ENERGY SAVINGS AVAILABLE VIA PRESSURE REDUCTION

Energy Savings = 8% kW rating x pressure reduction x operating hours

EXAMPLE 1:

Reducing the system pressure on a 100 Kw air compressor from 8 bar to 7 bar operating for 8000 hours per year

Energy Savings = 0.08 x 110 KW x 1 Bar x 8000 = 70,400 kWh per year $7,040 (@ $0.1/kWh)

*Reducing compressed air supply pressure by 50 kPa = 4% reduction in power usage
