Compressor Heat Recovery

Compressor Heat Recovery

Nearly all of the energy that is used to power an air compressor gets converted to heat, 94% of which is available for heat recovery. Recovering the wasted heat from your air compressor could save thousands of pounds every year.

Retro Fit Heat Exchangers

Heat exchangers, like the Boge Duotherm, are typically used with oil lubricated screw compressors. When the oil in the compressor is hot enough it will bypass to a cooling system which allows the oil to cool down before re-entering the machine. A heat exchanger taps into this system and uses the hot oil on bypass to warm up cold water. The free hot water generated can then be used as part of processes on site or to simply reduce heating costs by being plumbed into your heating system. 


By ducting the hot air generated by your air compressor you can use this to heat offices or workshops during the cold months and bypass the heat outside during the summer. Direct Air can provide a fully costed solution on how to harness the wasted heat generated by your compressor in the most effective way.
