Case study

Guardian Reliability Services recently conducted audits on three mills for a customer in Washington. During these audits, we identified multiple sources of oil leaks ranging from minor one-drop-per-second leaks to significant streaming leaks. Although such leaks might appear inconsequential at first glance, our analysis revealed the significant impact they have on operational costs.​

Using our Oil Loss Impact Chart, we illustrated the following:​

  • One drop per 10 seconds leads to a loss of 40 gallons per year.​
  • One drop per second escalates to 405 gallons lost per year.​
  • A streaming leak results in 8,640 gallons lost per year.​
  • Given the cost of industrial oil at approximately $10 per gallon, the financial impact of these leaks is substantial. For example, a single streaming leak could result in a loss of over $86,000 annually.​

By identifying and addressing hose and seal leaks in these mills, Guardian Reliability Services saved this customer almost $300,000 per year in oil costs alone. The return on investment for leak repairs was immediate, proving the value of a comprehensive audit.​

Our audits provide actionable solutions that enhance reliability, reduce waste, and drive significant cost savings for our clients.​​
