Study Notes
pH Tests in Closed Loop Systems
- pH tests are crucial to detect acidity in systems, especially when glycols are used.
- A falling pH level indicates that the inhibitor is being consumed and needs to be replenished.
- pH tests should be performed monthly for all systems.
Oxygen Scavenging in Heating and Cooling Systems
- Sodium sulfite is recommended to scavenge oxygen in heating and cooling systems.
- Systems treated with sulfite should have residual levels checked monthly.
- If a major leak occurs, sulfite levels should be checked immediately, and additional chemical should be fed to restore the proper concentration.
Testing for Glycol Systems
- Systems containing glycol should be tested annually for freeze point and inhibitor.
Corrosion Monitoring
- Corrosion coupons should be removed and tested every one to three months.
Conductivity Measurements
- Conductivity tests track dissolved solids resulting from corrosion or excessive make-up.
- Conductivity tests can be performed monthly.
Make-up Water Monitoring
- Make-up water usage should be monitored to detect leaks and optimize water treatment chemicals.
- Meters should be installed on the make-up water line to track usage.
- High make-up indicates leaks that require repair and a need for additional water treatment chemicals.
- Make-up water usage should be checked at least monthly.
Operator's Role in Closed System Monitoring
- Operators play a crucial role in monitoring closed systems.
- Frequent visual inspections for signs of leakage or corrosion are essential.
- Any leaks, loose insulation, or visible corrosion by-products should be addressed immediately.
