Reference Pigeon Carrières

PROJECT/REQUIREMENTS

• The quarry operates crushing, screening and conveyor systems with high energy and compressed air requirements. The previous system consisted of a 45 kW compressor (Compair L50) and an adsorption dryer.

  The aim of the project was to reduce energy consumption and ensure complete redundancy of the compressed air supply. An analysis revealed an idle rate of 63% and annual idle costs of around £8,500.

SOLUTION

• With the support of AIR ENERGIE, a RENNER RSF-PRO 2-37,0 D compressor with variable speed control was installed.

  This solution allows flexible adaptation to actual demand while ensuring the necessary redundancy.

   

IMPROVEMENT

• The new configuration provides:

• Idling completely eliminated
• Energy consumption significantly reduced (from 231 Wh/m³ to approx. 103–105 Wh/m³)
• High operational reliability thanks to 100% redundancy
• Significant cost savings and more sustainable operation
