As summer approaches, rising temperatures and increased humidity can put extra stress on your compressed air system. From compressors and dryers to other critical components, the warmer months can create challenges that impact performance, efficiency, and reliability. 

The good news is that a little preventative maintenance now can go a long way. Taking the time to inspect and service your system before the heat arrives can help reduce the risk of unexpected downtime, improve energy efficiency, and keep your operation running smoothly all season long. 

To help you prepare, we’ve outlined a few key areas to check before summer is in full swing. 

1. Clean and Inspect Heat Exchangers

Heat exchangers, including aftercoolers and oil coolers, play an important role in keeping your compressed air system cool and operating efficiently. As temperatures rise during the summer, these components work even harder to regulate temperatures and remove moisture from the air. 

Over time, dust and debris can build up on cooling surfaces, reducing airflow and efficiency. A quick inspection and cleaning before summer can help prevent overheating, improve performance, and keep your system running reliably when you need it most. 

 

2. Verify Condensate Drain Operation

Warmer temperatures and higher humidity levels generate more condensate throughout your compressed air system. If drains become clogged or fail to operate properly, moisture can accumulate in air lines and equipment, leading to corrosion, contamination, and reduced performance. Inspect all manual and automatic drains to ensure they are functioning correctly.  

3. Evaluate Air Dryer Performance

Air dryers are crucial during periods of high humidity, especially in the summer. Whether your system uses refrigerated dryers or desiccant dryers, ensuring proper operation before summer can help maintain clean, dry compressed air. 

For refrigerated dryers, inspect condenser coils, cooling fans, and airflow paths for signs of dirt or obstruction. For desiccant dryers, check pre-filters, drains, and filtration components to prevent moisture and oil contamination from reaching the desiccant bed. 

 

4. Service Oil/Water Separators

Oil/water separators provide an environmentally friendly way to manage moisture generated by compressed air systems. During periods of increased moisture production, these systems may experience higher demand. 

Inspect separator components and replace carbon bags and filters. Regular maintenance helps ensure reliable operation and proper condensate disposal throughout the summer season. 

 

5. Check Ventilation and Airflow

Compressor rooms can experience significant temperature increases during the summer.  Poor ventilation can cause equipment to operate at high temperatures, reducing efficiency, and increasing the risk of shutdowns. 

Inspect ventilation fans, louvers, and intake openings to ensure proper airflow. Keeping compressor rooms cool can improve equipment reliability and extend component life.

6. Inspect Filters and Perform a Leak Audit

Dust, pollen, and airborne debris are often more prevalent during the summer months. Inspect intake filters and replace them as needed to maintain proper airflow and compressor efficiency. 

Also, it’s important to conduct a system-wide leak audit. Even the smallest air leaks can increase operating costs and force compressors to work harder during periods of peak demand. Addressing leaks can improve system efficiency and reduce energy consumption. 

 

Stay Ahead of Summer Challenges 

Preventative maintenance can help you stay one step ahead. Don’t wait until a heat-related issue impacts production. Schedule your summer maintenance today and keep your compressed air system operating at peak performance all season long.
