Energy audit of compressed air system: J.M. Huber and Forchem Oy
09 Декември 2013

Summary: J.M. Huber and Forchem Oy carried out energy analyses for their compressed air systems. An annual electricity saving potential of 640 MWh was found. That is approximately 30% of total electricity consumption in companies’ compressed air systems. (Main content in Finnish)


  • J.M. Huber started to observe electricity consumption of compressed air system in weekly team-meetings already before the energy audit. They halved the consumption from the point they started this action and energy audit gave certainty that compressed air system work efficiently. (Most of the energy efficiency actions from the audit were already known because of systematic daily observing of consumption.)
  • Compressed air system consumes approximately 5% of total electricity consumption of Forchem´s processes. Forchem did an audit and it is possible to reduce one third of the electricity consumption of compressed air system by measures from audit.
