| No cooling system blockagewith closed loop cooling The closed cooling system provides greatly improved cooling even when the motor is not submerged. The heat transfer of the motor is guaranteed, even with pumping media which tends to bake on the motors and cover it with a heavy heat insulation layer Summary of benefits ■ Better serviceability as result of no contamination of the cooling circuit. ■ Better cooling, when using VFD at low speed. ■ Lower powerconsumption in comparison to open system. ■ No blockage by baking materials like clay. ■ No build upof micro organism or mussels inside cooling jacket. ■ Noventilation problems, especiallywhenverticallydryinstalled. |
