The Leeds based Microdat
Company supplies keg and
cask handling machinery in
the brewing industry. Its entry-level
filler is based around a peristaltic
pump that is speed controlled by a
Lenze SMV inverter.With IP65
enclosure, the SMV inverter is
mounted directly onto the machine.

This reduces costs and enables
operators to gain easy access to the
control keypad of the inverter.

The filler can have one or two
filling heads. Usually when filling
beer barrels one operator will use
two heads, filling one barrel while
preparing the second. Barrels are
filled to 95% by means of a timer,
and then the operator uses a hand
control to top up the barrel to 100%.

The SMV inverter drives the
peristaltic pump according to a
preset time/speed profile which is set
to avoid frothing. It is mounted to
the front of the filler without a panel
and the IP65 enclosure makes it
resistant to normal cleaning
operations with low pressure jets.

When the pump tube needs
changing, a new tube is inched
through the pump using the
integrated keypad on the inverter.
