Cummins 200 kVA Silent Diesel Generator

The Cummins C200D6 is a premium 200 kVA silent diesel generator engineered for mission-critical standby power in India. This 3-phase industrial-grade machine provides a rated output of 200 kVA (approx. 160 kW at 0.8 PF) and a maximum output of 220 kVA. It is powered by a 6-cylinder, 6.7L turbocharged QS6.7-G5 engine, ensuring high efficiency and low maintenance for continuous duty applications. Designed for the Indian climate, it features a water-cooled system and a 250L fuel tank that offers up to 9.4 hours of runtime at full load (26.5 L/hr). The unit includes a silent canopy to keep noise levels at 75 dB, making it suitable for hospitals, high-rise apartments, and commercial centers. With features like auto-start, electronic governing for precise voltage, and comprehensive safety protections including low oil shutdown and earth leakage, it bridges the gap during DISCOM outages. This generator is a superior investment compared to battery-only solutions for large loads such as HVAC systems, elevators, and industrial machinery, backed by a 2-year Cummins warranty.

Quick Answer

Given the rising frequency of scheduled power cuts and the 'peak demand' surcharges in India, the Cummins C200D6 is a high-value investment. Its durability and the extensive Cummins service network in India ensure a higher resale value and lower total cost of ownership compared to unbranded alternatives.

✓Emergency backup for a 50-bed multi-specialty hospital in Pune during monsoon outages.
✓Continuous power supply for a textile factory in Surat to prevent production loss.
✓Standby power for a data center in Bangalore to ensure zero data loss during grid switching.

In urban India, a silent canopy generator like the C200D6 is the only viable option due to strict RWA rules and municipal noise pollution laws. Open-frame models are cheaper but are restricted to remote industrial sites or rural areas where noise won't affect the local population.

✓ Who Should Buy

  • •This unit is typically purchased by industrial manufacturers, large healthcare facilities, data centers, and luxury residential complexes in India that require unfailing power. It is designed for those who cannot afford even a few minutes of downtime, especially where MSEDCL or other state DISCOM grids are unreliable.

✕ Who Should Avoid

  • •Spaces or usage requirements exceeding residential rated capacity.
  • •Installations prioritizing minimum capital expenditure over high-efficiency performance.
  • •Unstable grid conditions exceeding the functional threshold of Standard power cycle.
  • •Environments incompatible with generators physical and thermal dissipation specs.
Product Overview
The Cummins C200D6 is a heavy-duty 200 kVA diesel generator designed to tackle the most demanding power-cut scenarios in India. Powered by the reliable QS6.7-G5 engine, this 3-phase standby generator delivers 220 kVA max power, making it a cornerstone for industrial units, hospitals, and large commercial complexes facing MSEDCL or BESCOM load shedding. Housed in a silent canopy, it maintains a strict 75 dB noise level, ensuring compliance with residential and urban zone noise norms. With its 6.7L displacement and 4-cycle turbocharged engine, it provides a robust alternative to unstable grid power and gaps left by standard UPS systems during summer peak failures.

Engineering Analysis
At the core of the C200D6 is the QS6.7-G5 engine, a 6.7-liter turbocharged powerhouse operating at 1800 RPM. This 6-cylinder configuration offers smoother torque delivery compared to smaller engines, crucial for starting heavy inductive loads like 3-phase motors or central air conditioning. The brushless alternator with Class H insulation and AVR technology ensures a 92% efficiency rating, minimizing harmonic distortion for sensitive electronics. While the unit is rated for 60Hz/480V (ideal for SEZs and specialized industrial equipment), its build quality mirrors the ruggedness required for the Indian grid's high ambient temperatures and dusty conditions. The silent canopy is not just for noise; it provides a weather-resistant steel shell that protects the internal electrical components from monsoon humidity.
