Kirloskar Optiprime 500

In the Indian industrial landscape, where DISCOMs like MSEDCL, BESCOM, or TSSPDCL often face summer peak demand failures and scheduled load shedding, the Kirloskar Optiprime 500 serves as a critical infrastructure asset. This 500 kVA (400 kW) diesel generator provides a seamless transition during outages, closing the gap that standard UPS systems cannot fill for heavy loads. Featuring a turbocharged, water-cooled DV10 engine with 10 cylinders and an 18.2 L displacement, the Optiprime 500 operates at a steady 1500 RPM. It consumes approximately 95 L/hr at 100% load, making it a commercially viable solution for long-duration backups in Tier-2 and Tier-3 cities. The unit is housed in a premium steel silent canopy, ensuring compliance with India's mandatory CPCB-II emission and noise norms. With a three-phase 415V output and 695 A current capacity, it is purpose-built for three-phase motors, lifts, and central air conditioning. Safety is paramount, featuring earth leakage protection, over-temperature sensors, and emergency stop mechanisms. The digital control panel offers remote and cloud monitoring, allowing facility managers to oversee performance via a digital interface. Backed by a 2-year or 5000-hour warranty, Kirloskar’s 60+ years of Indian engineering excellence ensures that this DG set remains the gold standard for reliable, high-output power backup in the Indian market.

Quick Answer

Yes, the Optiprime 500 is a high-value investment for Indian businesses because it combines Kirloskar’s 60-year reliability with modern cloud monitoring. Given the frequency of power cuts in Tier-2 cities and the high cost of production downtime, the generator pays for itself by preventing loss of productivity and protecting expensive three-phase equipment from voltage fluctuations.

In India, the silent canopy is mandatory for most urban and commercial installations to meet CPCB-II noise norms (≤75 dB). While open-frame generators may be cheaper, they are restricted to remote mining or construction sites; the Optiprime 500’s silent design adds significant value by allowing the unit to be placed near the main building without disturbing tenants or violating local RWA rules.

✓ Who Should Buy

  • The primary buyers of the Kirloskar Optiprime 500 are industrial factory owners, healthcare facility managers, and real estate developers managing large apartment complexes. It is also a preferred choice for data centers and infrastructure projects where high-amperage 415V three-phase power is a non-negotiable requirement for operational continuity.

✕ 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 500 is a high-capacity industrial diesel generator designed to tackle India's most demanding power challenges. Rated at 400 kW (which converts to 500 kVA at a 0.8 power factor), this three-phase powerhouse is built for continuous duty across factories, hospitals, and large commercial complexes. Engineered with the legendary Kirloskar DV10 engine, it delivers 415V output at 50Hz, ensuring compatibility with heavy industrial machinery and HVAC systems. As a CPCB-II compliant silent generator, it maintains a noise level of 75 dB(A) at 1 meter, making it suitable for installations near residential zones or urban commercial hubs where noise regulations are strictly enforced by local authorities.
