Content of Proposal
Background
- Current motor wide blower don’t have inverter
- Current pressure condition is still high , we have possibility TCR electricity consumption by installation inverter.
- We already install on line 31 as pilot project.
Proposal
- We want replication no. 31 activity to another line .
- This year we want to replication inverter activity to machine No. 26,29 and 30.
Effect
– Reduce electricity consumption estimasi 297 mRp/years ( total 3 line)
– ROI : 1.5 Years
Schedule
- Construction : September 2024
Investment cost
- 465 Mill Rp (In budget 2023  500 Mill Rp.)

Background
- Current pressure condition is still high , we have possibility TCR electricity consumption by
installation inverter and use 40 Hz condition.
- We already install on line 31 as pilot project , we want to expand this activity.
It depend on trial condition. However, in current, it’s still high pressure condition.
So, even though reduction frequency, we’ll be able to convey product web.

Based on our trial on KI -31, Converting still can convey with static pressure 17
kPa, then our KI-30 data is around 25 kPa , based on this data we can reduce
the static pressure condition by doing same activity on KI -31.
Theorytical static pressure and kwh
PSTATIC40HZ = (40 HZ/50 HZ)2 * PSTATIC50HZ
W40HZ =(40 HZ/50 HZ)3 * W40HZ
