Direct Conclusion
Fouling is a common cause, but it could also be due to vacuum system leaks, reduced ejector efficiency, or elevated cooling water temperature.
Judgment Criteria
- 01
Check the temperature difference between cooling water inlet and outlet against the condensing temperature. If the temperature difference decreases while water temperatures remain normal, scaling is likely.
- 02
Perform vacuum tightness test to rule out system leaks and issues with the extraction equipment.
