ELGi Equipments, one of the world’s leading air compressor manufacturers, has witnessed wide adoption of the ELGi Heat Recovery System (HRS), a solution for utilising waste heat energy from an air compressor. Approximately 96 percent of the heat generated during the compression process, normally dispelled into the atmosphere, can now be recovered through the heat recovery system and then utilised to heat air (space) and water. This eliminates the need for additional equipment to heat air or water, thereby reducing CO2 emissions and energy consumption significantly.

The ELGi Heat Recovery System (HRS) is best suited for customers across process industries spanning paper, sugar, food and beverages, dairy, textiles etc, mainly companies who require compressed air and use hot water for their process requirements. The Heat Recovery System is a perfect solution for utilising waste heat energy from the compressor and finds applicability across companies committed to building energy efficiency in their compressed air system and paving the way for a clean environment.

One of its customers, a paper mill, experienced the benefits of the HRS system within the first few hours of installation, by way of continuous warm water availability with no external heating. With the implementation of HR 110, the customer was able to recover a heat load of ~89.14 kWh/0.077 MKcal through the continuous water supply of ~2,000 lit/hr at a temperature of ~70°C throughout the year. This resulted in an annual energy savings of 800-900 tonnes of LP steam and a carbon emission reduction of ~170-190 tonnes of Co2 /yr. With ELGi’s energy-efficient compressor and heat recovery system, the client was able to achieve significant energy savings resulting in accomplishing the target stipulated by PAT Scheme I and winning the prestigious GREENCO award.
