When a Heidelberg DryStar-type LED-UV curing module needs replacement, many printing plants first search by press model or system name. This is useful for initial reference, but it is not enough for accurate replacement.
An LED-UV curing module is an integrated curing component. It may include segmented LED curing windows, aluminum housing, water-cooling connectors, cable connections, mounting holes, and control-related interfaces. If one of these details does not match the original module, the replacement may not install correctly or may not perform properly in the curing section.
For this reason, YFR recommends confirming the replacement by original module photo, press model, wavelength, power output, cooling method, connector type, cable direction, mounting structure, and installation position.
For customers who need a custom replacement solution, YFR supplies LED-UV Replacement Lamp Module for Heidelberg DryStar-Type Curing Systems for selected printing press UV curing applications.
To confirm a suitable LED-UV replacement module, the supplier needs enough information to check both curing performance and mechanical installation.
Please provide the Heidelberg press model, press series, installation position, and printing application.
Common printing applications include UV ink curing, LED-UV varnish curing, coating curing, packaging printing, and commercial printing.
The original module information is more important than the press model alone. Please provide clear photos of the original LED-UV module from different angles.
Useful photos include:
Front view
Back view
Side view
Connector area
Cable direction
Water-cooling connection
Mounting hole position
Original label or code, if available
If there is no drawing, these photos can help YFR make an initial replacement evaluation before quotation.
The key curing parameters should also be confirmed before production.
Important information includes wavelength, power output, cooling method, module length, working width, ink or varnish type, and curing requirement.
If the original system data is available, it should be sent together with the module photos.
For many LED-UV printing applications, 395 nm UVA is commonly used for LED-UV ink and varnish curing. However, wavelength should not be assumed without confirmation.
Possible wavelength options may include 365 nm, 385 nm, or 395 nm, depending on the ink system, varnish type, curing material, and original module specification.
If the wavelength does not match the ink or varnish system, curing quality may be affected even when the module physically fits the machine.
Power output should be checked according to the original LED-UV module and printing process. Some printing UV curing systems use adjustable power output in the range of 30–44 W/cm², but the final configuration should be confirmed according to the original module and production requirement.
Higher power is not always automatically better. The correct power output depends on ink formulation, substrate, printing speed, curing distance, cooling design, and machine integration.
Many LED-UV curing modules for printing presses use a water-cooled structure to support stable thermal control and reduce unwanted heat transfer to the printed substrate.
When replacing a water-cooled LED-UV module, the cooling pipe connection, water inlet and outlet position, connector size, sealing structure, and installation clearance should be checked carefully.
An incorrect cooling connection can create installation problems and may affect module stability.
For related UV curing product options, you can also check the UV Lamps category, which covers UV lamps, UV mercury lamps, UV exposure lamps, and LED-UV replacement modules for printing and industrial curing systems.
The replacement module must match the curing width and installation space of the original system.
Buyers should measure the total module length, effective working width, mounting hole distance, and available machine space.
Photos should include the full module body and close-up views of both ends. If there is a label or serial marking, include a clear close-up photo.
Connector type and cable direction are critical for installation.
Even when the wavelength and power output are correct, a mismatched connector or cable exit direction can prevent smooth installation.
Before quotation, please confirm whether the cable exits from the left side, right side, rear side, or top side of the module. Also provide photos of the original connector and cable routing inside the machine.
LED-UV replacement modules must align with the existing mounting structure. This includes mounting hole location, bracket position, module thickness, installation angle, and available space around the curing section.
For retrofit or non-standard systems, a drawing is helpful. If no drawing is available, clear photos from multiple angles can support initial replacement evaluation.
YFR can support replacement evaluation for selected Heidelberg printing press LED-UV curing applications, including systems used on Speedmaster-type presses.
Common press references may include:
Speedmaster XL Series: XL106, XL105, XL75
Speedmaster CD Series: CD102, CD74
Speedmaster SM Series: SM74, SM52
Speedmaster CX Series: CX104, CX102, CX75
Important note: The press model can help with initial evaluation, but final compatibility should not be judged by press model alone. The original module photo, label, wavelength, power output, cooling method, connector structure, cable direction, mounting dimensions, and installation position should be confirmed before quotation.
A structured confirmation process helps reduce replacement risk and makes it easier for both the buyer and supplier to confirm whether the module can be manufactured to match the existing curing system.
Send the press model, original module photo, label, or drawing.
If the original module has a label, code, or specification plate, include a clear close-up photo.
Confirm the wavelength, power output, module length, working width, cooling method, connector type, and cable direction.
This step is important because LED-UV curing performance depends on both optical output and system integration.
Confirm the mounting holes, water-cooling connection, control interface, and installation position.
If the module is installed in a tight machine space, installation clearance should also be checked.
YFR reviews whether a suitable replacement LED-UV module can be manufactured or supplied according to the original structure and technical requirement.
After specification approval, sample production or batch production can be arranged.
For repeat orders, confirmed specifications can be recorded as the production reference for future replacement supply.
The press model is useful, but it does not confirm the full module structure.
Different production years, retrofit systems, printing widths, and curing configurations may use different LED-UV module designs.
UV curing performance depends strongly on the match between wavelength and ink or varnish system.
Before ordering, confirm whether the original module is 365 nm, 385 nm, 395 nm, or another specification.
Water-cooled modules require accurate connection matching.
Cooling pipe direction, port size, water inlet and outlet position, and installation clearance should be checked before production.
Two presses from the same series may have different curing configurations depending on machine setup, retrofit history, curing position, and application requirement.
One front-view photo is usually not enough.
For accurate evaluation, send front, back, side, connector, cable, water-cooling connection, label, and installation position photos.
Traditional UV mercury lamp replacement usually focuses on total length, arc length, rated power, lamp diameter, cap type, and connector structure.
LED-UV module replacement requires additional checks, including cooling method, segmented module structure, cable direction, mounting holes, and control interface.
If your printing press uses both IR drying and UV curing sections, YFR can help evaluate different replacement products, including UV lamps, LED-UV modules, and infrared drying lamps.
For infrared drying sections in printing presses, you can also view FMW IR Emitter for Printing Drying and Coating Curing. For Heidelberg infrared drying lamp replacement, see Heidelberg Replacement Lamps.
Replacement may be needed when the curing result becomes unstable, UV output drops, the module suffers cooling or connection issues, or the original module is no longer economical to repair.
Common signs include:
Incomplete UV ink or varnish curing
Uneven gloss or curing across the sheet width
Frequent overheating alarms
Cooling connection problems
Physical damage to the module housing or lens area
Difficulty sourcing original replacement components
Before replacing the module, confirm whether the problem comes from the LED-UV module, power supply, cooling system, control system, ink compatibility, or machine settings.
YFR supports custom lamp and module replacement projects for printing, drying, curing, and industrial process equipment.
For printing press applications, YFR can help customers evaluate both infrared drying lamp replacement and UV / LED-UV curing module replacement. This is useful for printing plants, service teams, and spare parts distributors that need support for different drying and curing sections in one equipment system.
For LED-UV replacement projects, our team checks the original module structure, wavelength, cooling method, connector, cable direction, mounting design, and installation requirement before quotation.
This helps reduce replacement risk and confirms whether the module can be manufactured to match the existing curing system.
YFR is suitable for customers who need custom replacement support, repeat supply, and technical confirmation before production.
