Take a closer look at GEW’s new precision control system, OxyGuard, which uses state-of-the-art technology to rapidly achieve and maintain the optimal curing atmosphere for low odour, low migration production, siliconisation and other high performance curing applications.
Ambient oxygen reduces the effectiveness of UV curing in many inks and coatings. The OxyGuard system can be used to overcome this, by controlling oxygen at the point of curing, exactly where the ink or coating is exposed to UV light. Inert gas is used to purge the curing chamber of oxygen and maintain a target oxygen level during production runs.
OxyGuard features closed loop control, which automatically maintains this oxygen level to a customer set point (measured in parts per million), and ensures this set point is not exceeded. The OxyGuard system adapts the input of inert gas accordingly, regardless of machine running speed. Throughout the process, gas consumption is optimised for maximum efficiency.
OxyGuard can be retrofitted on existing nitrogen systems and is compatible with all GEW curing lamps, whether UV Arc or LED. It is fully customisable to any number of configurations, making it suitable for a broad range of demanding applications… including coating and converting, silicone release and low migration work, excimer mattification and wood finishing.
