UV curing system OmniCure® AC4 series

UV LEDfor coatingair-cooled

Product description
OmniCure® AC4 Series air‑cooled UV LED small‑area curing systems (models AC450, AC450P, AC475, AC475P) combine high‑output LEDs and custom optics to deliver peak irradiance above 8 W/cm2 with excellent longitudinal uniformity across 50–75 mm cure areas. A patented per‑module addressing process maintains consistent output across the full LED array, enabling uniform exposure of larger or multiple parts for higher throughput and lower operating costs.

System control and reliability
The AC4 Series provides precise control of UV irradiance and exposure time to ensure the correct energy dose at the selected wavelength for repeatable curing. Integrated PLC control, intelligent monitoring, I/O ports and remote operation capabilities support automated production lines and minimise downtime.

Features

• Peak irradiance > 8 W/cm2 for fast curing of adhesives, coatings and inks
• Custom front‑end optics for high peak irradiance at longer working distances
• Patented individual LED module addressing for superior longitudinal uniformity
• Available in 365 nm and 395 nm to match adhesives, coatings, inks and substrates
• Air‑cooled design: simple integration without external chillers, ozone extraction or special venting
• I/O and PLC integration for automation and remote control
• Highly efficient LED modules: lower power consumption compared to arc lamps
• Compact footprint: easy integration into workstations or production cells
• Typical lifetime > 20,000 hours, with LED warranty of 2 years or 10,000 service hours
• Narrow LED wavelength: lower temperature curing and improved yields versus arc lamps
