Two regulated-speed compressors from CompAir have helped Astrum, a steel components manufacturer, to cut its compressed air energy costs by more than a half and increase productivity at its foundry in County Durham.

Astrum was able to benefit from an interest-free loan from the Carbon Trust to fund the installation, thanks to the high energy efficiency of its new compressed air system.

Mike Hutchinson, Astrum operations director says: “One of our key areas of spend is our compressed air system, which is critical to the plant performance and fundamental to our processes for moving sand around the foundry and operating industrial equipment. We approached CompAir distributor, Air Energy Management to assess our air requirements.”

Air Energy Management developed a bespoke system to reduce the demand on compressed air and replaced old, large compressors with two more efficient, smaller CompAir compressors.

The CompAir L75 RS and L160 RS compressors both feature regulated-speed technology and are protected and monitored by a Delcos 3100 electronic control system.

The new system will reduce Astrum’s compressed air energy demand by 1,255,000kWh and save it over £80,000 per annum.
