• Customer:  Research and Development Facility
• Reason for audit:  Our team reported the compressor as being old and oversized for the application.
• Current compressor:  Compair Cyclon 345 (45kW)
• Cost of electricity:  £0.30 /kWh (value supplied by customer)
• Results of Audit:  Confirmed to be oversized and inefficient.
• Measured potential savings:  91.7% = £12,537/year
• Simulated compressor:  Atlas Copco GA18VSDs (11kW) IE5
• ROI on equipment:  12 months

How did this GA18VSDs compressor save so much energy and money?

Atlas Copcos state-of-the-art element in a unique vertical configuration with an ultra-premium efficiency (IE5) ferrite assisted synchronous reluctance motor. This new motor technology equals IE5 efficiency without the need of rare earth materials, making it a completely sustainable solution.

Above is a energy (Amps) chart showing the compressor running condition, running on load, running unloaded (not pumping air), and stopped.

Green is loaded running efficient use of power.

Orange is unloaded running, not producing air wasted electricity.

The compressor was clearly oversized, stop-starting too regularly and running mostly off-loaded (orange) and inefficiently.
