Advantages		Disdvantages
Produce vast amount of UV photons Generat full range UV light (1 00-400nm)		High energy consumption High maintaining cost No flexible arrangement Environmental concern of mercury and ozone Long time to warm up and cool down Shutter normally required Limited use to heat-sentitive material

 

Advantages		Disdvantages
Energy saving minimal 70% to comparing arc lamp Very low maintaining cost during life time No IR radiation and very few visible light Suitable for heat-sensitive material Compact and resistant to vibration Instant on/off Longer life time up to 25,000 hours Uniform radiation across the exposure area No ozone produced No mercury		Limited spectrum range Thermal management for LEOs Ink or coating formula need to be adjusted to match LED spectrum

 

Why UV LED Is Now Qualified to Printing Industry (1)
UV LED single die power output has increased over 200X since 2003.

New developed packing technology now can reach over 30W/cm2 on receiving surface, which could satisfy most of
the applications.

UV LED Curing System Is Undoubtedly The Trend
UV LED curing system market is keeping over 50% annual increasing recent years.

In China market, over 50% new sold narrow web presses are installed UV LED curing system in year
2017, and over 95% will be installed in year 2020.

Brief Introduction of CoolUV

No.1 Brand of China Narrow Web UV LED Curing Market

CoolUV Technology Started the R&D on UV LED curing since 2009
For 8 years continue Research on UV LED curing, we’ve built our own knowledge system on how to produce a powerful and stable curing system.

Is More Professional on Die-level Optical Design
Ink or coating curing involves complex chemical reaction which requires UV radiant intensity, peak intensity, spectrum range match, exposure duration.

CoolUV considers these factors
from very beginning of the design- dies packing and micro optical design.

CoolUV Technology Started the R&D on UV LED Curing Since 2009
For 10 years continue Research on UV LED curing, we’ve built our own knowledge system on the 4 key-technology:
dies packing and optical design, driving design, thermal management. and friendly integration and application support.

Excellent Thermal Management

LEDs produce vast heat during working, dies work at high temperature will cause the great life reduction.

So to maintain a as lower as possible working temperature is very important.
Transfer and dissipate the heat quickly and efficiently is a very challenging work.

CoolUV start the work from dies packing.

Advanced Controller And Control System
CoolUV developed advanced controller as a standard module for different application, which provides rich functions, interfaces.

Lamp Has Excellent Life Time
By excellent thermal management, packing technology and driving technology, CoolUV lamp’s life time therefore extends to over 25,000 hours.

Products For Different Application
CoolUV also has developed various products for printing, coating, adhesive and specific industry customization

CoolUV Products Lines

PowerCure and SuperCure Series Are Widely Applied on Narrow Web Press
CoolUV lamps are now applied to almost all printing methods like offset, flexo, cameo, silkscreen, inkjet, gravure printing.

In China market, more than 200 presses have been installed with our UV LED curing system since 2014.

And among these systems over 60% lamps are on narrow web presses.

PowerCure and SuperCure Technical Details

Benefits By Using UV LED Curing System
UV LED curing is really a green environmental friendly technology.

By cutting significant carbon emission, zero-mercury to handling, almost no changing parts, long using life, the users and our planet benefit very much from this technology.

Using Cost Comparing With Arc UV Lamp

Inks: A Very Important Factor

Case Study 1: Using cost for 8 printing stations offset press (13″ web)

Case Study 2: Using cost for 10 printing stations Flexo press (17″ web)

Conclusion Of Case Study:
