UVEXS - SAC Product Information

small area uv curing with optional chamber

The Small Area Curing Subsystems (SAC's) small area, high intensity UV curing unit fills the need for a compact subsystem for localized exposure of UV curable materials. The SAC features a scaled-down cabinet, lamps and lamp house to facilitate production line integration where space is limited. A complete SAC package includes a power supply module with adjustable lamp power levels and a forced air-cooled lamp house module.

Features

Short lamp sizes in a compact, modular design, for integration ease. Mercury vapor UV lamp with power levels at 150-200-300 watts per inch. Various packages for IR removal. Aluminum extrusion design. Internal pneumatic shutter and digital exposure timer are optional.

Benefits

Complete surface and depth curing. Allows UV where space is a premium. Durable design exceeds rigorous industrial usage. Low temperature curing for heat sensitive materials. UV process means increased efficiency. Consumes 80% less energy than IR process. Reduced environmental impact (no solvents).

Description

As part of a series of modular lamp systems, UVEXS offers the Small Area Curing system for efficient and affordable UV exposure of compact assemblies and substrates. The Model SAC requires minimal space for integration. Available features equal those of the larger UVEXS Model OCU Series including variable power levels up to 300 watts per inch. The high intensity, full spectrum UV energy (200-400 nm) rapidly cures adhesives, inks, coatings and potting materials, in thick section and without surface tack. The complete system consists of a power supply module and lamp house module with interconnect cables.

A variety of options are available for controlling the exposure, filtering IR energy and lamp length.

Select Lamp Length

2'' (5 cm), 4'' (10 cm), 6'' (15 cm)

Standard or metal halide lamps are available.

Lamp House Module

The lamp house module contains a single medium pressure mercury vapor arc lamp. Internal cooling fans are standard on all lamp sizes with exhaust connections provided. Lift out lamp assembly eases maintenance procedures.

Ultraviolet Lamp

Medium pressure mercury vapor arc lamp available in 2, 4, and 6 inch lengths. Power levels are 150, 200 and 300 watts per inch standard, with 450 watts per inch optional. UVEXS lamps are warranted to operate for a minimum of l,000 hours.

Operating Controls

Power ON and OFF switches

Lamp LO/MED/HI selector

Power level indicator

Lamp operation hour meter

Optional shutter control package includes additional controls as follows: timer ON/OFF switch, digital timer setting (1-59 seconds), and manual OPEN switch.

Power Supply Module

Regulated ballast type power supply mounted in a separate forced air-cooled cabinet. Input requirements: 208/240 VAC, 60 Hz, single phase; option is available for 220 VAC, 50 Hz operation. Current varies with lamp size and power level; consult UVEXS for specifics.

Reflector Configurations

'R1' ConfigurationFull output, unfiltered

'R2' Configuration50% IR, filtered

'R3' Configuration95% IR, filtered

Ordering Information

When ordering, specify lamp length, reflector configuration (R1, R2 or R3), lamp power levels, and desired options (shutter, "Ready" signal, variable reactor, etc.) Spare lamp recommended.

Installation Concerns

It is recommended to connect the air exhaust to a facility exhaust system; air flow rates vary with lamp size. Installed lamp house may require shielding around curing area to protect operators; consult UVEXS for design considerations or custom shielding packages.

Optional Features

Shutter	Exposure control is available with an internally mounted knife blade shutter, compatible with all reflector configurations. Includes an internal pneumatic cylinder to drive the shutter plate, adjustable OPEN/CLOSE rate, and high temperature bearings on stainless steel shaft to assure reliable operation. Input requirement: 70-90 psi clean dry air or nitrogen.
Shutter Control Package	Includes internal pneumatic switch and digital timer (1-59 seconds) for OPEN/CLOSE functions. An interface connector allows for remote PLC operation. Manual OPEN switch allows test operation for Q.C.
Variable Reactor	Provides continuously variable power control for the UV lamp. With the system set on HIGH power the variable control range is 150-300 watts per inch. Monitor/control circuit available for PLC operation of lamp power level.
'Ready' Signal Interface	Optional control card allows power level monitoring for process interlock during lamp warm up. Additional circuits available for allowing PLC control of system operating functions.
