At InPrint 2016 in Milan GEW will display its proven range of arc lamp and LED UV curing systems for printing and coating applications available in widths from 10cm up to 2.5m with a single lamp. GEW UV systems are robust, versatile, fully air-cooled systems for applications in the inkjet and industrial printing industries.
NUVA2 UV system up to 2.5m wide
GEW’s NUVA2 arc lamp UV system is engineered for efficiency and lowest maintenance. Active air-cooling and optically tuned reflectors maximise the lamps’ curing effect while at the same time reducing heat radiation onto the substrate. In any UV curing installation the NUVA2 and the associated RHINO power supply achieve accelerated production speeds, increased uptime and energy savings of up to 50%, backed up with the security of a 5-year warranty unique in the industry.
LA1 air-cooled LED UV system
The LA1, GEW’s patented air-cooled LED UV curing lamphead, is the most powerful of its kind. Special consideration was given to the enhanced airflow design to ensure effective heat dissipation at high power levels of up to 22 W/cm2 depending on wavelength. The LA1 is built around the same proven modular cassette-based design known from other GEW ranges and is fully compatible as an upgrade for existing lamp-based ArcLED systems. The LA1 is able to perform without the need for external chillers and the additional maintenance required by comparable water-cooled LED systems while enjoying the benefits of the reliability, long-term consistent output and extended life cycles of LED technology.
In-line UV monitor
Multipoint in-line UV dose control is an essential enhancement to any new UV arc lamp system. It allows comprehensive continuous monitoring of the UV output during the curing process and acts as a built-in UV intensity meter. The UV monitor measures the actual intensity across the full width of the lamp with great precision before the wrong dose could have an impact on production. Low intensity which would not adequately cure is thus avoided, as is insufficient output from a degraded lamp. As a result unnecessary downtime is eliminated and production efficiency is accordingly improved.
