Problem

The compressed air system was over 25 years old, and very energy inefficient due to competing compressors. Energy prices increased from $0.069 to $0.139 kWh, driving the cost of compressed air electricity for the site from $350,000 to over $700,000 per annum.

Solution

Replace the existing seven compressors with:

  • 3 new Ingersoll-Rand 2 stage IRN 160 KCC compressors (two operating, one back-up)
  • 2 Hankison HPRP1750 refrigerated dryers with inbuilt filtration to improve air quality
  • All equipment was installed using 100mm Aluminium Transair piping
