The document discusses low energy UV curing systems. It describes the existing hCP lamphead design and a future EN2a lamphead design that uses optimized reflectors and lamps for higher intensity curing with lower energy consumption. A new e-Brick power supply is also presented that uses high-frequency output for more efficient curing and lower power usage. Finally, the document mentions a new touch screen controller for intuitive system monitoring and control.

2. LOW ENERGY UV CURING
1. Existing Design – The hCP Lamphead

3. hCP Semi Focussed Lamp Head
• Water cooled reflector with semi focussed design.
Dichroic coated inserts (replaceable).
• Uses ozone free iron doped lamps.
• Quartz plate seals lamp head
(helps take heat away from substrate).
• Both air and water cooling.
• Quartz plate slides out to allow lamp changing.

2. Future Design – The EN2a Lamphead

8. EN2a …Lower Energy Consumption
• Optimised reflector and lamp design.
• Higher dose and significantly higher peak intensity.
• Water cooled case and reflector for cool running.
• EN2 @ 100w/cm = VCP @ 160W/cm.
• Uses ozone free iron doped lamps.

3. Highly Efficient Power – The e-Brick

17. e-Brick Power Supplies…
… for superior energy efficiency

18. High-frequency square-wave output
Increased UV energy
available to cure
What does this mean?
Less input energy is required to give the same cure
FOR LOWER POWER CONSUMPTION
OR... The press speed can be increased
FOR BETTER PRODUCTIVITY

19. Low stand-by power
Measured standby power (as percentage of full power)
Traditional PSU 30-40%
It is common practice to leave
Electronic e-Brick 18% lampheads running on standby
between print runs
LOW STANDBY POWER
=
LOWER ENERGY BILLS

4. System Control – The Touch Screen HMI

22. Touch Screen Controller
• Touch sensitive colour display.
• Intuitive icon based menus.
• Clear display of system status
and control parameters.
• On-screen commissioning and
diagnostics.
• Convenient hotkey buttons.
