air audits for greensboro, raleigh, charlotte, and lynchburg areas, improve your energy efficiency

Discuss with Lewis Systems Audit Professionals the potential benefits of a compressed air audit.

We measure flow (scfm), power (kW), and pressure (psi). This information will present an accurate profile which allows us to determine Dynamic Efficiency. Obtaining this data enables us to offer cost saving options. Options that will improve your energy efficiency and save thousands of dollars in operating cost.

In the fall of 2008, Lewis Systems & Service was contracted by Graham-White to perform a supply side compressed air audit at our main manufacturing facility in Salem, VA.

During the week-long audit Lewis Systems recorded flow, pressure and amps for each compressor at 12 second intervals. After the audit was complete, Graham-White was provided with a complete study showing all of the captured data along with recommendations for improvements.

The recommendation with the greatest money saving potential was to purchase and install a Gardner-Denver model VS80 variable speed rotary screw compressor. The variable speed machine adjusts its speed based on plant air demand. The projected energy savings was around $17k per year. After the machine was purchased and installed a justification audit was performed, the actual savings was over $21k.

Manages up to 10 compressors
Efficiently adds and deletes compressors
Controls each compressor in the load/no load mode
Will rotate like size compressors to equalize wear

Our master controller is adaptable with any make and model air compressor. We can control Reciprocating, Rotary Screw and Centrifugal compressors.

A flow control device providing precise flow while maintaining pressure within ONE PSIG. Can be used as a stand alone device or in conjunction with an ESP 20/20 Master Controller.

Separation of supply from demand
Provides exact demand flow while maintaining pressure +/- 1 psi
Reduces system demand as a result of reduced system pressure

Plant can operate at a pressure never thought achievable.

I want to take this opportunity to thank Lewis Systems & Service for assisting me in a successful Six Sigma Green Belt 2009 project. Special thanks for the knowledge and expertise shared with the Facility Maintenance Team at Hollister Incorporated.

My project consisted of reducing the utility cost by 3% overall and with the assistance of Lewis Systems, we were able to surpass this goal and reduced the utility cost by 4.81%. Establishing a base/trim configuration on the air compressor system allowed us to reduce the number of compressors needed to meet production demands without compromising capacity.

I look forward to many more years of successful collaboration with Lewis Systems & Service and again thank you.
