Energy & Maintenance Cost
Comparison
Electric vs. Diesel Driven
Compressor Solutions
Recently we
had the opportunity to take a detailed look the difference
in operating and maintenance costs associated with the
production of 6500 SCFM at 300PSIG of compressed air. Two
options were considered, the first using temporary electric
motor driven compression equipment and second diesel driven
compression equipment.
Summary: As outlined below,
electric motor drive compression solutions offer substantial
energy & maintenance savings when compared to the diesel
alternative. For this given requirement the savings were in
excess of $170,000 per month.
