Key components of an air audit
- Data collection: Monitoring energy use, air flow, pressure levels at various points, and air quality (like dew point).
- Supply side analysis: Evaluating the efficiency of compressors, dryers, and storage tanks.
- Demand side analysis: Assessing how and where compressed air is used, including the distribution piping and end-use equipment.
- Leak detection: Using specialized equipment to find and prioritize air leaks, which are a major source of waste.
- System evaluation: Looking for problems like over-pressurization, poorly sized piping, and inefficient equipment or controls.
Benefits of an air audit
- Cost savings: By identifying and fixing leaks, improving efficiency, and optimizing equipment, audits can lead to significant energy and cost reductions.
- Increased efficiency and productivity: Optimizing system performance ensures air is available when and where it’s needed, reducing production downtime and improving efficiency.
- Problem identification: Audits uncover hidden problems that are not always obvious, such as the misuse of air or improperly sized components.
- Strategic planning: The data from an audit can help justify investments in new equipment and guide future system expansion plans.
- Environmental impact: Reducing energy consumption through system optimization also lowers the environmental impact.
