LOW ENERGY UV CURING
1. Existing Design – The hCP Lamphead
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
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
e-Brick Power Supplies…
… for superior energy efficiency
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
Low stand-by power
Measured standby power (as percentage of full power)
Traditional PSU 30-40%
Electronic e-Brick 18%
LOW STANDBY POWER=
LOWER ENERGY BILLS
It is common practice to leave lampheads running on standby between print runs

4. System Control – The Touch Screen HMI
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.
