Common measurement points include CDU secondary-side supply and return lines, coolant pump discharge ports, heat exchangers, and filter inlets/outlets. Gauge pressure measurement is primarily used to monitor supply/return lines and pump operating status, while differential pressure measurement helps assess flow resistance variations across heat exchangers, filters, and fluid circuits. FRD's current CDU portfolio focuses on heat exchanger/filter differential pressure, secondary-side supply/return gauge pressure, and pump dynamic pressure.

Wetted materials cannot be determined solely by the term 'liquid cooling.' One must first confirm the coolant composition, glycol concentration, operating temperature, sealing materials, and long-term operating conditions before evaluating the compatibility of metallic wetted parts and elastomers. For water/glycol CDU loops, FRD can evaluate and configure materials and seals based on specific media and operating environments.

Differential pressure enables the control system to detect flow resistance variations across filters, heat exchangers, and fluid circuits, serving as a vital input for pump speed regulation and hydraulic balancing. Modern CDU testing also evaluates whether equipment can maintain target differential pressures or target flow rates across various operating states, rather than merely monitoring single-point static pressures.

It is recommended to provide at least the coolant medium and concentration, pressure or differential pressure range, media temperature, available installation space, process connection, output/communication protocol, and estimated annual volume. If the project involves specific requirements for sealing integrity, helium mass spectrometer leak testing, or custom envelope dimensions, these should be confirmed early during the prototyping phase. FRD's CDU collaboration workflow begins with piping structure and fluid verification, followed by structural adaptation, seal/thermal cycle validation, and volume delivery.
