1. Lowest Melting Cost, cause of highest electrical efficiency so consumes less KWH/TON of melting
2. Lowest Auxillaries Running Cost, cause of Highest thermal efficiency so melting cost in totality is reduced
3. Lowest input KVA required, cause of the best average power factor of the furnace is 0.98 to 0.99 in actual running conditions, so better utilization of Power unit
4. Reduced fixed cost/ variable cost, cause of excellent lining life at lowest power consumption, so an over all better utilizations of productive hours increase due to less patching & sintering.
5. Excellent Reliability, cause of structured and simples design of the furnace reduces the break-down.
6. Lowest investment cost,
(A) Cause of Compact furnace design, covers less
floor space area compare to others.
(B) Cause of reasonable furnace price
