Kirloskar 35 kVA Silent Diesel Generator

The Kirloskar Freedom 35 kVA silent diesel generator is a robust solution for India's persistent power-cut challenges, ranging from scheduled DISCOM outages to summer peak demand failures. This genset provides a rated power of 28 kW and a maximum output of 31.5 kW. In the Indian market, generators are primarily rated in kVA; at a 0.8 power factor, this 35 kVA unit provides the necessary headroom for starting heavy motors and medical equipment. It features a water-cooled, 3-cylinder KOEL engine that operates at 1500 RPM, optimized for high-efficiency diesel combustion at 5.8 L/hr at full load. The unit is housed in a high-grade steel silent canopy that limits noise to ≤75 dB at 1 meter, adhering strictly to CPCB-II norms mandatory for urban installations. Safety is paramount with integrated low oil shutdown, overload protection, and earth leakage sensors. This three-phase 415V system is specifically engineered for commercial establishments, small factories, and residential apartments where three-phase motors and elevators are common. Backed by Kirloskar’s 60+ years of engineering excellence and a 2-year or 5000-hour warranty, this generator represents a reliable alternative to large-scale battery inverters that often fail to bridge the handover gap during long-duration outages. The sales package includes the genset, a 12V battery, a user manual, and a warranty card, ensuring a turnkey installation for Indian businesses seeking a professional power backup system.

Quick Answer

Given the rising cost of power outages to business productivity, the Kirloskar Freedom 35 is a high-value investment. Its KOEL engine offers superior fuel economy and longevity compared to unbranded alternatives. For Indian conditions where summer temperatures exceed 45°C, its robust water-cooled system ensures it doesn't overheat, unlike smaller air-cooled units.

Emergency backup for a 15-room hotel including kitchen equipment and elevator.
Prime power source for a remote construction site running welding machines and cranes.
Standby power for a diagnostic center with MRI or CT scan machines requiring stable 3-phase voltage.

In India, silent generators are mandatory for any area near residential dwellings or commercial hubs to comply with CPCB-II noise pollution rules. While open-frame models are cheaper and used in remote mines or fields, the silent canopy of the Freedom 35 is essential for urban businesses to avoid legal issues with local municipal corporations or RWAs.

✓ Who Should Buy

  • This model is primarily purchased by SMEs, owners of petrol pumps, cold storage facilities, and mid-sized medical clinics in India who face frequent grid instability. It is also a staple for construction sites and event managers who require a mobile yet high-capacity 3-phase power source for heavy equipment and lighting rigs.

✕ 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.
