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.
