16% energy drop
May 1st 2007 Henrob, a world leader in selfpierce
fastening technology, has
realised a 16% drop in energy
costs over a period of just three
months by installing a Boge SF
100-2 frequency controlled screw
compressor.
Henrob design and manufacture
joining solutions using its selfpierce
riveting (SPR) technology
which is used in many industry
sectors, such as the; construction,
heating & ventilation and
automotive industries.
As John Aldridge, the equipment
operations manager explains; "Like
many businesses we have noticed
a steep rise in our energy costs as
a result of increased electricity
prices over the past months. As
compressed air accounts for a high
proportion of our site energy costs
it became imperative for us to
review our compressed air system
to ensure we were operating as
efficiently as possible.
Derek Yates, managing director
of the local Boge distributor
Compressor Care (N.Wales)
suggested an energy audit in order
to ascertain where energy savings
could be made. The results
identified that the fixed speed
compressor was operating
unloaded for 30% of its duty cycle.
John Aldridge comments;
"Compressor Care (N.Wales)
proposed installing a Boge SF 100-
2 frequency controlled screw
compressor to become the main
compressed air provider with the
existing Boge S 75 fixed speed
screw compressor becoming the
back-up unit.
"The Boge S 75 was installed
over four years ago and in that time
had proved to be very reliable so
we had no qualms in opting for an
additional Boge screw compressor."
Boge SF series frequency
controlled screw compressors
work strictly in accordance with the
compressed air demand by
producing the exact volume of
compressed air at the pressure
required. Frequency control
minimises idling time and evens
out air demand fluctuations.
Henrob opted to purchase the
new energy efficient equipment
with an interest free 'energyefficiency'
loan from the Carbon
Trust. These loans are aimed at
SME's within the UK who are
making a commitment to save
energy by investing in energy
efficient technologies to replace
dated existing equipment.
John Aldridge concludes; "The
upgraded compressed air system
has already created a 16% reduction
in the Companies energy bill.
Moreover we expect to see a £6,000
per annum energy cost saving!" More articles from Boge Compressors Ltd: |
