Do evacuated tube systems require different maintenance in summer vs winter?

April 5, 2026

Quick Answer

Evacuated tube systems require more frequent cleaning in summer to maintain optimal performance, while in winter, they require more attention to ensure there is sufficient air pressure inside the tubes.

Summer Maintenance

In summer, the increased sun radiation and high temperatures cause the tubes to expand and contract more frequently, leading to the accumulation of debris and dust inside the tubes. Regular cleaning is essential to prevent these particles from affecting the system’s efficiency and performance. We recommend cleaning the tubes every 2-3 months, or as needed, using a soft brush and water to remove any debris.

Winter Maintenance

In contrast, winter brings colder temperatures, which can cause the air inside the evacuated tubes to contract and potentially create a vacuum. To mitigate this issue, ensure that the system’s inlet valves are open to allow air to enter the tubes and maintain the required pressure. We recommend checking the system’s pressure gauge monthly to ensure the air pressure inside the tubes is within the recommended range (0.05-0.1 bar). If the pressure is too low, consult the manufacturer’s instructions for guidance on how to re-pressurize the system.

Additional Tips

When performing maintenance on evacuated tube systems, it’s essential to follow the manufacturer’s guidelines and recommendations for specific maintenance procedures. Additionally, consider using a pressure gauge with a built-in thermometer to monitor the system’s pressure and temperature in real-time. By following these tips and performing regular maintenance, you can ensure your evacuated tube system operates efficiently and effectively throughout the year.
