UV Control Systems
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.

Excimer Systems
GEW’s ExciRay lamp systems utilise dielectric barrier discharge (DBD) lamps to produce quasi-monochromatic vacuum ultraviolet radiation, typically at 172nm. This radiation is commonly used for mattification of surface coatings, modification of surface tension for improved adhesion or surface cleaning for semiconductor and medical industries.
DoseGuard Laboratory Unit
GEW’s DoseGuard Laboratory Unit is the perfect quality control system for any pressroom with multiple GEW UV-equipped machines. It offers a fast, simple and accurate method to measure the UV output of any GEW UV Arc or LED cassette across its entire width under standard conditions. The system can analyse any GEW cassette manufactured since 2000.
How does the DoseGuard Laboratory Unit work?
The DoseGuard sensor is mounted inside the Lab Unit, below the lamp mounting position. When a cassette is inserted, the Lab Unit will run the lamp at the selected power level and scan the entire length of the lamp. Irradiance in mW/cm2 is measured and UV dose at any speed is calculated for easy comparison of expected curing performance. Warning levels can be set to easily identify non-conforming cassettes and data can be simply exported via USB in Excel format.
What’s included?
All units include a cassette housing, a power supply, a heatsink, a fan and a touchscreen for operation.
UV cassettes are provided by the customer from the production systems to be analysed.
An ozone filter can be included as an optional extra, enabling the Lab Unit to be used stand-alone without the need for any extraction ducting.
The benefits for your press room
- Reduces rejects through early detection of under‑curing, enabling timely corrective action.
- Strengthens GMP compliance through reliable, auditable quality control reporting.
- Improves maintenance decisions through early detection of UV lamp ageing.
- Detects and clarifies the impact of reflector and quartz window conditions on curing performance.
UV Lamp Lab Unit
The UV lamp lab unit utilises a 150mm wide stainless steel conveyor belt to drive samples under the UV lamp at variable speeds up to 70m/min.
The E2C UV lamp contains an ozone-free bulb to prevent the need for duct extraction and an integrated fan controls the lamp at a constant 80W/cm.
A robust, bench-top curing unit incorporating simple feeder/catcher trays, it is a perfect, cost-effective tool for laboratory, press proofing and even low volume production.
