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
