Significant savings for Midlands brewery
May 1st 2007 Alarge proportion of
gearboxes in the UK food
and drink industry are
helical worm units, with average
efficiencies of about 75%. Retrofitting
Flender helical bevel geared
motors, with typical efficiencies of
96%, can provide efficiency
improvements of up to 28%,
according to Siemens Automation
& Drives.
Significant energy savings were
made at a large Midlands brewery
following the installation of Flender
Motox helical bevel geared motors.
The brewery's conveyor drive
featured non-Flender helical worm
drives, each using 1.5kw at 82rpm,
with an overall drive efficiency of
just 59%. Actual monitored power
consumption was 1.1kW.
When a Flender helical bevel
drive with an energy efficient (eff1)
motor was fitted, providing 1.5kw
at 82rpm, drive efficiency improved
to 81% and the actual monitored
power consumption dropped to
.48kW. New helical bevel units were
fitted following this result, with
motors achieving .55kW
consumption.
Overall savings were calculated
assuming an energy charge of
6p/kWh, and equated to
£562/annum per unit. At the
brewery, 42 Flender Motox units
were installed. calculating typical
energy charges at 6p/kwh, this
equated to almost £24 000 in
savings per annum More articles from Siemens Automation & Drives: |
