ELGi makes a breakthrough in fixed-speed compressor performance with patented ELGi Demand=Match System™

Delivering up to 17% energy savings, longer equipment life, and lower operating costs through intelligent demand-responsive air compression

Developed to address one of the most persistent inefficiencies in compressed air systems, the ELGi Demand=Match System enables fixed-speed compressors to operate more intelligently under fluctuating demand conditions. The technology delivers up to 17% energy savings, extends equipment life, and lowers operating costs while maintaining the simplicity, robustness, and reliability that customers expect from fixed-speed compressor technology.

Compressed air demand is rarely constant. Across industries such as automotive, packaging, ceramics, cement, food processing, metalworking, laser cutting, vehicle service stations, and general manufacturing, air demand fluctuates throughout the day as operating conditions in production lines change.

Traditional fixed-speed compressors, however, continue producing compressed air at a constant rate. This mismatch between supply and demand often creates pressure spikes within the system, leading to unnecessary energy consumption, increased air leakage, excessive compressor cycling, and accelerated wear on critical components. Over time, these effects can increase maintenance requirements, reduce equipment life, and raise the total cost of ownership.

Recognising this challenge, ELGi engineers set out to develop a solution that would allow fixed-speed compressors to become flexible when demand changes and reliable for life.

Introducing the ELGi Demand=Match Technology

Utilising ELGi’s proprietary patented innovations, the Demand=Match System intelligently regulates the compressed air flow and helps eliminate waste while maintaining stable system performance.

In simple terms, customers only pay for the compressed air they actually use.

Key Customer Benefits

Up to 17% Energy Savings

Field test results demonstrate energy savings of up to 17% under typical operating conditions by reducing the production of excess compressed air.

Longer Equipment Life

Reduced pressure fluctuations and fewer cut-in/cut-out cycles minimise mechanical stress on critical components, helping extend compressor and system life.

Lower Operating Costs

Lower energy consumption, reduced maintenance requirements, and improved equipment longevity contribute to a lower total cost of ownership throughout the compressor lifecycle.

Stable and Reliable Operation

By continuously matching output to demand, the ELGi Demand=Match delivers consistent pressure and dependable performance even in applications where air consumption changes frequently.

Flexible When Demand Changes. Reliable For Life.

“Manufacturers today operate in environments where compressed air demand is constantly changing, yet most fixed-speed compressors continue to produce air at a fixed output regardless of actual requirements,” said Nils Blanchard, Vice President, ELGi Europe. “With our patented ELGi Demand=Match System™ technology, we have fundamentally changed that equation. By ensuring the compressor produces only the air that is required, customers can reduce energy consumption, lower operating costs, and extend equipment life without sacrificing reliability. Demand=Match delivers exactly what modern manufacturers need: flexible when demand changes and reliable for life.”

The benefits of the ELGi Demand=Match are already being demonstrated in real-world operating environments where fluctuating compressed air demand is a daily reality.

At Esencia y Sabor de la Dehesa Extremeña, a leading Spanish food producer, the technology delivered measurable efficiency gains while maintaining operational stability.

“With ELGi’s Demand=Match System, we have experienced stable pressure and up to 10% lower energy use,” said Cristian Escobar, Maintenance Technician at Esencia y Sabor de la Dehesa Extremeña.

Similar results were achieved at Valla Homes, where the technology helped improve both efficiency and production performance.

“ELGi’s Demand=Match System delivered energy savings of up to 16%, while helping improve productivity and quality,” said Lee, Engineering Technician, Valla Homes.

These customer experiences demonstrate how the ELGi Demand=Match adapts to fluctuating air demand, helping manufacturers reduce energy consumption, lower operating costs, and extend equipment longevity while maintaining reliable compressed-air delivery.
