Event Details

Date: 20 & 21 March 2023

Time: 9.30am - 5.30pm

Mode of delivery: Virtual Live Class via Zoom


In this workshop, you will learn the essentials of compressed air systems for improving their energy efficiency. It includes compressed air system design from compressor to end use, piping and fittings, materials, codes and standards, and waste heat recovery.


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