Low suction and head pressure in a Liebert Mini-Mate2 MMD24E with a glycol system and free cooling could be caused by:
1. Low Glycol Solution Level – Insufficient glycol in the system can reduce heat transfer efficiency. 2. Improper Glycol Concentration – Incorrect glycol mixture can affect system performance. 3. Low Water/Glycol Temperature – If the temperature is too low, the free-cooling coil may take over, reducing suction and head pressure. 4. Restricted Flow in the System – Blockages or closed valves in the glycol piping can limit circulation. 5. Malfunctioning Three-Way Valve – If the free-cooling valve does not function correctly, it may divert flow improperly. 6. Dirty or Clogged Coil – A buildup of debris on the free-cooling coil can restrict heat exchange. 7. Air in the System – Entrapped air can reduce efficiency and cause pressure issues. 8. Pump Issues – A faulty or improperly sized pump may not circulate glycol effectively.
Checking glycol levels, valve operation, and system cleanliness can help diagnose the issue.
