COOLING THE i-TECH 15 SCAN HEAD
The i-Tech 15 is an extremely fast scan head with relatively large and fast
mirrors. This allows for superior performance in applications where a large
marking field is required.
In order to ensure reliable operation of the scan head at high temperatures
and/or high duty cycles the scan head may need additional cooling. To
avoid interruptions in the manufacturing processes we strongly recommend
a careful evaluation of the given conditions. The table on the next page
provides information about when to use additional compressed air cooling
in typical marking applications.
The Mark Duty Cycle (MDC) may be calculated using this formula:
• Duty Cycle (%) = (mark time (ms) x product rate (products/s)/ 10
• Example e.g. for a message of 50ms mark time printing 4 prints per
second. The duty cycle is 50 x 4 / 10 = 20% in this example.
Operating pressure is 4 bar.
To cool the scan head, connect the compressed air to the inlet and the
silencers to the air outlets.
