Cooling water
MetalJet D2+ systems are supplied with a water cooling solution which is fully integrated into the control
software. In order to avoid damage to the system due to overheating, the water flow and water reservoir fill
level are continuously monitored. Full software integration of the water cooling system is a requirement for
MetalJet D2+ systems.
Note:
Customer supplied water cooling solutions can only be supported if flow rate and fill level can be
communicated to the control software by either RS232 or USB. In addition, the water temperature has to be
compatible with the melting point of the alloy used. Contact Excillum for further information about water
chiller requirements if an external water cooling solution is preferred or required.
MetalJet D2+ systems are currently delivered with a standalone water-to-air heat exchanger. Excillum
