Kirloskar Green silent diesel generator sets are designed to provide electrical power with a sound-attenuated enclosure for commercial, industrial and institutional applications. The range includes multiple output capacities, using liquid-cooled, four-stroke diesel engines coupled with brushless, self-excited, four-pole, three-phase AC alternators.
Available in different power ratings and configurations, these generator sets feature enclosed engine and alternator assemblies, integrated control and protection systems, and practical access for operation and maintenance. The appropriate model can be selected according to the required power output, operating duty and site conditions.
Kirloskar Green silent diesel generator sets combine a diesel engine, alternator, control system and sound-attenuated enclosure in an integrated power-generation package. The enclosure helps reduce operating noise while providing access for routine inspection and servicing.
The 60 Hz range covers standby ratings from approximately 25 kVA to 1,111 kVA, with prime power ratings from approximately 23 kVA to 1,010 kVA across the configurations shown. Three-phase, four-wire electrical output is specified, with voltage options and electrical details varying by model.
The range can support backup power requirements and continuous variable-load applications when the appropriate prime or standby rating is selected.

The model designations above identify the nominal generator families. Confirm the exact sound-attenuated model designation, enclosure configuration and availability for the required rating with AHCL Auto and Equipment Division.
Standby and Prime Power Ratings
Prime Power (PRP) is intended for supplying electrical power at variable load in place of purchased utility power. The stated rating permits a limited overload under the specified rating conditions.
Emergency Standby Power (ESP) is intended for supplying power during utility outages. Its permitted annual operating hours and average loading are limited under the specified rating conditions.
Choose the rating based on the generator’s intended operating duty. A standby-rated unit should not automatically be treated as suitable for continuous operation at the same output.
Sound-Attenuated Enclosure Features
The sound-attenuated enclosure includes design features intended to support noise reduction, protection and service access, such as:
The exact enclosure equipment may vary according to the selected rating and agreed scope.
Control System and Protection
The generator control system provides operating information and protective functions according to the controller installed. Depending on model and configuration, available monitoring and protection may include:
The controller model and the functions available on each generator rating should be confirmed during selection.
Optional Accessories
Options available for selected configurations include:
Optional accessories are not necessarily included as standard. Confirm compatibility and supply scope for the selected generator set.
Kirloskar Green silent diesel generator sets can be considered for backup or prime power applications where the required electrical rating and operating conditions are compatible.
Commercial Buildings
Backup power for offices, commercial premises and other buildings requiring a suitable standby power source.
Hotels and Hospitality
Power continuity for selected building services and operational loads during utility interruptions.
Industrial Facilities
Electrical supply for industrial sites and equipment where the required load profile matches the selected generator rating.
Healthcare and Institutional Facilities
Backup power for suitable facility loads, subject to the installation’s electrical design and applicable requirements.
Warehouses and Logistics
Power for warehouses, distribution facilities and logistics operations requiring backup or variable-load generation.
Retail and Business Premises
Standby generation for shops, retail facilities and business operations.
Infrastructure and Large Installations
Higher-capacity configurations can be evaluated for larger facilities and installations, subject to load calculations, generator synchronisation requirements and the overall electrical design.
They are diesel-powered generator sets supplied with a sound-attenuated enclosure. The package combines a diesel engine, alternator and control equipment to provide electrical power for compatible standby or prime-power applications.
The 60 Hz range includes standby ratings from approximately 25.3 kVA up to 1,111 kVA, with prime ratings from approximately 23 kVA up to 1,010 kVA. The available rating and sound-attenuated configuration depend on the selected model.
A silent generator set uses an enclosure designed to attenuate operating noise and protect enclosed components. An open generator set does not have the same sound-attenuated enclosure. Installation, ventilation, maintenance access and noise requirements should be considered when choosing between them.
Suitability depends on the selected prime or standby rating and the intended operating duty. Prime power is designed for variable-load operation under its specified conditions, while standby power is intended for utility-outage operation subject to operating limits.
Automatic starting and transfer can be configured with compatible control equipment and an automatic transfer switch. Confirm that the required controller, ATS panel and associated wiring are included in the proposed supply.
Remote monitoring and synchronisation panels are available as optional accessories for selected configurations. Suitability depends on the generator rating, controller and electrical system design.
Selection should consider the total connected load, starting currents of motors, load variation, power factor, required voltage and frequency, operating duty, site conditions and future load growth. A load assessment is recommended before confirming the generator rating.
No. Frequency, voltage, phase configuration and load compatibility must match the installation. Confirm the required electrical specifications before ordering; do not assume that every model is compatible with every site.
