Based on the previous post, I looked at our compressed air systems which is set at 125 psig. I wanted to know what kind of opportunities that would exist for the system?
Compressed air is one of the most energy intensive utilities in industry, often accounting for 10 30% of a plant’s electricity use. Common savings opportunities include repairing leaks, lowering system pressure, using staged or variable-speed compressors, improving end-use practices, etc. For example, a leak due to a small orifice of size of 1/32 inches can cost about $230 each year.
Wow! Thank you for providing such great information. What are the methods to identify such opportunities and is there a some rule of thumb that exist? Can ITACs help with it? We are in Ohio.
Happy to help. Various leak test and other methods exists to identify such opportunities. We can help you connect with University of Dayton ITAC (University of Dayton) who serves Ohio. For rule of thumb you can refer to Cheat Sheet developed by DOE’s Better Plants program: https://betterbuildingssolutioncenter.energy.gov/sites/default/files/attachments/BP%20Compressed%20Air%20Cheat%20Sheet.pdf.
