Fusion Light Hammer 6

The Fusion Light Hammer® 6 brings all of the benefits of microwave-powered UV curing to a six-inch (150 mm) system. Operating in the power class of 500 watts/inch(200 watts/cm), the Fusion Light Hammer® 6 features two easy-to-service modular components: the microwave-powered irradiator and the solid-state power supply. At the heart of the microwave technology is the electrodeless bulb mounted in an elliptical reflector for focusing an intense strip of UV energy 53 mm (2.1 inches) below the face of the lamp.

Features & Benefits



Electrodeless Technology The microwave-powered lamp and its electrodeless bulb technology have proven themselves over time and in hundreds of demanding applications. These long life bulbs are known for their stable performance, high intensity and low maintenance operation.
Popular Bulb Spectra Available The standard bulb spectra are available: “H” spectral distribution is suited for clear-coats and varnishes; the “D” spectral distribution is popular and proven for inks and thick coatings or adhesives; and the “V” distribution is effective for UV curing white basecoats, through laminating materials and in other specialty applications.
Fast UV Curing from High Peak Irradiance and Low Infrared The small diameter bulb combined with the elliptical reflector provides high peak of UV irradiance for high-speed cure. The small diameter bulb also reduces infrared emission resulting in lower surface temperatures of the substrate, thus eliminating the need for complicated heat removal methods.
Higher Efficiency from the Solid-State Power Supply Each lamp system has its own microprocessor based, modular power supply. The high voltage circuit inside the power supply consists of a solid-state, switching engine. This reduces ownership costs because it extends the life of the magnetron and the bulb by supplying a constant source of power to the lamp (Process patent US 6908586B2.) The solid-state electronics run cooler and more efficiently – saving money on power, reducing environmental noise and space requirements. Power output from 35% to 100% can easily be controlled from the front panel or remotely through contact closure from a PLC (programmable logic controller). This variable power feature permits matching of the lamp output to the machine/line speed or to the ink/coating demands. A sophisticated microprocessor control system allows multiple lamp systems to be interconnected and controlled individually or as a group. And there is no loss of illumination at the juncture of two lamps so that multiple irradiators can be joined end-to-end or in a continuous array for large processes.
Electronic Shutter Integration of the lamp into processes, which require a rapid on/off cycle, is now realized without the use of a bulky, mechanical shutter. The Fusion Light Hammer® 6 can repeatedly cycle from high power to very low power over a few seconds. Shutters are not required, owing to the fast response of the lamp to control demand. This cycling operates under reduced air-cooling as a function of duty cycle.
Improved Cure The ultimate benefit of the Fusion Light Hammer® 6 is the achievement of higher degrees of conversion than is typically achieved with high ripple (AC) powered UV sources (Process patent US 6908586B2.)

Cross-wise Adapter Plate Allows I6 irradiator to be mounted in a light shield for I300M; positions irradiator in a 90-degree orientation to the I300M position.
External End Reflectors Flat plate UV reflectors, constructed of light gauge aluminum with R500 UV reflective surface; designed to fit in a light shield to provide increased radiant uniformity over full length of bulb.
(Remote) Pressure Blower Vane-type blower with air intake filter housing, to provide filtered air to the irradiator with the proper flow and pressure. A number of power options and configurations are available.
Conveyors Belt and roller conveyors, web, cable and fiber systems are available. Other special product handling systems can be quoted on request.

Irradiator modules placed end-to-end effectively form a continuous lamp of any length, which are multiples of 168 mm (6.6 in.). Some specifications will increase proportionally with the number of lamps in a system.
