ELGi introduces STABILISOR technology for air compressor efficiency

It sets new standards in compressed air reliability, energy costs, and variable flow; the STABILISOR system utilises the ‘Recirculate and Recover’ approach, optimising compressor capacity by adjusting to plant air demand through controlled recirculation and recovery methods.

Elgi Equipments has pioneered compressed air stabilization technology  It is designed to revolutionise the way compressors operate in plants with dynamic air demand. The STABILISOR system aims to address the challenges of unstable compressor performance, inefficiency, and excessive wear caused by frequent load/unload cycles.

In industrial settings, the gap between compressor capacity and plant air demand is inherently dynamic. This variability leads to frequent cut-in and cut-out operations, which destabilise the compressor and impair critical flow and kinematic components. Traditional solutions, such as increasing reservoir volume, altering cut-in/cut-out pressures, or adding variable frequency drives (VFDs), often fall short, introducing new inefficiencies or higher operational costs.

Dr Jairam Varadaraj, Managing Director, Elgi Equipments Ltd. said, “The STABILISOR system employs a first-of-its-kind “Recirculate and Recover” principle, seamlessly aligning compressor capacity with plant air demand through controlled recirculation and recovery techniques. By stabilising airflows within the system, the STABILISOR system minimises load/unload cycles, ensuring extended equipment lifespan, optimises energy use, achieving up to 15% energy savings in typical applications, while reducing system inefficiencies, maintaining superior performance across varying demand patterns. With its energy-efficient design and potential to reduce wear and tear, the STABILISOR aligns with global sustainability goals. Its implementation in industrial plants represents a shift towards greener, more cost-effective manufacturing processes.”

Dr Venu Madhav, Director of Technology at Elgi Equipments Ltd., said, “The STABILISOR system utilises precision-engineered progressive and on-off valves to recirculate excess capacity within the system. This system leverages stabilisation zones and low-pressure recovery techniques to balance airflow demands dynamically, minimise energy losses by targeting pressure points with minimal differences, and maximise overall system reliability.”

To meet diverse operational needs, the STABILISER system will be available in India and across the globe in 2025 in two versions:

• Light Version: Designed for field fitment, energy savings and enhanced reliability.
• Heavy Version: Factory-fitted for superior energy savings and comprehensive stability.

The STABILISOR’s innovative design and control methodology is patented worldwide, marking it as a pioneering advancement in compressed air technology.
