Compressed air is your most expensive
utility
This is a fact that has been documented time
and time again. It takes 7 to 8 HP of electricity to produce
1 HP worth of air force. This high-energy cost quite often is
overlooked.
Evaluating Energy Costs
Depending on plant location and local power
costs, the annual cost of electrical power can be equal to,
or as much as twice the initial cost of the air compressor.
Over a ten-year operating period, a 100 HP compressed air system
that you bought for £20,000 will accumulate up to £250,000
in electrical power costs. Following a few simple steps can
significantly reduce energy costs by as much as 35%.
The graph below shows the relationship between compressor HP
and energy cost:
COMPRESSOR ANNUAL ENERGY COSTS
We consider ourselves experts in the field
of compressed air and energy efficiency and we are more than
willing to give advice on anything concerning this.
We can offer a site survey where we can ascertain the extent
of any energy wastage and prioritise the work required to maximise
energy savings.
A site survey could include all
or a selection of the following: -
Air Measurement:
an accurate account of your plant’s compressed air demand
over a 7-day cycle, identifying energy costs and where savings
can be made.
Air leak detection and control:
with leaks typically accounting for 20% of the system demand,
this is a critical efficiency procedure.
Air quality audit:
measures the quality of air against your specific needs at any
point in your system.
Maintenance Review:
assesses service programme effectiveness for equipment, including
compressors, filters, dryers and ancillaries.
Monitoring and control programme:
sets out recommendations for long term monitoring and control
to maintain optimum efficiency.
After completion of any or all of the above
you will receive a comprehensive report and a CD which includes
a PowerPoint presentation of the results.
