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
