Elgi Equipments Unveils Game-Changing Innovation in Compressor Technology | Demand=Match System

Chennai, India – 19 September 2025 – Elgi Equipments Limited, a global leader in air compressor manufacturing, today announced the launch of its latest innovation — the Demand=Match system. This intelligent system brings dynamic adaptability to fixed-speed compressors by smartly recirculating airflow to match real-time plant demand, delivering VFD-like energy savings without compromising the simplicity and reliability of fixed-speed machines.

“Compressed air is the fourth utility in every factory, but demand rarely stays constant,” said Dr. Jairam Varadaraj, Managing Director, Elgi Equipments. “Most fixed-speed compressors continue running at full output regardless of plant needs. Demand=Match brings intelligence to these machines, enabling them to adapt automatically — saving energy, reducing wear, and enhancing uptime, all without major capital investment.”

The Problem: Constant Output vs Fluctuating Demand: 

In typical manufacturing environments, air demand varies significantly throughout the day. Fixed-speed compressors manage this by cycling between pressure bands, which leads to:Energy waste, Pressure instability, Increased wear from frequent cycling 

The Solution: ELGi Demand=Match

Demand=Match technology resolves these issues by: Monitoring system pressure in real time, Modulating airflow via internal recirculation, Delivering exactly the required output — no more, no less

This approach ensures stable pressure, minimized cycling, and optimized energy usage.

Key Benefits:

• Up to 17% energy savings in real-world applications
• Improved equipment life through reduced mechanical stress
• Lower total cost of ownership with a capital-light implementation
• Reduced carbon footprint due to lower power consumption
• Extended warranties: Up to 10 years on EG series, 5 years on EQ series

“This system represents a major leap forward in compressor performance,” said Dr. K. Venu Madhav, Executive President – Product Excellence & Innovation. “It ensures the plant gets exactly what it needs — efficiently and reliably.”

Available immediately as a factory-fit option on ELGi’s EG and EQ series in India, the Demand=Match system supports ELGi’s mission to offer value-driven, energy-efficient solutions across key industries like textiles, automotive, pharmaceuticals, F&B, electronics, and general engineering.
