Ultra Violet curing is a fast developing drying method in printing industry. It has a wide application in Varnish Coating and Printing with UV inks on various substrates like Papers, Boards, Wood, Glass, Plastic etc., It gives High gloss finish matt finish and it gives highly chemical and water resistive surface. UV consumes less power and Eco friendly because of no volatile emissions. It dries the ink or varnish instantly which leads to less dot gain and good adherence on the plastics substrates like PP, BOPP, PVC etc.,
We deliver total uv solution for your industry. The below mentioned are the product for your business needs.

( Mercury Vapour or Metal Halide Lamps )

Mercury Vapour Lamps or Metal Halide UV Lamps are used in the conventional UV system. The mercury vapour lamp is the medium pressure vapour lamps commonly used in curing applications. Metal Halide lamps are also used now to avoid mercury. These are all made up of Quartz tubes with ceramic holders.
The Lamp wattage will vary as

• 200watts per inch,
• 300watts per inch,
• 400watts per inch,

The lamp generate UV radiationfrom 280nm to 410nm (UVA, UVB, UVC) along with heat radiation.
The reflector assemblyare used to concentrate the UV light on the substrates with different focal length. The reflector may be Semi-circular or Parabolic cross sections.
The reflectors are mainly

• Anodized Aluminium sheets
• Dichoric coated aluminium sheets
• Dichoric plated quartz glasses

The Lamp reflectors is cooled by Air or Water.
Automatic shutters are used in Interdeck UV system to protect the lamp radiation exposure to the machine and substrate at the idle hours of the machine.

LED is Light Emitting Diode which generates high intense UV radiation utilizing less power. This is the new development which replaces the conventional Mercury Vapour and Metal Halide lamps which are more hazardous.
LED is having UV-A and UV-C type wavelengths. The UV-A lamps are 365nm to 410nm.
LED UV intensity varies from 6W to 30W per sq.cm.
LED generates Cool UV light at the front end and heat at the back end. So it requires less cooling. High Quality Lens are used to concentrate UV radiation on the substrate.
LED can be instantly switch ON/OFF which gives good control over the LED operation and saves the power and machine conditions.

Why LED UV chosen against Conventional UV?

LED UV	Conventional UV
Less Power Consumption (20% of conventional UV)	High Power consumption
Instant ON/OFF Power Varied with Simple system	Continuous Lighting intensity can be varied with complex power control system
Less Heat generation	Very high temperature generated leads to Fire accidents
Less Cooling required	Complex cooling required
Normal Voltage Application varies 200V to 400V	High Voltage application varies from 800V to 2000V
Very compact	Complex System
Modular Switching Possible Every 50mm can be ON/OFF	No Modular switching possible
Life : 20000 hours	Life : 1000 hours
