About this item

Electricity Cost Reduction-In L-CURE There is substantial power saving upto 80% over HUV, LE and Mercury UV system
Heat Reduction- Unlike H-UV or traditional mercury lamps, LEDs (Light Emitting diodes) emit very little infrared heat i.e 60 C. This avoids common heat-related issues in Sheet-Fed printing such as high pile temperatures, curling of heat sensitive stock materials and loss of moisture in paper.
Increase Up Time- LED's instant on/off switching means that there are no Warm-up and Cool-down cycle that are required in conventional UV system. Machine Up time is increase because it is instant on/off and there is no moving parts like: Shutters, Reflectors.
Less Number of Lamp Required- LED drying needs fewer lamps as compared to Mercury UV resulted power saving as well as less modification in offset press.
Longer Consumable Life- Average life of LED diodes is 20000hrs where as in case of Mercury UV it is 1000hrs.
Low Maintenance Required.
LED elimination of Ozone smell and Hazards.
Substrate moisture Retention.

Description

For Sheet-fed Offset Presses
For Flexible Packaging Industries
For Narrow to Medium Web Printing Presses
UV Curing technology was introduced to the printing world in late 80’s and proved to be ground breaking with never before print solutions and
applications. Now substrates thought impossible to print upon could be printed and with ease, predictability and at good speeds. High deposits
of inks/ coatings were suddenly possible with instant drying properties of UV technology. In short the revolutionary technology opened a whole
new world of printing solutions, innovation and creativity.
For over 3 decades mercury medium pressure lamps were primary source of UV radiation. For such a long time inspite of being cumbersome
and highly power inefficient these system ruled the world of UV equipment as no other alternative technology could come even close to
Medium pressure Mercury Lamps. LED’s as a source of UV radiation were there as an idea since a long time but it is only now that LED’s have
become a reality overcoming many technical hiccups over last many years with development and advancements in LED manufacturing
technologies accompanied with development in compatible inks/ coatings. LED’s have now become a reality unleashing another revolution in
lifeline of UV printing world with advantages of massively energy efficient, low heat, long life LED UV curing solutions. So come lets explore the
magical world of UV printing now with LED UV curing with us.
Alpna introducing on a New Generation of Upgradable UV LEDs and Brings You
to a New Era of Printing and Industrial Curing solutions.

General Features
Core of System
Power Consumption
UV Source Life Time
Heat Generated by Lamp
Radiation Type Emitted
Environment and Health
Maintenance Required
MERCURY UV
Silicon Diode LED
Low normally quantified in hundreds of watts/hr
More than 20000 working hrs
60 C max, measured in lamp emitting window
Pure UV
No mercury and other dangerous substances
Glass window cleaning only
GLED UVs
Fragile cylindrical quartz bulbs
High, normally quantifies thousand of watts/hr
Varying from 500 to 2000 working hours. It depends on the condition of use and the environment
Greater than 150 C on lamp window. The bulb can reach 900 after a few minutes of operating
Rays emitted UV-A+UV-B+UV-C+IR
Contains mercury and metal halide potentially dangerous for the environment
Frequent ordinary maintenance: glass cleaning, periodic replacement of UV bulb, replacing reflectors, cleaning filters
ADVANTAGES OF LED
High resistance to vibration and shock
Power consumption is 60% less: thus investment cost is recovers by the user in a short time
No UV emitter to replace, No technical maintenance
Lower heat implies lower heat built up in presses
Improved safety for the operator. It does not emit Dangerous UV-C radiation
It is not necessary to dispose emitters as special waste
Almost absent maintenance cost and production downtime
