Elgi launches IoT-Based Air Compressor Monitoring System

Coimbatore based air compressor manufacturer Elgi Equipments has launched Air~Alert, an IoT-based Air Compressor Monitoring System in the Indian market.

Air~Alert is a data transmission and analysis service that monitors critical parameters and sends out actionable insights and alerts to users.

“With these insights, customers can improve uptime and maximise efficiency with smart monitoring and data related to air compressor performance,” Elgi said in a press release.

The service also enables customers to act in time and avoid potential failures. Additionally, Air~Alert enables 24×7 remote monitoring of the air compressor

It delivers trend graphs and information about operating parameters, including discharge pressure, oil temperature, variable frequency drive (VFD) speed (where fitted), total running hours, trips, and alerts on a live online interface, accessible remotely from anywhere in the world.

Air~Alert also notifies customers and Elgi channel partners about scheduled maintenance and fault occurrences while predicting commonly occurring failures.

Monthly summary reports on overall health and operating parameters, including upcoming service requirements and preventative maintenance based on the data obtained, are sent to customers.

The operational and performance data from compressors are acquired by Air~Alert from the compressor controller, transmitted in an encrypted form, and sent to secure and dedicated Air~Alert cloud servers.

Smart algorithms then work on the data to enable intelligent prediction with actionable alerts, reports, and trends, which are returned securely to the operators as easy-to-read actionable dashboards.

Throughout the process, the data is structured and analysed to provide smart analysis that helps users to plan maintenance activities, enabling energy efficiency improvements with the compressor.

The Air~Alert failure prediction module also predicts if the compressor is likely to fail in future. At end of the process, data is translated into comprehensible alerts and reports that allow user to take timely action.

“With Elgi’s Air~Alert, users can track highly informative utilisation trends providing actionable intelligence and take corrective actions,” the company added.

These include operating pressure band optimisation based on the utilisation rate and also replacing an existing fixed speed unit with a variable speed VFD unit/ or adding a retrofit VFD

Actions also include providing an energy efficient, lower size compressor in case of very low utilisation rate and detecting leaks based on an unexpected change to a higher utilisation rate over time.
