It is a surprising fact that 100% of the electrical power (energy) is converted to heat energy during the Compression process in an Air compressor & all the heat energy goes as a waste if not used judicially. Keeping in mind the effects of Global warming in the present environment. ELGi has come up with a system where 78% of the waste heat generated by the compressor can be utilised for heating water. This in turn eliminates the necessity to go for additional equipment to heat water, thereby reducing the CO2 emission to a large extent.
