The heat recovery system enables recycling of up to 96% wasted energy, leading to energy savings and reduced carbon emissions
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% 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 system is best suited for customers across process industries spanning paper, sugar, food and beverages, dairy, textiles, etc. These comprise companies that 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 our customers, a paper mill, experienced the benefits of the HRS 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 approximately 89.14 kWh or 0.077 MKcal through the continuous water supply of about 2,000 litres per hour at a temperature of around 70° Celsius throughout the year,” a press release stated.
“This resulted in an annual energy savings of 800~900 tons of LP steam and a carbon emission reduction of about 170-190 tons of CO2 per year. With the ELGi’s energy-efficient compressor and heat recovery system, our client was able to achieve significant energy savings resulting in accomplishing the target stipulated by PAT Scheme I and winning the prestigious GREENCO Award,” it added.
ELGi Equipments is a pioneer in cutting-edge compressed air technology with a presence across 100+ countries, offering a complete range of compressed air solutions from oil-lubricated and oil-free rotary screw compressors, oil-lubricated and oil-free reciprocating compressors and centrifugal compressors to dryers, filters and downstream accessories.
