Kirloskar

135 kVA Silent Diesel Generator

The Kirloskar KG1-135WS is a heavy-duty 135 kVA silent diesel generator designed to tackle the demanding power infrastructure of India. As DISCOMs face peak summer loads and Tier-2/3 cities experience scheduled outages, this DG set provides an unwavering 135 kVA (approx. 108 kW at 0.8 PF) output. Engineered with a Kirloskar HA694 TCI G2 water-cooled engine, it operates at 1500 RPM and is fully compliant with the latest CPCB-IV+ emission norms, ensuring it meets strict NGT regulations for urban installations. This three-phase (415V) industrial-grade generator is housed in a premium soundproof silent canopy, limiting noise to ≤75 dB at one meter, making it suitable for noise-sensitive zones. With a massive 230-liter fuel tank and a consumption rate of 28.8 L/hr at full load, it offers 8 hours of continuous backup for critical industrial machinery or large commercial HVAC systems. Safety is paramount with features like low oil shutdown, earth leakage protection, over-temperature sensors, and an emergency stop button. Whether for a large manufacturing plant, a retail mall, or a healthcare facility, the KG1-135WS offers the reliability of Kirloskar’s 60-year-old Indian brand legacy. It bridges the critical UPS handover gaps, preventing downtime in server rooms and production lines. Compared to older non-compliant models, this CPCB-IV+ unit ensures lower operational costs, higher fuel efficiency, and a reduced carbon footprint, making it a future-proof investment for Indian conditions.

Quick Answer

Yes, it is a highly worthy investment. While the upfront cost is higher than an inverter, no battery system can sustain 108 kW of industrial load for 8-13 hours. Kirloskar's massive service network in India ensures that spare parts and technicians are available even in remote locations, minimizing downtime.

Seamless backup for a 50-bed hospital operating ICUs and surgical theaters during summer peak cuts.
Providing continuous three-phase power to a plastic injection molding factory during MSEDCL scheduled load shedding.
Reliable power source for a multi-storey retail mall in a Tier-3 city to keep elevators and lighting functional.

In India, silent canopy generators are now the industry standard for any commercial or residential zone due to CPCB noise limits of 75 dB. While open-frame generators are cheaper, they are restricted to isolated industrial zones; the KG1-135WS silent canopy allows for installation near office blocks or hospitals without violating noise pollution laws.

✓ Who Should Buy

  • This generator is typically purchased by owners of medium-sized factories, cold storage units, large retail malls, and multi-specialty hospitals in India. It is also a preferred choice for construction sites and real estate developers providing common area power backup for high-rise residential societies.

✕ 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.

Engineering Analysis
The KG1-135WS utilizes the HA694 TCI G2 engine, a 4.15L displacement 4-cylinder beast designed for 1500 RPM stability. The water-cooling system is specifically tuned for the high ambient temperatures of Indian summers, preventing thermal derating during peak usage. The alternator is a brushless, copper-wound unit with Class H insulation, ensuring it can handle the reactive loads of three-phase motors and industrial equipment. With a 91% efficiency rating and AVR technology, it delivers a clean sine wave (415V, 50Hz) that protects sensitive electronics from voltage surges.
