Kirloskar 900 kVA Silent Diesel Generator

The Kirloskar KI-900 is a powerhouse 900 kVA industrial diesel generator designed to tackle India's most demanding power challenges. With a rated power of 720 kW and a 0.8 power factor, this three-phase (415V) unit is ideal for large-scale industrial plants, hospitals, and high-rise commercial complexes facing frequent load shedding or summer peak demand failures from DISCOMs like MSEDCL, BESCOM, or TNEB. Featuring a 6-cylinder, 10.38L turbocharged water-cooled engine, it delivers high efficiency of 85% at a steady 1500 RPM. As a CPCB-II compliant silent generator, it operates at a noise level of 75 dB(A) at 1 meter, making it suitable for urban industrial zones and sensitive commercial areas following RWA guidelines. The massive 1100-liter fuel tank ensures approximately 7.5 hours of continuous runtime at 100% load with a consumption of 145 L/hr, or up to 15 hours at half load. Safety is paramount with earth leakage, over-temperature, fuel cut-off, and overload protection integrated into a digital control panel. For Indian businesses requiring high uptime, the auto-start, remote monitoring, and cloud connectivity features eliminate the downtime typical of manual switchovers or UPS handover gaps. Backed by Kirloskar’s 60-year legacy of manufacturing in India and a comprehensive 2-year or 5000-hour warranty, this DG set is a reliable investment compared to solar-battery hybrids that may struggle with heavy three-phase inductive loads like HVAC and large motors. The brushless alternator with Class H insulation and AVR technology ensures a stable voltage of 415V at 50Hz, protecting sensitive electronic equipment from surges.

Quick Answer

Given the potential for massive revenue loss during a grid failure, the KI-900 is a high-value investment. While initial costs are higher than smaller units, the reliability of a Kirloskar engine, CPCB-II compliance, and the ability to handle large three-phase loads make it more dependable than inverter-battery stacks or solar panels for industrial-grade requirements.

✓Hospital life-support and OT backup
✓Textile mill continuous production
✓Data center server cooling and uptime

In India, a silent canopy is almost always mandatory for commercial and urban installations to comply with environmental noise pollution rules. While open-frame models are cheaper and used in isolated mining or rural construction sites, the silent KI-900 provides the necessary weather protection and noise dampening required for high-density areas.

✓ Who Should Buy

  • •This generator is primarily purchased by industrial plant owners, large hospitals, high-rise residential complexes (for lift and common area backup), and data centers across India who cannot afford even a second of power interruption. It is also a staple for large-scale infrastructure projects and construction firms needing mobile yet powerful site energy.

✕ 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 Kirloskar KI-900 is a premier industrial-grade diesel generator set (DG set) engineered for the rigorous power demands of the Indian market. Delivering a robust 720 kW (900 kVA) output, this three-phase system is designed to combat frequent grid instability and scheduled load shedding in Tier-2 and Tier-3 industrial zones. Powered by a 10.38L turbocharged Kirloskar engine, it offers 85% efficiency and full CPCB-II emission compliance. With its silent canopy design reducing noise to 75 dB(A), it is the gold standard for commercial complexes, manufacturing units, and large-scale emergency backup infrastructure requiring a seamless transition from DISCOM supply to internal power.
