Kirloskar 400 kVA Silent Diesel Generator

The Kirloskar Optiprime 400 is a premier 400 kVA silent diesel generator (320 kW rated power) specifically engineered for the Indian industrial and commercial landscape. Operating at a power factor of 0.8 and a standard frequency of 50Hz, this three-phase (415V) unit is essential for facilities facing unstable grid power from providers like MSEDCL, BESCOM, or TANGEDCO. This model features a massive 14.6 L, 8-cylinder turbocharged water-cooled engine, ensuring it can handle high-torque industrial motors and sensitive HVAC systems simultaneously. In India, where noise pollution norms are strict, its high-quality steel canopy limits sound to ≤75 dB(A) at 1 metre, making it CPCB-II compliant for use in residential and hospital zones. Key technical highlights include a brushless alternator with Class H insulation, a sophisticated electronic governor for precise frequency control, and a digital control panel with cloud-based remote monitoring capabilities. Safety is paramount with integrated earth leakage protection, emergency stop buttons, and low-oil shutdown mechanisms. With a fuel consumption rate of 80 L/hr at 100% load and a runtime of 16 hours at half load, it provides a sustainable solution for continuous duty operations. This generator is the gold standard for Indian businesses requiring a 400 kVA silent generator price-to-performance leader that bridges the gap between grid failures and operational uptime.

Quick Answer

Given Kirloskar's massive service network and the Optiprime 400's fuel efficiency, it is a highly worthwhile investment for Indian businesses. The 2-year warranty and the 5000-hour engine life protection offer peace of mind against the frequent voltage fluctuations and power outages that characterize the Indian electrical landscape.

Multi-speciality hospital emergency power for ICUs and OT rooms
Continuous power for plastic injection moulding factories with 24/7 shifts
Reliable backup for Tier-3 data centres requiring 100% uptime

In the Indian market, a silent canopy is no longer a luxury but a legal requirement under CPCB-II norms for most urban and semi-urban locations. While open-frame models may be cheaper, the Optiprime 400's silent canopy protects the sophisticated 8-cylinder engine from dust and monsoons while ensuring the facility remains compliant with local environmental laws.

✓ Who Should Buy

  • The primary buyers are industrial manufacturers, large-scale hospitals, data centres, and luxury high-rise apartment complexes in India that require a zero-compromise power backup solution. It is also a preferred choice for infrastructure contractors managing large highway or metro rail projects where grid power is yet to be established.

✕ 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 Optiprime 400 is a powerhouse 400 kVA (320 kW) diesel generator designed to tackle the chronic power deficit in India's industrial corridors. Engineered for heavy-duty applications, it features a turbocharged 8-cylinder Kirloskar DV8 engine, ensuring seamless performance during summer peak demand and frequent DISCOM load shedding. With a 650-litre fuel tank and CPCB-II emission compliance, it offers an eco-friendly yet robust alternative to traditional backup systems for factories, hospitals, and large commercial complexes across Tier-1 and Tier-2 cities.

Engineering Analysis
The Optiprime 400 utilizes the high-displacement Kirloskar DV8 engine platform, which is a 14.6 L turbocharged beast optimized for 1500 RPM operation. The 8-cylinder configuration provides superior balance and lower vibration compared to smaller engines in this class. Its electronic governor ensures that frequency fluctuations are kept to a minimum, which is critical for electronic loads like server rooms and medical imaging equipment. The inclusion of an AVR-equipped brushless alternator with 100% copper winding guarantees a stable 415V output, preventing damage from voltage surges commonly seen in Indian industrial grids. The cooling system is specifically rated for Indian ambient temperatures, preventing over-temp shutdowns during the harsh 45°C+ summer peaks.
