Elgi Equipments Limited (BSE: 522074 | NSE: ELGIEQUIP), one of the world’s leading air compressor manufacturers, yesterday showcased its Demand=Match System, an innovation that improves the way fixed-speed compressors perform under fluctuating air demand. Integrated with the ELGi EG and EQ Series air compressors, the system dynamically aligns compressor delivery to real-time plant requirements through intelligent internal airflow recirculation, delivering VFD-like energy savings with the simplicity and robustness of fixed-speed machines.
“Most factories rely on fixed-speed compressors that continue delivering constant output even when demand drops. ELGi’s Demand=Match System brings dynamic intelligence to these machines—automatically adjusting delivery to real-time demand, helping customers save energy, reduce wear, and improve uptime without heavy capital investment,” said Kasi PL, Head – Channel Sales, Elgi Equipments Limited, India.
The challenge: Constant output vs. variable demand
In most plants, compressed air demand varies minute-by-minute and shift-by-shift based on usage at the point of application. Fixed-speed compressors typically respond by cycling between cut-in and cut-out pressure bands, leading to:
Energy losses
Pressure overshoots
Frequent cycling that stresses critical components
These inefficiencies can increase operating costs and shorten equipment life.
The solution: ELGi Demand=Match System
ELGi’s Demand=Match is designed to automatically adjust compressor delivery to match plant demand. By intelligently recirculating airflow within the compressor, it maintains stable pressure and eliminates unnecessary cycling—even under fluctuating operating conditions.
Key customer benefits
Energy savings: Up to 17% energy reduction
Improved reliability: Reduced cut-in/cut-out cycling lowers mechanical stress and wear
Cost efficiency: A capital-light approach that enhances efficiency and keeps equipment “lifetime young”
Sustainability: Lower energy consumption directly reduces CO₂ emissions
Extended warranty: Available on EG and EQ series—up to 10-year airend warranty on EG and 5-year on EQ
The Demand=Match System supports ELGi’s strategy of delivering differentiated, value-driven solutions that help customers lower total cost of ownership. By making energy efficiency easier and more affordable to adopt, ELGi aims to accelerate uptake across industries including general engineering, food processing, rice & dal sorting, textiles, automotive, and electronics.
Availability: The ELGi Demand=Match System is available now as a factory-fit option on EG and EQ series compressors. For more information, please contact your local ELGi representative.
