Components of the system
RHINO electronic power supplies (housed in distribution cabinet on multi-lamp systems)
Touch screen operator interface
Autodamper air regulator(s)
Rigid ducting manifold (or multi-lamp systems)
All necessary interconnecting cables (not pictured)
Mechanical integration with the press
Each UV station is hinged to allow easy access to the under-bed sheet supports and belts. The units are easily lifted to 20° inclination and held in the raised position. A large air-cooled heatsink protects the conveyor from excessive heat build up.
Typical UV installation on a metal decorating press (click to zoom):
The single-lamp interdeck units are mounted over the belt section of the press infeed between each print unit.
An air cooled under-bed heatsink protects the conveyor from excessive heat build-up.
The single-lamp under-sheet unit is mounted after the coating station to cure any excess varnish that may have seeped over the sheet edge.
A hinging air-cooled heatsink shields the operator from heat build-up and stray light escaping from the unit.
The set-stack and / or final cure units are mounted over the belt section at the end of the press. Both are multi-lamp units and the number of lamps is determined by the machine configuration. These units are also fitted with large under-bed heatsinks to prevent heat build-up in the conveyor.
Extraction fan and vertical ducting with integral autodamper to withdraw the UV lamp heat and ozone.
Electrical integration behind the press
RHINO power supplies with integrated mains distribution for a 4-colour press with coater.
Cabinets can be grouped together or positioned along the length of the press.
UV Lamphead benefits
NUVA2 UV System is safe for the widest range of heat-sensitive materials
Versatile and controllable, with no heat transfer to the machine or substrate at stand-by through the use of actively air cooled shutter technology.
- Optically tuned reflectors maximise the lamps’ curing effect
- Substrate overheating is reduced
- Air cooling is now as effective as water cooling
- Supports the fastest printing speeds
- Highest dose + highest intensity = maximum curing
- Engineered for fastest, easiest lamp changes
- Lamp’s ceramic end design prevents breakages during lamp change (patent pending)
- All replaceable components are plug-and-play for easiest maintenance
- Patented active airflow path minimises air consumption and contamination of lamp and reflectors: less cleaning is required to maintain curing performance
Energy performance measurement
The RHINO control automatically logs energy use and displays it on screen at the touch of a button, showing kWh consumption in operation, at idle and % production uptime.
Proactive downtime avoidance
Our Embedded Service Package regularly sends system performance data to GEW for analysis. A system health report is generated, highlighting any out-of-tolerance parameters requiring maintenance attention before a fault can develop.
Working at peak performance
The Event Log continually records system use and operating parameters. The Log can be checked to ensure the system is working at peak efficiency, avoiding energy waste and unplanned downtime.
Multilingual instructions are easily accessible on every screen together with a library of tutorials and videos, troubleshooting and maintaining the system.
Military-grade electronic design protects the UV system from damage caused by incorrect voltage, short-to-ground, dropped phases, mains spikes and lightning strikes. In the event of a serious mains disruption, the system powers down in a safe mode.
Survives the harshest environments
RHINO is designed to run in harsh conditions at ambient temperatures of up to 40°C. The system is also unaffected by dust, ink mist and other atmospheric contaminants.
Minimal footprint RHINO Rack
A compact cabinet that houses up to 6 RHINO power supplies and provides perfect cooling, atmospheric protection and mains power distribution. Cabinets are stackable 2-high, enabling 12 power supplies to fit into a 115 x 65 cm floor area. Power supplies slide into rack and connect quickly, enabling more lamps to be easily added to the system in future.
Lowest operating costs
With intelligent power management the current draw from each mains phase is balanced and harmonic distortion is minimised, reducing the energy demand registered by your electricity meter. Reducing harmonics in operation maximises existing mains capacity because energy is not lost as heat in cabling and transformers.
