Course Summary

Compressed air systems hold the key to greater productivity, efficiency and profitability in your facility. You just have to understand where to look and what to do. There is an increasing awareness that the systems approach to design and operation of industrial compressed air systems improves performance and productivity. A properly designed and functioning compressed air system reduces energy consumption and cost.

To optimise overall compressed air system efficiency, it is necessary to evaluate the whole system. Attempting to address individual parts of the system such as compressor control without evaluating issues of air storage, distribution and point of use can lead to incomplete analysis.Poor definition of system issues often results in treatment of symptoms. Failure to deal with the root cause of performance issues inevitably leaves the overall system with poor and inefficient operation.


Course Objective

In this workshop, you will learn the essentials of the systems approach, including compressed air system design from compressor to end use, piping and fittings, materials, codes and standards.

Learn how to optimize the system for performance, to create and maintain balance between system supply and end user demand. And learn to eliminate waste lost due to leakage and inappropriate use of compressed air. You will also gain an understanding of the maintenance issues that apply; the cost of air leakage, the methods of detecting and correcting system faults to ensure smooth operation.

Target Audience

Industrial compressed air system stakeholders who design, operate, and maintain the system will learn to improve reliability while reducing energy consumption and cost.

Production personnel and mechanics responsible for manufacturing processes and equipment powered with pneumatic energy will learn to solve problems that can interrupt production, reduce productivity, and affect product quality.

Energy engineers, managers, and program leaders will gain knowledge of the significant energy savings with optimized Compressed Air System Management and application of the Systems Approach.

Energy auditors and energy services leaders will learn the essential elements of a compressed air system assessment. Learn relevant variables in compressed air system performance that must be documented during an energy system assessment. These data are essential to successful correlation of post implementation measurement and verification of energy savings.
