Solutions that effectively pay for themselves.
Saftronics recently completed a
project were the sole purpose of
the project outcome was energy
saving, while still obtaining
optimal operating time. Our
clients’ plant is a plastic
manufacturing facility which by
its nature is a very energy
demanding process, hence the
need for our expertise.
With the help of a power
analyser, power quality issues
were addressed. And our
Saftronics “Chief” range of VFD’s
were installed on 5 of the 17
plastic injection moulding
machines, by doing this the VFD
allows the motor to run at a
lower frequency when less power
is required (when the load is
lower) and ramps the motor up
when demand increases (when
the load increases).The end result
was a reliable retrofit to our
clients machines and a clear
energy saving was recorded as
depicted in the adjacent graphs.
