Kirloskar 20 kVA Silent Diesel Generator

The Kirloskar KG1-20WS is a premium 20 kVA silent diesel generator designed to tackle India's persistent power-cut challenges across industrial and commercial sectors. With a rated power of 20 kVA (approx. 16 kW at 0.8 PF) and a maximum output of 22 kVA, this three-phase (415V) power backup solution is engineered for continuous duty. It features a robust 1.24L water-cooled diesel engine operating at 1500 RPM, ensuring stability during peak summer demand when grids like MSEDCL or BESCOM often face failures. This model is CPCB-IV+ emission compliant, the latest Indian standard for environmental safety, making it a future-proof investment for any business. The unit is housed in a high-quality silent canopy that limits noise levels to 75 dB, adhering to strict pollution control board norms for residential and commercial zones. For fuel efficiency, it consumes 5.0 liters per hour at full load, providing an 11-hour runtime on a 55L tank. Safety is comprehensive, featuring low oil shutdown, overload protection, earth leakage, and an emergency stop button. Whether for a medical clinic, petrol station, or small factory, the KG1-20WS ensures a reliable bridge over the UPS handover gap. Backed by a 2-year warranty on both the engine and alternator, Kirloskar’s 60-year legacy provides the reliability required for critical Indian infrastructure.

Quick Answer

Yes, given the volatility of the Indian grid and the rising cost of petrol, this diesel-powered Kirloskar unit offers a lower total cost of ownership over 5 years. The CPCB-IV+ compliance ensures it won't be rendered obsolete by upcoming environmental regulations, protecting the buyer's investment.

✓Backup for 24/7 diagnostic centers and small hospitals for life-saving equipment.
✓Continuous power for petrol stations to run fuel dispensers and office lights during outages.
✓Standard power source for construction sites requiring three-phase power for mixers and vibrators.

In India, the silent canopy (75 dB) is mandatory for any installation near residential areas or office complexes to comply with noise pollution laws. While open-frame generators are cheaper, they are restricted to isolated industrial zones; the KG1-20WS silent canopy offers the versatility to be installed anywhere without risking complaints from neighbors or RWAs.

✓ Who Should Buy

  • •This generator is primarily purchased by SMEs, medical clinics, petrol pump owners, and medium-scale industrial units in India. It is also favored by real estate managers for apartment lift backups and by event organizers who need a reliable, mobile-silent power source that meets CPCB norms.

✕ 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 KG1-20WS is a heavy-duty 20 kVA silent diesel generator designed for the rigorous power demands of the Indian market. Operating at 415V three-phase, it is powered by a 2-cylinder, water-cooled engine that complies with the latest CPCB-IV+ emission norms. With a rated power of 16 kW (20 kVA at 0.8 PF), this unit bridges the gap during frequent DISCOM load shedding, providing seamless backup for industrial machinery, hospitals, and commercial complexes. Its robust steel canopy ensures a noise level of ≤75 dB, making it suitable for noise-sensitive urban environments.

Engineering Analysis
The KG1-20WS employs a mechanical governor for precise engine speed control at 1500 RPM, which is vital for maintaining a consistent 50Hz frequency under variable loads. The brushless alternator utilizes Automatic Voltage Regulation (AVR) and Class H insulation with 100% copper winding to handle the thermal stresses typical of Indian summers. The 2-cylinder 1.24L engine layout provides a balance between compact dimensions and high torque, while the water-cooling system ensures the unit can run for extended periods without derating, unlike air-cooled alternatives in the same kVA bracket.
