Research and Development Facility

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 does this GA18VSDs compressor save so much energy and money?

Atlas Copco’s 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.
