Lytron heat exchanger / water cooling system. Exchanges heat from DI water circuit to facility water. Siemens p/n 5845388 Rev D - Lytron p/n LCS7096G2. Used. See photos: there are some minor marks where water has dripped in the interior of the case - we do not know whether this was due to a minor leak, or if some water simply spilled when the unit was disconnected.
