UV LED UniJet AHD-Series
The UniJet AHD modules are compact water-cooled UV LED modules delivering exceptional curing performance.
Water-cooled UV LED modules are high-intensity curing systems where heat generated by the LEDs is removed through a closed-loop liquid cooling circuit. The water (or glycol mix) circulates through a heat exchanger or chiller, keeping LED junction temperatures low and ensuring stable light output and long lifetime — critical in industrial printing processes like inkjet, flexographic, and screen printing.

General Features
- High irradiance of 24 W/cm² (at WD = 5 mm) – ensures powerful, efficient final curing
- Up to 210 % higher UV dosage than the standard A-Series, supporting a wider ink range and higher printing speeds
- Compact design – smaller and lighter than conventional UV lamp system
- Modular flexibility – optional units can expand the window width up to 80 mm
- Split irradiation – enables targeted curing zones for process optimization
- Adjustable output (10 – 100 %) for precise control
- Replaceable UV LED boards – simplifies maintenance and reduces downtime
Unique Product Features
- Higher Power Density: Water cooling allows compact designs with higher UV intensity, enabling faster curing at higher printing speeds
- Thermal Stability: Consistent cooling ensures uniform UV output, maintaining color and gloss consistency across wide webs or large print formats
- Quiet & Clean Operation: No fans mean less airborne contamination and lower noise — ideal for clean production environments
- Longer LED Lifetime: Reduced thermal stress extends LED life and minimizes maintenance
Applications
- High-speed inkjet and flexographic printing (wide-web, label, packaging lines)
- Industrial coating and 3D printing where high UV output is needed
- Environments with limited airflow or strict cleanliness standards
