Why do we need two loops for liquid cooling?

• For high quality facility water which is not available in most Data Centers - a secondary loop is required between the cold plates and the Chiller, also known as TCS (technology Cooling system) and FWS (Facility Water system). This helps achieves the highest quality of water while keeping WUE low. Most systems have 20%-35% Water glycol mix
• Precision control of the coolant
• The CDU can control the pressure, flow and temperature. To help manage the AI workloads which can go from 4MW to 130MW in milliseconds
