Summer’s Here – Is Your Chiller Keeping Up?

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.
