Almost three quarters of the lifetime costs of a compressor are attributed to energy. Take the example of a 250 kW compressor, running 3 shifts, 7 days a week, with electricity costs at $0.10/kWh. Over an average 10 year lifecycle that will cost $2.19 million to run in electricity costs alone!
You may be surprised to discover that with most compressed air systems only around 50% of the compressed air produced is actually production demand. With the example above, that means that over $1 million is being potentially wasted through; compressed air leaks (est. 25-30%), artificial demand (est. 10-15%) and inappropriate uses (5-10%).
However, here’s the good news. Many existing compressed air systems hide an energy savings potential of 30%
The first step in discovering the energy savings potential of a compressed air system would be to undergo a comprehensive compressed air audit. Big savings can be uncovered! As an example, the Air Demand Analysis (ADA) audit service from Kaeser Compressors was able to identify over 10,624,520.00 kWh of savings potential with some of its customers in 2016 in Australia and New Zealand alone. That’s $1,062,452.00 in possible savings (based on $0.10/kWh).
Based on the 2014 estimate that the average household’s electricity usage in New Zealand is 7,341 kWh per year, that’s the equivalent of taking 1,447 homes off the grid for one year!!
Is it time to realise your energy savings potential? If you only keep one New Year’s resolutions this year make it this one - to trim your compressed air “waste” line.
