1800W Water Cooled LED UV Curing System CG-CT5-30050-1800W 300x50mm 180 Chips for High Speed Label Printing

1800W Water Cooled LED UV Curing System CG-CT5-30050-1800W

The CG-CT5-30050-1800W is a linear water cooled UV LED curing head built for continuous high speed production lines. It runs 6 LED boards with 30 chips per board — 180 chips at 10W each — delivering 1800W of optical output across a 300 x 50 mm emitting window while holding chip density and 18W/cm² irradiance steady across the full window.

Key Features

• Wider pass, same intensity: the curing window is extended to 300 mm by adding LED boards rather than spacing chips further apart, so irradiance stays at 18W/cm² from the first chip row to the last with no cold strip at the window ends.
• Higher line speed: 1800W of optical output covers a wider web or a two-up layout in a single pass, so press speed no longer has to be traded for cure.
• Stepless dimming: 0% to 100% stepless output control lets the head match ink chemistry, substrate and line speed without mechanical shutters.
• Instant on and off: no warm-up and no shutter delay, ready for indexing, short runs and on-demand curing.
• Low temperature cold light: heat is carried away by the water circuit, protecting heat sensitive film, thin foil and PE substrates.
• Mercury free: no ozone, no VOC discharge and no lamp disposal cost.
• Long service life: 20,000 hour LED lifespan with a 2 year warranty on the complete system including chiller and power supply.

Technical Specifications

Typical Applications

• High speed flexo, offset and digital printing ink curing
• Label and packaging film printing and varnish curing
• Coating, lacquer and surface finish curing
• Adhesive and laminating curing for film, tape and labels
• Electronics conformal coating and component bonding
• 3C, medical device and packaging decoration lines

Working Notes

The lamp head must be connected to a matched water chiller. Recommended coolant flow is 6-10 L/min with inlet water temperature below 25°C. Keep the quartz lens clean and hold the emitting window 30-50 mm from the substrate to obtain the rated UV intensity. When upgrading from a 200 mm head, confirm that the chiller capacity and power supply are rated for 1800W.

Customization

Window length is built in 50 mm increments per LED board, so 250 mm, 350 mm and 400 mm versions are available on request. 395 nm and 385 nm are normally used for printing inks, while 365 nm is preferred for adhesives and deep cure. OEM configuration, voltage and labeling are available for volume orders.
