Introduction

This manual covers the Nordson CoolWave 2 610 Ultraviolet Microwave

Curing System. It provides safety, installation, operation, and

troubleshooting and repair information for the system and its components.

What is UV Curing?

Ultraviolet curing is achieved by a chemical reaction in special inks and

coatings when intense UV energy is focused on them. Curing efficiency

depends on UV power, coating weight, operation speed, type of substrates,

material chemistry, and other factors.

The UV Curing System

The system is designed to cure UV inks, adhesives, and coatings for

numerous industrial applications. The system consists of an individual 10-in.

lamphead, a corresponding variable output system controller, a RF detector,

and appropriate cables. Additional lampheads can be lined up end-to-end to

form longer curing widths.

How Does it Work?

Inside the lamphead, a microwave generator (magnetron) operating at 2400

to 2500 MHz excites a 10-inch medium pressure UV bulb. Microwave

energy from a magnetron is directed by a wave guide to the UV bulb. A

screen located at the opening of the cavity allows the UV light emitted by

the bulb to pass through while containing the microwave radiation.

The wavelength of the emitted UV light is between 220 and

470 nanometers. Power output is 600 watts per inch.

Light shielding is required to protect the operator and meet safety criteria. If

shielding cannot fully contain the UV light, then the operator should be

provided with protective equipment (refer to Safety in this manual).
