Merits of new system : 1. Easy & smooth operation
2. Energy saving due to flow control by Variable Frequency Drive
2. Energy saving due to flow control by Variable Frequency Drive
Economical analysis :
Energy consumption without VFD - P1 = 40 kW
Energy consumption with VFD - P2 = 32 kW
Energy saving per day ((P1 - P2) x 24) = 192 Units
Saving per day @ Rs. 8/- Unit = Rs. 1,536/-
Saving per crushing season (Approx. 300 Days) = Rs. 4,60,800/-
