Kirloskar 117 kVA Silent Generator

The Kirloskar Optiprime 117 is a premier 117 kVA diesel generator (rated at 93.6 kW with a 0.8 power factor) engineered specifically for the Indian industrial and commercial sectors. As Indian businesses face frequent load shedding from providers like MSEDCL, BESCOM, and TNEB, this three-phase 415V generator provides a seamless transition during power failures. Powered by a 6.6L water-cooled Kirloskar HA694 engine running at 1500 RPM, it ensures high-torque performance for heavy inductive loads like HVAC systems, lifts, and industrial motors. The unit is fully CPCB-II compliant, adhering to India's strict emission norms, and features a silent canopy that keeps noise levels below 75 dB(A) at 1 metre, crucial for RWA and urban compliance. Key safety features include low oil shutdown, earth leakage protection, and over-temperature sensors, all monitored via a sophisticated digital control panel with remote monitoring capabilities. For Indian buyers, the choice of a 117 kVA Kirloskar unit offers a significant advantage over battery inverters which cannot support heavy 3-phase equipment. With a 250L fuel tank and a 12-hour full-load runtime, it bridges the gap during long-duration outages in Tier-2 and Tier-3 cities where grid stability remains a challenge. The 2-year or 5000-hour warranty further reinforces the brand's 60-year legacy of trust in the Indian power backup landscape.

Quick Answer

Yes, given the 2-year/5000-hour warranty and Kirloskar’s extensive service network across India, the Optiprime 117 offers high resale value and low downtime. While the initial investment is higher than unbranded local assemblies, the fuel efficiency and CPCB-II compliance make it a more cost-effective and legally secure solution for Indian businesses long-term.

Emergency backup for a 50-bed multi-specialty hospital in a Tier-2 city.
Primary power source for a highway petrol pump and attached QSR restaurant.
Continuous power supply for a CNC machining workshop during peak load shedding hours.

In the Indian context, a silent generator is almost always worth the investment over an open-frame model. Most municipal corporations and pollution control boards prohibit open-frame diesel engines in populated areas. The silent canopy not only ensures legal compliance but also protects the engine from India's harsh monsoon rains and dust, extending the lifespan of the alternator.

✓ Who Should Buy

  • This generator is primarily purchased by Indian industrial units, medium-sized factories, healthcare facilities (hospitals and diagnostic centres), and large retail showrooms. It is also a preferred choice for residential welfare associations (RWAs) in multi-storey apartments to power common area lifts and water pumps during grid failures.

✕ 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 117 is a heavy-duty 93.6 kW (117 kVA) silent diesel generator designed to tackle the demanding power deficit in the Indian market. Built for reliability during peak summer demand failures and scheduled DISCOM outages, this CPCB-II compliant DG set features a robust Kirloskar HA694 6-cylinder engine. With a 250-litre fuel tank providing up to 24 hours of runtime at half load, it serves as an indispensable backup for factories, large retail outlets, and commercial complexes across India. Its silent canopy design ensures it meets the strict noise regulations of 75 dB(A) at 1 metre, making it suitable for urban residential societies and commercial zones.

Engineering Analysis
The Optiprime 117 is powered by the legendary Kirloskar HA694 engine, a 4-stroke, turbocharged, 6-cylinder workhorse with a 6.6-litre displacement. Operating at a stable 1500 RPM, the engine is water-cooled to survive the extreme 45°C+ Indian summers. The electrical system utilizes a brushless alternator with Class H insulation and copper winding for maximum conductivity and thermal resistance. The inclusion of an electronic governor ensures precise frequency control, while the AVR (Automatic Voltage Regulator) maintains a steady 415V output, protecting sensitive industrial electronics from voltage spikes. The 84% efficiency rating is class-leading for a 125 kVA-class range generator.
