Nvidia MCS85xx director systems liquid-to-liquid CDU - The water-to-water heat exchanger is called a Cooling Distribution Unit (CDU)
The water in the primary and secondary loops are not mixed within the CDU. Each one of the loops has its own requirements that should be met to allow proper system performance.
The water in the secondary loop complies with very stringent quality requirements. It is used to cool the electronic components directly.
The water in the primary loop is the facility's water. It circulates through the CDU heat exchanger only. The quality of the water in this loop should be monitored and maintained by the customer but the quality standards for this loop in overall are more relaxed compared to those of secondary loop.

Redundant PSU (1+1)
Redundant pump (2+1)
Internal 50 micron filter
Drain/Fill port without internal pump
Pressure release valve
External IF: ModBus TCP via std RJ45 connector
Max power dissipation: 500W
Full set of telemetry
