Preferably the Arcam EBM system should be connected to a central cooling system.
If a central cooling system is unavailable, Arcam EBM offer stand-alone water chillers. See Pre-
Installation Guide for detailed requirements on the external chiller.

An internal cooling system provides cooling for dif-
ferent components of the EBM machine.
It is located between the cabinets and is accessible
via the outer access panel or the inner access
panel.
The cooling system is divided into one external and
one internal circuit, connected via a liquid-to-liquid
heat exchanger.
The closed internal circuit automatically regulates
the temperature keeping media at 2 2 5 5 º º C C . .
External cooling media should be between
1 1 0 0 t t o o 2 2 0 0 º º C C . .
