AETEK UV Curing System for Web Printing - UltraPak

The UltraPak arc lamp offers the option of true "cool" UV curing of inks and coatings on heat-sensitive materials for almost all makes of narrow web presses, including Gallus, Aquaflex, Webtron, Mark Andy, Nilpeter, and Didde.

The UltraPak system utilizes an optional dichroic reflector and quartz IR filter in combination with superior heat-management features to permit efficient curing of inks or coatings without the use of chill rolls.

The UltraPak system uses a unique 0.75" (19 mm)-diameter bulb on its 400 W/in (160 W/cm) mercury lamp system for a more focused exposure area and efficient cure. Measured against equivalent 600 W/in (240 W/cm) lamp systems with traditional 1.1" (28 mm)-diameter bulbs, an increased cure speed of up to 33 percent can be achieved, running, for example, a 7-10-micron black screen ink. Gallium or metal additive lamps are also available to provide the most efficient spectral output for certain UV processes and heavy ink laydowns.

The UltraPak UV curing system provides outstanding performance and customer interface features. The system design allows ganging of lamp systems to enable rapid reconfiguration and installation on multiple-lamp presses. Interface with the operator and with the press is made through PLC-based controls and an operator display/keypad or optional multi-lamp monitoring touch-screen.

The modular cassette design is fully interchangeable from print station to print station, providing the flexibility to cure at different locations throughout the press. The UltraPakcan be supplied with new in-line presses through the OEM or as a retrofit on existing machines to allow partial or full UV capability.

Specifications:

Curing Applications
UV inks, varnishes, laminating adhesives and coatings on paper, films and foils and on a wide range of heat-sensitive materials.

Lamp Module
The lamp cassette module removes easily for quick access and service. Lamp power, control and pneumatics are provided through a single, quickly removed connecter.

Size
Lamps are available for press widths of 7", 10", 13", 16", 18" & 20" (18, 25, 33, 41, 46 and 50 cm).

Power Supply Selection
Electronic, variable power and tri-level constant wattage ballast power supplies are available, depending on application.

Cooling
The cooling system is modular with a small dedicated exhaust blower linked to each lamp module and driven through the power supply. The system uses thermocouple(s) to run the variable frequency drive (VFD) and to provide quieter operation during standby or low power settings, using less energy to maintain the lamp in standby mode.

Controls and Operator Interface
Keypad controls or optional touch-screen provide for easy changes to the lamp operating and set-up parameters and facilitate the operator-to-equipment interface.

Hot Mirror and Cold Reflector Option
An advanced heat-management package allows the lamp system to be operated with IR-sensitive substrates. This package combines a dichroic filter and advanced heat-management techniques to enable the lamp system to cure filmic substrates without chill rolls.

Safety and Reliability
All systems are fully interlocked and designed to ensure the highest level of operator safety and years of reliable operation. All are fully assembled and tested before leaving the factory.

Telephone Modem Diagnostics
All Aetek UV multi-lamp modules (two or more UV curing modules) are equipped with a telephone modem to permit immediate access to the UV system controls for remote diagnosis and troubleshooting. It is offered as an economically priced option on smaller systems.

Training Program
Aetek UV Systems offers a full in-house or on-site customer training program to familiarize customers with safe operation of the equipment.

24-Hour Hotline Customer Support
Aetek UV Systems provides a 24-hour customer support hotline with fully trained personnel to talk through problems and dispatch field service technicians worldwide, as needed.
