air to surrounding, heat-sensitive machine components.

With its very high-power density and its extremely efficient reflectors, which concentrate the IR onto the substrate surface, the new Infradry Compact offers very high drying performance. Its compact, modular design and plug-and-play installation and it is configurable with a wide range of interfaces. Lamp replacement is quick and easy through a slide-in drawer. An integral pyrometer and stepless power regulation ensure precise control of drying operations.
