E4C
E4C offers the highest power available from the GEW range, to support the most demanding UV curing applications and the fastest printing speeds.
E4C offers the highest power available from the GEW range, to support the most demanding UV curing applications and the fastest printing speeds on web or sheetfed machines. It performs to the harshest cure test procedures and is suitable for low migration applications.
E4C has optically tuned reflectors to maximise curing power and operates quietly, with minimal air requirements. Water flow monitoring technology ensures water flow at all times, and the E4C’s water-cooled reflectors support the highest UV power whilst limiting heat transfer to the substrate, making it safe for a broad range of heat-sensitive materials.

Inert Gas Curing
Oxygen inhibits the UV curing mechanism. GEW’s inert gas chambers efficiently remove oxygen and improve the curing process. Find out more below:
Under normal atmospheric conditions, oxygen reacts with photoinitiators in the ink after they are exposed to UV light. This renders some of them inactive and limits the extent of polymerisation that can occur. The coating is then poorly cured or the process is forced to run much slower. This is where inert gas curing comes into play.
Curing under an inert atmosphere eliminates oxygen and significantly increases the rate and extent of cross-linking. Curing speeds are greatly improved, migration of harmful materials is reduced and the finished product odour is better.

UV Control Systems
Simple touchscreen controls backed up by an internet-connected remote monitoring service − GEW RHINO control is unparalleled in the industry.
GEW UV systems are controlled by a combination of user commands and settings (entered on a modern industrial touchscreen), as well as machine signals which are either hardwired or electronically communicated to the GEW RHINO power units. GEW’s proprietary RHINO software is able to handle a vast array of common industrial control interfaces from simple relay logic to web-based APIs.
The HMI itself has a simple user interface for operating all key parameters on up to 16 lamps simultaneously, customised for each specific machine configuration. Optional accessories such as GEW’s UV monitoring or inert gas chambers are also controlled through the same user interface. It can be mounted freestanding in any location on or around the press or bevel mounted for seamless integration in machine panels.
