New models feature energy efficient 'flowon- demand'
September 1st 2009 CompAir has extended its
portfolio of variable speed
compressors with the launch
of seven new models, to offer a
comprehensive range of energy
efficient rotary screw machines from
11 to 250kW.
Energy-efficiency has been
considered at every stage of the
design of the L11VS to L18VS range
to ensure machines meet the wide
variation in air demand necessary in
modern processes. Each compressor
has a variable speed drive that helps
to minimise energy use.
A compressor with a greater range
of volume output is generally more
cost efficient to operate as the
machine will automatically adjust, or
'turndown' its flow rate to the most
economic level. Each machine in the
range is engineered to offer a high
level of performance, with a volume
flow turndown that CompAir
considers to be up to 17% greater
than comparable compressors.
CompAir's L11 VS machine for
example, can continue running at as
little as 10% flow at 7 bar pressure,
for maximum flexibility of operation
and greater control over air usage.
The range comes in two frame sizes
with a noise level from 65-70 dB(A).
An AirSmart controller enables users
to monitor compressor parameters
and carry out diagnostic checks. More articles from Gardner Denver Ltd: |
