Laser cluster and DMD are cooled by a liquid thermal system. This system is built up by single circuits,
consisting of fan, radiator and pump. There are two such single systems cooling the laser cluster and one
cooling the DMD. A thermal conductive gasket is used between the pump and the cluster ensuring good
thermal connection.
Laser cluster pumps Follow instructions as described above in chapter “Remove the Liquid cooling
