UV System low energy UV

Low Energy UV curing for sheetfed printing

The LE UV system has now made it possible for all commercial printers to benefit from the advantages of energy-minimised drying - at low investment and operating costs! Just one dryer is required in the machine for all standard commercial printers. For perfecting presses, a dryer is additionally used before the perfecting device.

Immediate drying of the printing ink

The sheet can be passed on immediately for further processing, there is no interim storage required for drying the printed sheets
There is no need for powder to be used
Good level of abrasion resistance, no protective coating required
There is no additional IR drying necessary, thus saving energy costs

Brilliant print results

Thanks to maximum process reliability and immediate drying, the highest of quality standards are met

Low level of ink setting
Bleed ink area possible
Superb finishing options

Less space required for drying

The innovative LE UV system takes up less space in the printing room than both conventional drying systems and traditional UV systems:

No delivery extension necessary for drying
Space required for switch cabinet, heat exchanger and exhaust-air unit < 2 m²
No interim storage needed for printed sheets

Ozone-free operation

The use of special lamps facilitates an ozone-free operation.

Benefits

URS cold mirror reflector technology

The URS cold light reflectors only reflect the short-wave light and allow the heat radiation to pass through to a cooled aluminum profile. The geometry and reflective properties of the URS reflectors are precisely matched to the requirements of the respective production process.

Lamp output

The reduced number of lamps (typically 1 lamp with 200 W/Cm lamp power) saves energy and therefore leads to considerable cost savings. When using adapted reactive ink systems, there are no restrictions in terms of drying or productivity.

Ozone-free operation

The use of special lamps facilitates an ozone-free operation.

Electronic power supply device ELC

The electronic lamp control system (ELC) continuously adjusts the lamp output to the printing speed of the press. Due to its high electrical efficiency, the ELC is characterized by low energy consumption. Operating voltage fluctuations of ±10% have no effect on the lamp output.

Constant temperature level

The integrated air cooling guarantees smooth operation of the lamp. The ingenious water cooling of the shutter, reflectors and housing ensures that the heat generated is effectively dissipated from the press. A water/water heat exchanger is standard. An air/water heat exchanger is also available as an option.

Information

Position in the printing press

For all standard commercial printers, just one dryer is required after the last printing unit.

For perfecting presses, a dryer is additionally used before the perfecting device.
