DYMAX UV flood lamps use a medium pressure arc bulb as a source of radiant energy. This bulb requires a few minutes to warm up after ignition before it reaches a steady state and after being turned off, needs a few minutes to cool before
being able to ignite again. Turning the bulb off-and-on negatively affects the lifetime of the bulb. With a DYMAX shutter installed the UV flood lamp may stay on continuously. Objects needing curing may be loaded and unloaded from
underneath the shutter when it is shut, without exposing operators to ultraviolet light. In addition, precise control of curing times can be achieved by timed shutter operation.
The shutter can be operated in two modes: timed and manual. In the timed mode, the shutter opens by pressing a switch on the front panel, or by activating the remote
switch (i.e. foot pedal switch). The shutter will remain open for the length of time defined by the timer, freeing the operator to perform other tasks during the curing cycle. In the manual mode, pressing the button on the
front panel or remote switch (i.e. foot pedal) can activate the shutter, and the screen will remain open for as long as the button or pedal is depressed. The ZIP™ Shutter is compatible with DYMAX 1200-EC,
2000-EC and 5000-EC UV flood lamp curing systems. |
