A prospect informed about a possible massive cost of compressed air leaks responded:
“What leaks? I do not hear hissing noise from compressed air leaks on the floor.”
Plant manufactures gravel. Production noise is deafening. To hear compressed air leak would be a disaster, not only for energy bill, but likely for the whole production process.
If leaks are not managed regularly, aka found and fixed, a typical energy waste on leaks alone is 30%.
Here is how to calculate what it means for the hydro bill:
Cost of leaks = Compressor rated capacity *0.75* Annual hours of operation * Average compressor load * Level of leaks * Cost of kWh
It is not rocket science, it’s common sense and good maintenance.
