Overview

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 mirror reflectors only reflect the shortwave light, allowing the thermal radiation to pass to a cooled aluminium profile. The geometry and reflection properties of the URS reflectors are designed to match exactly the requirements of each production process.

Lamp output

The reduced number of lamps (typically 1 lamp with 200 W/Cm lamp output) saves energy and thus leads to significantl cost savings. When using adapted reactive colour 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) adjusts the lamp output steplessly coupled to the printing speed of the press. Due to the high electrical efficiency the ELC features a low energy consumption. Operating voltage fluctuations of ±10% do not affect the lamp output.

Constant temperature level

The integrated air cooling guarantees a smooth operation of the lamp. The sophisticated water-cooling of the shutter, the reflectors and the housing ensures that the produced heat is effectively removed from the press. A water/water heat exchanger is standard. Optionally an air/water exchanger is available.

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.
