To remove air from a closed loop system, you need to "burp" the system. This process involves specifically targeting areas where air tends to accumulate.
Understanding Air Buildup in Closed Loop Systems
Air can get trapped in a closed loop system for a variety of reasons, and it's essential to remove it because it can reduce the efficiency of the system. When air accumulates, it can cause problems such as:
- Reduced heat transfer
- Increased corrosion
- System noise
The “Burping” Method
The primary method for removing air involves what's known as “burping” the system. Here's a step-by-step guide on how to perform this process:
-
Locate the Air Collection Points:
- Typically, air will collect in the system's highest points. This often means looking at components like:
- Side stream filters
- Pot feeders
- Typically, air will collect in the system's highest points. This often means looking at components like:
-
Open the Release Point:
- Once you have identified the location where air has accumulated, carefully open the valve or release point.
-
Fill Until Overflow:
- Slowly fill the location with system fluid until it starts to overflow. This forces trapped air out of the system.
-
Repeat If Necessary:
- If after the first attempt air is still trapped repeat the procedure until all the air has been removed.
Practical Tips
- Safety First: Always follow the manufacturer’s guidelines for your specific system.
- Regular Maintenance: Burping may need to be performed regularly, depending on how frequently the system is used or when new fluid is introduced into the loop.
- System Inspection: Regularly check for leaks or other issues that could be causing excessive air introduction into the system.
By following this method, you can effectively remove air from a closed-loop system and help it run more efficiently.
