Figure 2: The illustrated schematic provides a generic representation of the typical primary hydronic loop distribution to rack-mounted coolant distribution units (CDUs). It is advisable that the piping material and connection accessories be chosen according to the CDU manufacturer's requirements for each project. Additional engineering efforts may be necessary to determine how to circulate the water and control the temperature and that may require changing the piping arrangements per project.
