Replacement of 250 KVA DG Set at P2 Site Mahakalpada

SITC OF Lowest life cycle cost Diesel Generator set 250 kva for comparison of operating economy, reliability and long life. When all cost factors like initial purchase, fuel, lube oil, maintenance and overhaul are considered, the bottom line will deliver the lowest life cycle cost.

Heavy duty, durable and emission compliant with heavy duty features, bigger size camshaft, optimized turbo-matching, electrical STC Injectors and is yet compact in size with optimum power to weight ratio.

Diesel Generator powered by the reliable diesel engine meets stringent exhaust emission tests as per MOEF norms without sacrificing fuel efficiency at normal operating loads with 2 years / 5000hrs warranty for the entire generating set.

Silent Diesel Generator enclosure is so designed as to have optimum performance and serviceability over the complete operating range. The enclosure is compact with integral fuel tank and is designed for ease in maintenance. The powder coated enclosure is manufactured on latest CNC machines to ensure superior finish and durability.
