As industries demand smarter, more energy efficient compressed air solutions, rotary screw air compressors remain the backbone of industrial compressed air systems. However, traditional fixed speed compressors often struggle to adapt to real time air demand fluctuations on the shop floor. ELGi Equipments Limited’s latest innovation, the Demand=Match System, addresses this very challenge, offering significant energy savings and enhanced operational performance for screw compressor installations. As an authorized ELGi channel partner (VEMC), we dive deep into why this technology matters and how it can benefit your business.
Understanding Screw Air Compressors & Their Importance
Before exploring Demand=Match, it is important to understand why screw air compressors are widely preferred:
- Continuous compressed air delivery: Unlike reciprocating compressors, rotary screw air compressors provide uninterrupted airflow ideal for industrial use.
- High energy efficiency and reliability: Screw compressors are designed for continuous operation with fewer mechanical stresses and low maintenance requirements.
- Low noise and vibration: They operate quietly compared to conventional compressors, creating safer and more comfortable working environments.
As demand for compressed air varies across production cycles, ensuring an efficient match between compressor delivery and actual plant demand becomes critical this is where ELGi’s Demand=Match technology transforms performance.
What is the ELGi Demand=Match System?
ELGi’s Demand=Match System is an intelligent airflow control solution that enhances fixed speed screw compressors by automatically adjusting air delivery to match real time demand on the plant floor.
Traditionally, fixed speed compressors operate at a constant output. However, in real industrial environments, air demand fluctuates minute by minute, leading to frequent cycling, energy waste, and inconsistent pressure. Demand=Match smartly recirculates airflow inside the compressor to ensure delivery always equals demand, eliminating inefficiencies.
Key Technical Benefits of Demand=Match
1. Significant Energy Savings
With Demand=Match, screw compressors can deliver up to 17% energy savings in typical operating scenarios where demand varies.
This is similar to the benefits seen with Variable Frequency Drives (VFDs), but delivered through intelligent airflow control without investing in expensive VFD systems.
2. Reduced Mechanical Wear & Better Reliability
Frequent start stop cycles and pressure spikes cause mechanical stress and premature component failure. The Demand=Match system reduces these cycles, resulting in:
- Lower bearing and air end stresses
- Longer service life
- Increased uptime
This improves overall reliability of your compressor system.
3. Stable System Pressure & Operational Consistency
Demand=Match continuously monitors system pressure and adjusts airflow dynamically, resulting in stable pressure delivery even under fluctuating load conditions.
4. Lower Total Cost of Ownership (TCO)
Demand=Match is a capital light upgrade that delivers performance close to VFD systems without the typical costs. It optimises energy use and reduces operating costs, positively impacting your bottom line.
5. Sustainability and Reduced Carbon Footprint
Energy savings directly translate to lower power consumption and reduced CO₂ emissions, a critical factor for industries pursuing sustainability and eco efficiency goals.
Where Demand=Match Makes a Difference
This innovation isn’t just theoretical; it has widespread applicability across industries where screw air compressors are critical to operations:
✔ Textiles, apparel and fabric production
✔ Automotive manufacturing and assembly lines
✔ Food & beverage processing
✔ Paper and pulp applications
✔ Small and large machining workshops
In every case, compressed air serves as key utility powering pneumatic tools, process controls, packaging lines, instrumentation, and more. Matching compressor output to demand improves efficiency and reduces operational variability.
