Every 1 Bar in pressure drop equates to 7%increase in energy consumption. Consider a75kW compressor that uses 80kW consistentlyover 8,000 hours, with electricity cost of 25cents per kilowatt hour. 1 Bar pressure drop =$11,200 per year
AIR COMPRESSOR LIFE CYCLE COSTSEnergy
The yearly electrical cost of operatinga 75kW compressor that uses 80kWconsistently over 8,000 hours, withelectricity cost of 25 cents per kilowatthour is $160,000!

VARIABLE SPEED DRIVE
VARIABLE SPEED DRIVETraditional Compressors Generate Losses
VARIABLE SPEED DRIVE
Compressor Speed regulates to keep up with Demand– Eliminates Blow Off and Unloaded Losses
Keeping up with demand
VARIABLE SPEED DRIVE
Average saving 35% of energy– 35% x $160,000 = $56,000
Must Check!– Turn Down Ratio at least 80%– Oil Separator does not blow off– Hi Torque Motor– VSD Motor Bearings– Integrated Design– Adjustable Pressure
Traditional VSD
VARIABLE SPEED DRIVE
Average saving 50% of energy– 50% x $160,000 = $80,000
Same Benefits as traditional VSD except:– Uses highly efficient Oil Cooled Permanent
Magnet Motor, IP66– Optimised element Design– Direct Drive– Optimised Inlet valve– Smaller Cooling Fan– Smaller footprint– Lower noise levels
Next Generation VSD
ONSITE NITROGEN GENERATION
ON SITE NITROGEN GENERATION
Benefits of onsite generation– Cost– Self Reliance– Occupational Health and Safety– Continuous Supply
