Stampa la paginaOZONE
Standard DYMAX bulbs (UVA type) generate an insignificant amount of UVC and therefore essentially no ozone.
Some UV light-curing systems, like those used to cure UV inks, emit primarily "shortwave" (UVB and UVC)
energy. Upon exposure to UVC light (specifically <240 nm), oxygen molecules (O
) split into oxygen atoms (O)
2
and recombine with O
to create ozone O
. The current, long-term ozone concentration limit recommended by

ACGIH, NIOSH, and OSHA is 0.1 ppm (0.2mg/m
).
BRIGHT, VISIBLE LIGHT
The bright, visible light emitted by some UV light-curing systems can be objectionable to some workers and can
cause eyestrain. Tinted eye protection and/or opaque/tinted shielding can be utilized to address this concern.
SUMMARY
UV light sources can be more "worker friendly" than many commonly accepted industrial processes, provided the
potential concerns are addressed. Contact your DYMAX representative for information regarding the proper use
of DYMAX UV light-curing systems.
GENERAL
®
The BlueWave
50 is a high-intensity, UV light-curing Spot Lamp used for the curing of adhesives, coatings, and
potting materials. It emits an UV light from a Lightguide. This guide can be hand-held for complete mobility,
clamped into position for repetitive operations, or in automated equipment.
The unit consists of an anodized aluminum Housing, containing a Transformer Power Supply, Circuit Protection,
Bulb/Reflector Assembly, Internal Light Filter for extended Lightguide life, Thermostatically-Controlled Cooling
Fans, Lightguide Mount, Bulb Status Indicator Light, non-resettable Hour Meter, and Shutter system. The
Lightguide is separate and plugs into the Lightguide Holder.
WARNING:
Engage the Lightguide in the Lightguide Mount before the light is turned on and remove the
Lightguide from the Lightguide Mount ONLY AFTER the light is turned off to avoid the possibility of exposure to
the UV light. Lightly tighten the Setscrew for safety.
AVERTISSEMENT:
Engager le guide de lumière dans le biseau avant la lumière est allumer, et enlève le guide
de lumière de le biseau SEULEMENT après la lumière est fermer pour éviter la possiblité d'exposition à la
lumière. Reserrer doucement la vis pour sécurité,
The Bulb Status Indicator Light above the Lightguide Mount lights when the Bulb is operating. If the Bulb
extinguishes due to a momentary power failure, the unit must be turned off, allowed to cool, and then turned back
on again to re-ignite the Bulb.
A Cooling Fan is provided to keep the Bulb Housing and internal components of the Power Supply at the optimum
operating temperature. The Cooling Fan must not be covered or otherwise blocked. Fan Filters should be
changed or cleaned frequently to prevent blockage and reduced ventilation airflow. The Power Supply operates
on line voltages of 230V
50Hz or 115V
60Hz (factory set).

The UV source is a 50-Watt short-arc mercury-vapor Bulb mounted in a Reflector and pre-focused to provide
optimum light output. The unit is rated for continuous operation.
