Our Suggestion On Common Maintenance Issues
Issue 1: Leaking from compressor oil heat recovery unit
This issue may occur if the unit is running for a long period of time which exceed the operating temperature. The gasket became harden and thinner that caused leakage to occur.
HISAKA suggestions:
- Maintain operating temperature within design specification.
- Select a higher grade of gasket material.
- Plan proper preventive maintenance.
Issue 2: Waste water mud
This issue happens because of liquid flow is too dirty and contains a lot of waste. Not suitable plate gap will cause this fouling to happen very quickly which end up decrease the heat transfer efficiency of the heat exchanger.
HISAKA suggestions:
- Change to multi-gap plate pattern.
- Change to fully welded or spiral type heat exchanger.
- Add a number of plates or stand-by units.
