ELGi Compressors, a leading global manufacturer of compressed air systems, continues to innovate in air compressor technology with a focus on improving energy efficiency and reducing the environmental footprint of manufacturing operations. With a wide dealer network in Australia and an expansive product portfolio, ELGi aims to help customers achieve higher productivity while minimizing operational costs.
The company offers a comprehensive range of compressed air solutions, including oil-lubricated and oil-free rotary screw compressors, reciprocating compressors, dryers, filters, and downstream accessories. With over 400 products, ELGi serves a variety of industries worldwide, catering to the increasing demand for energy-efficient technologies as concerns over global warming intensify.
Focus on Energy Efficiency and Sustainability
ELGi has long been committed to improving its product efficiency, particularly in terms of specific power consumption. The company’s ongoing efforts have culminated in the development of its latest product innovations, including the air-cooled direct drive series featuring a Permanent Magnet Synchronous Motor (PMSM).
The new EG Series has been upgraded with the introduction of the EG PM (Permanent Magnet) oil-lubricated screw air compressors, available in power ranges from 11 kW to 45 kW. The EG PM models promise up to 15% improved efficiency and a 16% increase in Free Air Delivery (FAD), positioning the series as a leader in both performance and energy savings. These compressors are designed to deliver superior energy efficiency, offering long-term value across various load capacities.
Cutting-Edge Features for Maximized Performance
The EG PM Series incorporates a host of intelligent features designed to minimize energy consumption while reducing the overall environmental impact. Central to its high efficiency is the ultra-efficient IE5+ permanent magnet synchronous motor, which offers efficiency ratings between 96.5% and 97.6%—significantly higher than the industry standard. This motor, specifically designed for ELGi’s airends, maximizes energy efficiency while reducing the carbon footprint of operations.
The system’s direct coupling ensures that motor and airend speeds are optimized for synchronous operation, which is particularly effective in variable-speed applications. Additionally, the EG PM Series is equipped with an intelligent thermal valve system, which uses ambient temperature sensors to maintain the oil at an optimal operating temperature. This prevents overheating during colder months, further improving energy efficiency.
The Neuron 4 controller, an integral part of the EG PM Series, offers comprehensive control for superior compressor operation. Featuring a 7-inch touchscreen interface and advanced algorithms, the Neuron 4 controller optimizes energy use, enhances operational efficiency, and enables proactive maintenance through real-time data analytics.
PMSM Motor: A Technological Breakthrough
ELGi has also introduced its own robust, IP55-rated PMSM motor, which offers significant advantages over traditional induction motors. While induction motors typically fall within the IE4 efficiency range, ELGi’s PMSM motor delivers the lowest energy losses among all available motor technologies. The precise synchronous technology used in the PMSM motor enables efficient feedback and input processes, ensuring that the compressor operates at optimal efficiency even under varying load conditions.
Unlike most permanent magnet machines on the market, ELGi’s design allows for independent servicing of both the airend and motor, providing added flexibility and longevity for customers.
Advanced Thermal Management and IoT Integration
The EG PM Series also includes an intelligent thermal valve (ITV) system, which works in conjunction with the Neuron 4 controller to optimize the compressor’s thermal management. The ITV system reduces thermal stress on the oil by adjusting to changes in ambient and lube temperatures, helping maintain optimal oil temperatures and flow. This efficient thermal management reduces the load on the airend, leading to substantial energy savings.
Additionally, ELGi offers an optional Air Alert system, an IoT-enabled monitoring and alert system designed to track the performance and energy efficiency of the compressor in real-time. Compatible with ELGi’s full range of compressors, Air Alert enables 24/7 remote monitoring, allowing users to optimize compressor performance and prevent costly downtime.
A Commitment to Reliability and Longevity
For added peace of mind, the entire EG range, including the EG PM and SP series, comes with a robust warranty package. This includes a 10-year warranty on the airend, 5 years on key compressor components, and 3 years on the variable frequency drive (VFD).
ELGi’s commitment to innovation and sustainability is encapsulated in the company’s motto, ‘Always Better,’ which drives continuous improvements in its products. By maximizing efficiency, dependability, and reducing environmental impact, ELGi aims to lower the total lifecycle costs of its customers’ operations while contributing to a more sustainable future.
In an era where energy efficiency is paramount, ELGi Compressors continues to lead the way in providing advanced, eco-friendly solutions that help manufacturing companies reduce their carbon footprint while boosting productivity.
