Why is the rack temperature too high in my Vertiv Water System?
- R
  Ryan MoralesAug 15, 2025
  High rack temperatures in your Vertiv Water System can stem from several causes. Check for dirty filters and replace them if necessary. Ensure that remote temperature sensors are correctly positioned. Verify the cooling water temperature, as an inlet water temperature that is too high can also cause this issue. Additionally, cold air short-cycling or insufficient room cooling capacity can contribute to the problem, so verify unit positioning/room configuration and consider reducing the rack heat load or adding cooling units.
