TI Automotive of Flint makes HDPE
plastic fuel tanks for global automakers.

Looking to cut bills, the
company asked ABB Drives Alliance
member Central Group to investigate
where energy use could be reduced.

With production based on blow
moulding, the plant uses a lot of
compressed air. Central Group
installed a 75kW ABB standard drive
on the compressor, which previously
had a fixed speed unit. Running the
motor at half speed, the drive cut
consumption from 75 to 45kW.

Installing 11kW ABB standard
drives on three pumps produced a
30% saving, cutting power demand
from 11 to 7kW.

In production 24h/day, a
granulator was only actually working
for 10sec in each minute. Running
the granulator motor at the same
fixed speed, an ABB industrial drive
reduced its power consumption from
42 to 15kW.

Overall, the plant is saving around
£2000 a month on its energy bill.
