SunBelt 25 Product Summary

The Uvitron SunBelt 25 is a wide-width, high-power light-curing conveyor system designed for high volume production or laboratory processing of large parts. The system features a high-output arc lamp that is powered by a compact, programmable, electronic power regulating ballast.

The UV conveyor has a quiet variable-speed motor with a velocity regulating drive that keeps conveyor belt speeds constant for varying loads. It offers a long, enclosed UV curing tunnel with entrance / exit light guards for maximum light shielding.

The belt-to-lamp height can be easily adjusted for improved compatibility with varying part sizes.

Additional Details

High output lamp head with forced air cooling: The lamp head contains a 25” arc length, 10,000W metal halide type lamp, which emits focused UVA, UVB or visible light from its elliptical reflector. Dual integrated cooling blowers ensure long lamp life.

Lamp power regulation: The UV curing system’s electronic switch-mode ballast maintains constant lamp power regardless of variations in AC line input or lamp voltages. This regulation provides for repeatable curing times and longer lamp life.

Adjustable lamp height: Curing chamber handles and locator pins allow for easy adjustment of lamp height from 2–11”, which provides perfectly repeatable settings of lamp head to belt distance for various part sizes.

Adjustable Lamp Height

Full UV shielding: The UV curing conveyor light chamber is totally enclosed, shielding the operator and others from any UV light. The curing chamber entrance and exit are protected by adjustable height light guards that minimize any light leakage.

Convenient front-mounted controls and indicator panel: The control panel features lamp enable and emergency-stop switches, AC power, lamp ignited, lamp ready and alarm indicators, as well as a lamp hour meter and USB programming connector.

Regulated belt speed controller: A variable frequency drive with digital speed readout is used to adjust and regulate UV conveyor belt speeds up to 58’ per minute, allowing for repeatable product exposure time and curing dose.


Exhaust blowers and port: The UV curing chamber has three blowers mounted below the belt for evacuating heat and any product vapors. The outlets of these blowers are ducted to a rear-mounted port for venting to facility exhaust systems.


Adjustable mounting feet: The system has four adjustable mounting feet for setting system height and allowing leveling on irregular floor surfaces.

In-feed product guides: Dual angled guides at the entrance side of the conveyor’s 33” wide belt ensure that products being cured are directed into the 25” lamp cure zone. For larger products that only require center curing, the guides can be removed.

In-feed Product Guides

Lamp ballast programming software: The system includes graphical interface software for monitoring curing system performance, diagnosing system alarms and programming lamp output power.
