WATER COOLING D620i
The water chiller and compressed air must be connected to the laser. To
avoid damage to the laser tube, only clean compressed air free of oil, to
Class 1.7.2 of ISO8573 should be used. The compressed air is used to
prevent too high humidity values inside the laser module. Therefore to
prevent water condensation inside the laser module.
Adjust the pressure of the compressed air between 2.5 and 3 bar. This
equals an air flow rate of 20 litres per minute. The water chiller is operated
by the controller via the X28 connector. Also switching on and off is done
via this connection.
See the water chiller manual for more details. Coolant may be ordered from
Domino. The coolant has to be exchanged at least every two years.
Note: Contact Domino before disconnecting the silencer or
connecting a hose to the air outlet 2 at the laser. If two hoses are
used for the compressed air outlet these have to be placed in
different positions for safety reasons.
