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

CG-CT5-30050-1800W Water Cooled LED UV Curing System 300x50mm

The CG-CT5 series is a linear water-cooled UV LED curing head for continuous high-speed production. This 300 x 50 mm version runs 6 LED boards, 30 chips per board, 180 chips in total at 10W each, giving 1800W of optical output over a wider curing window while keeping the same chip density and the same 18W/cm² irradiance as the 1200W model.

Technical Specifications

Why Choose The 300mm Version

• Wider pass, same intensity: the window grows from 200 mm to 300 mm by adding LED boards, not by spacing chips further apart, so irradiance stays at 18W/cm² across the full 300 mm.
• 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.
• Uniform cure edge to edge: six boards on a common water-cooled baseplate keep output balanced from the first chip row to the last, with no cold strip at the window ends.
• Instant on/off: no warm-up and no shutter delay, ready for indexing and short runs.
• Low temperature: cold light output protects heat-sensitive film, thin foil and PE substrates.
• Mercury-free: no ozone, no VOC discharge and no lamp disposal cost.
• 20,000 hour lamp life with 2 year warranty on the complete system.

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 keep the emitting window 30-50 mm from the substrate to obtain the rated UV intensity. When upgrading from a 200 mm head, check that the chiller capacity and power supply are rated for 1800W.

FAQ

Q: How is the 1800W rated?
A: 6 LED boards x 30 chips per board = 180 chips, at 10W per chip, giving 1800W total.

Q: Is the UV intensity higher than the 1200W model?
A: No. Chip density and drive current are unchanged, so irradiance stays at 18W/cm². The extra power is used to cover a wider 300 mm window, not to raise intensity.

Q: Can the window be made in another length?
A: Yes. Length is built in 50 mm increments per LED board, so 250 mm, 350 mm and 400 mm versions are available on request.

Q: What wavelength should I choose?
A: 395nm and 385nm are normally used for printing inks, while 365nm is preferred for adhesives and deep cure.

Q: What is the lead time?
A: 10-15 working days for standard configurations.
