Why Scheduled Maintenance Matters
An air-cooled modular chiller is built from precision parts, and a single failure can be costly. A routine inspection plan prevents expensive breakdowns and extends equipment life.
The Nine Areas to Check
- Compressor: The screw is a precision element that defines performance. Have a certified engineer inspect it every two years.
- Safety valve: Mounted on the condenser, it relieves excess pressure automatically. Check for aging and replace if defective.
- Scaling: Cooling towers, condensers, evaporators and pipes accumulate scale. Clean them roughly every six months.
- Lubricating oil: Quality degrades over time; change it at least once a year.
- Drier filter: Removes moisture from refrigerant; inspect yearly, or every six months in harsh conditions.
- Refrigerant charge: Top up promptly if low to protect the compressor.
- Electrical insulation: Verify main wiring, especially in damp environments, to avoid leaks.
- Hi/Lo pressure switches: These guard the compressor; abnormal readings disrupt operation.
- Thermostat: Confirm it displays correctly so operators can control temperature.
Takeaway
Treating these nine points as a standing checklist keeps the chiller efficient and reliable.
