A Coolant Distribution Unit (CDU) is a purpose-built system that enables liquid cooling for servers without exposing delicate IT hardware to potentially corrosive or impure facility water systems (FWS). It acts as a thermal and hydraulic interface between the facility cooling system and the technology cooling system (TCS) used to directly cool IT equipment such as cold plates, rear door heat exchangers, or direct-to-chip cooling systems[

Modern data centres demand more than just cooling—they require precision. With rising thermal loads in high-density server racks, traditional hydronic systems often fall short in delivering consistent, reliable performance. That’s where automatic balancing becomes a critical factor—especially in CRAC (Computer Room Air Conditioning) and CRAH (Computer Room Air Handling) loops.

As data demands rise, so does the thermal load in server environments. In today’s digital infrastructure, high-density server racks are becoming the norm—housing more power-hungry equipment in tighter spaces. Without a proper rack cooling strategy, the result is increased risk of hot spots, higher energy costs, and compromised performance.
