Sugar Industry Case in Thailand - Goodrive 5000 Series Medium Voltage Inverter

INVT GD5000 medium voltage inverter applied to Jet condenser for Vacuum Pan in the sugar factory in Thailand

The process of sugar crystallization is very important part in the whole sugar production. Normally the sugar factory use vacuum pan to heat sugar water. After the concentration of sugar water get to limited values, the sugar water go to next step. So if the vacuum pan is running, the sugar factory need use jet condenser to cooling the vacuum pan.

Normally in the sugar factory, they use pumps for jet condenser.But almost all of the pumps were directly driven by grid power. There are some disadvantages for grid power directly driving pumps:

1) The speed of running pump can’t change. Actually pumps do not always running at rated speed.

2) The pressure of water is not stable.

3) When directly start pumps, there is large impact current and impact voltage for grid power and pumps, they are no good for grid power and pumps.

Finally the customer want use inverter to drive pumps.
