Changes to Air Compressor Save Energy and Dollars

0 Comments

As the bureau's Sustainbility Coordinator, I thought I should share this tidbit with you, written by PWB Engineer, Peter Nierengarten:

 

Changes to an air compressor at the bureau's Interstate Facility will save energy and dollars going forward.Recent operation changes for the air compressor at the Water Bureau's Interstate facility are saving money and lowering the bureau's carbon footprint.

Continuous operation of an existing 1950's era compressor consumed nearly 45,000 kilowatt hours per year and cost the bureau more than $4000 to operate. Recent changes to the 100 horsepower system included repairing two leaks, lowering the operating pressure, and changing from continuous to on-demand operation.

These changes significantly lower operation time and require only minimal staff time with no capital investments. Preliminary billing numbers indicate a 90% reduction in electricity use. The Water Bureau will save over $3000 per year!
