UV Dual
HIGH QUALITY UV COOL CURING SYSTEM
Powerful UV curing unit, specially designed to generate high curing power, yet keeping the substrate always cool. It is ideal for all kinds of applications, from the graphic to the industrial ones, as well as for the P.C.B. industry. Available in 2 lamp configuration, it is ready for the fitting of the third lamp.
UV DUAL is particularly recommended whenever high production levels and low temperature are required.
Main features
Structure
Made from electro-welded hardened tubular steel.
Its accurate design has resulted in an extremely compact unit which includes the curing section and all the components necessary for the heat exchange, for an even distribution of the air flow and for the ozone extraction.
Thanks to its construction features, the DUAL can be easily connected to hot air dryers, thus performing the function of cooling section when using solvent-based inks.
Inlet section and conveyor belt
PTFE coated fibre-glass mesh, with adjustable speed from 3,7 to 37 mt/min.
The inlet section includes the optical belt centring device as well as the automatic belt stretching system. A belt extension can be added for special applications.
Lamps and reflectors
The elliptic-shaped reflectors provide optimal ray focusing and consequently excellent curing.
The UV lamps feature independent selectable output power (80 – 100 – 120 W/cm) for remarkable energy saving.
Swivelling lamp reflectors for easy lamp cleaning and inspection purposes.
Cooling and ventilation systems
A special ventilation system ensures the cooling of the reflectors and of the quartz filters, provides the vacuum under the conveyor belt and the ozone extraction.
An additional fan feeds the blowers placed over the conveyor belt with cooled air by means of a heat exchanger.
These two systems of air recirculation allow keeping the temperature inside the dryer under complete control, granting dimensional stability even to the most heat sensitive substrates.
The heat exchanger can be connected either to the factory water network or to a refrigeration unit for a better efficiency of the cooling system.
Adjustments and controls
The control panel is located on the separate electrical cabinet and includes all the safety devices and the controls of all the functions, such as :
- Belt speed
- Number of working lamps and related output power
- List of alarms and troubleshooting
In case of failure the lamps are automatically switched off.
