Cirebon Power: annual AQMS maintenance

1) Monthly preventive maintenance (12 visits)

Every month, a routine visit covers all AQMS devices:

• Thermo Scientific 42i (NO/NO₂/NOx Analyzer)

• Thermo Scientific 43i (SO₂ Analyzer)

• Thermo Scientific 49i (O₃ Analyzer)

• FH62C14 (PM10 Monitor)

• Environics 6100 (Multi-Gas Calibrator)

• Zero Air Generator

PM activities include:

• Cleaning the outer casing

• Visual inspection & internal cleaning

• Capillary inspection

• Fan filter cleaning

• Sample particulate filter inspection

• Lamp voltage check

• Leak test

• Pump check

2) Computer system & network checks

These include:

• Workstation

• Monitor & keyboard

• Printer

• UPS

• Communication switch

• Checks of the power supply, electrical disturbance, and data communication

3) Spare parts management

The document also lists the existing spare parts for each analyzer, including:

• O-ring

• Pump repair kit

• UV lamp

• Flow transducer

• Pressure transducer

• Filter element

This helps ensure critical components are available, which shortens MTTR (Mean Time to Repair).

4) Proposed implementation

The document sets out a monthly PM schedule (Month 1-12) with a detailed checklist for each instrument.
The aim is to keep all devices in optimal condition throughout the year.
