Summer’s Here – Is Your Chiller Keeping Up?

June 23, 2025

With temps soaring, your glycol chiller is under more pressure than ever. Higher ambient conditions push your system to its limits—so if you haven’t already done a seasonal check-up, now’s the time.

To help you stay cool and avoid mid-season breakdowns, we’ve put together a Glycol Chiller Summer Maintenance Checklist. Whether you’re running a brewery, winery, or production facility, this list can help keep your operation smooth and stress-free.

✅ Summer Maintenance Checklist

  • Clean condenser coils
    Dust and debris choke airflow and reduce heat transfer. Clean coils = better efficiency and cooler temps.
  • Check glycol levels & concentration
    Ensure your fluid is within the recommended ratio (typically 35-40% for propylene glycol) and topped off.
  • Inspect for leaks
    Look for signs of leaks around fittings and pumps. Even small drops can lead to major problems.
  • Verify temperature setpoints
    Double-check that your control settings match your current production load—no overcooling, no overheating.
  • Log compressor pressures & fluid temps
    Monitor key data to catch any developing issues before they turn into costly service calls.
  • Confirm fan and pump operation
    Make sure fans and circulation pumps are running at optimal speed and not drawing excess amperage.

🧊 Hot Weather Tips

  • Keep airflow unobstructed
    Maintain proper clearance around air-cooled condensers. No storage near intake or exhaust areas.
  • Inspect insulation
    UV and weather exposure can degrade glycol lines—damaged insulation means heat gain and energy loss.
