NUVA2 HP
Fully air cooled, extreme high power lamp design perfect for web & industrial applications.
NUVA2 HP is the same NUVA2 cassette in a narrower format − the extra cooling available allows running up to 240W/cm, with maximum power decreasing as lamp length increases. Fully air-cooled, NUVA2 HP is available with a wide range of customisation options and is perfect for final cure inkjet applications (with iron-doped lamps) or high-speed web machines.
GEW’s patented reflectors are actively cooled to ensure that heat transfer to the substrate is minimised, whilst delivering the highest UV intensity and dose available. The quick-change cassette design ensures fast lamp changes with only 1 hex key tool required and all replaceable components are plug and play for easiest maintenance.

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.

Substrate Cooling
Controlling temperature is critical for many applications. GEW’s array of cooling options ensures even the most powerful UV systems do not damage substrates.
The UV curing process is energy-intensive and causes both direct and indirect heating of the target substrate, which in the majority of cases needs to be controlled. For safety reasons, some form of barrier behind the target substrate to shield off and dissipate stray radiation from the lamp is essential for protecting the machine and its operators. The three most common methods of substrate cooling that meet both of these requirements are:
Air cooled heatsinks
Water cooled heatsinks
Water cooled chill rollers
Where roll material is being processed, the most common solution for this is an extruded aluminium heatsink plate. GEW have a very neat solution for this which is integral to the UV lamphead and can be either air or water cooled, depending on the application. For the majority of processes this method is very effective, unless very heat sensitive materials are being used.

UV Power Systems
All GEW RHINO power supplies are rack mounted, able to run arc and LED lamps, and internet connected with 24/7 continuous online monitoring.
GEW UV arc and LED systems are powered by the proprietary RHINO and RLT power supplies. Available in a range of sizes up to 27kW, they are custom designed and manufactured by GEW, exclusively to power our UV systems. They meet the highest international safety standards (including ETL listing for all RHINO units), are monitored over the internet 24/7 and can be purchased with up to a 5-year warranty − unparalleled in the industry.
Every power supply is equipped with GEW’s ArcLED technology, enabling both UV arc and LED to be powered interchangeably by the same unit. Every RHINO & RLT system in the field is ready to run LED − only the LED lamp and chiller are required to make this change.
