Energy savings using variable speed drive air compressor technology

When you could be saving a third off your power usage; every air compressor user should know about VSD (variable speed drive) air compressors and how they can bring down the cost of operating a compressed air system.

To understand the potential for a VSD air compressor we should look at the total cost of ownership model for a air compressor over a 10 year period:
15% of the cost is the initial investment in air compressors and compressed air equipment
10% will go on maintenance costs
75% of the total cost will be payed through the electricity bill
energy electricity costs vsd variable speed drive air comrpessor

So lets use this as a basis to look at a case study.

The customer is looking for a 500 c.f.m. silenced air compressor.
After discussing this further and suggesting improvements to the current pipework system a 100 HP compressor is recommended.

Option1 - Standard Rotary Screw Air Compressor - producing 490.8 c.f.m.
Cost - £14,821.80 approx.

Option2 - VSD drive Rotary Screw Air Compressor - producing max 490.8 c.f.m.
Cost - £22,260.00 approx.

Now lets look at the total cost of ownership for option1 over a ten year period:
Capital Investment - £14,821.80
Maintenance - £9,881.20
Electrical Costs - £74,109.00
Total Cost - £98,812.00

Compare this to option2 over the same period:
Capital Investment - £22,260.00
Maintenance - £9,881.20
Electrical Costs - £55,581.75
Total Cost - £87,722.95

Thats a total saving of £11,089.05 over a ten year period.

Who would benefit most from a VSD machine?

Customers who have variable demands of air will benefit the most.
Clients who have capital to invest who are keen to save money in the long term.

Note: The calculations above use a savings figure of 25% which is perfectly reasonable considering many manufacturers are claiming over 30%.
