UV curing system DRF series

microwavein-linefor coating

Overview
The DRF Series are UV curing systems engineered for optical fiber and cable production. Models include DRF F6 (6-inch) and DRF F10T (10-inch) lamp modules. The systems use microwave-driven electrodeless lamps integrated with a secondary elliptical reflector to deliver focused, high-intensity UV irradiance for rapid, uniform curing of buffer coatings, coloring inks and ribbon matrix polymers.

Specifications

• Electrodeless bulb options with multiple spectral outputs
• Lamp modules: 6-inch (F6) and 10-inch (F10T) irradiators; selectable power levels
• Matched power supply for each lamp module
• Light shield and secondary elliptical reflector housing (F6 or F10T), sealed quartz tube enclosure, optional nitrogen fittings
• Optional blowers for matched cooling air

Features

• Microwave-powered, electrodeless lamp for spectral consistency and fast startup
• Patented secondary reflector system yielding high UV irradiance per watt
• Modular lamp housings and power supplies for straightforward maintenance and replacement
• Power supplies can be grouped for simplified electrical control and prewired interconnections
• Interchangeable bulbs to match bulb energy to photochemical response
• Optional easy-align lamp mounting system for repeatable alignment during replacement

Applications

• Optical fiber buffer coating curing
• Coloring inks for fiber and cable
• Ribbon matrix polymer curing
• Cable marking and small-diameter cable processes

Additional information
The DRF Series is optimized for continuous, high-speed UV curing in optical fiber manufacture. Electrodeless lamps reach maximum output within seconds and operate continuously with stable spectral output. The optical fiber passes through a sealed quartz tube located at the secondary focal point of the elliptical reflector to ensure full-surface exposure and minimal stray radiation.

Power & configurations
Configurations support modules from compact ~1.8 kW units (e.g., F300S) up to high-power 6 kW systems (e.g., F600, LightHammer® 10H Mark II / LightHammer 10 Mark III). Some systems offer selectable or variable output ranges (example: 35%–100%). Multi‑lamp arrangements allow per-lamp switching to adapt curing energy to line speed or coating thickness.

Installation & cooling
The DRF Series uses an air-cooled push–pull airflow system with positive and negative-pressure blowers. The sealed quartz tube is isolated with a Teflon® gasket; housings include end plates for mounting fittings. Lamps may be mounted in any orientation; optional alignment kits and tool‑free observation options (F10T2) aid maintenance and process monitoring.

Notes and safety
Lamps contain mercury. Handle and dispose in accordance with applicable local, state and federal regulations.
