Silent Generator is an enclosed diesel power generation system for standby and prime power applications where operating noise, outdoor exposure, and equipment access need to be controlled in one package.
Soundproof Canopy Design
Acoustic Insulation
High-density acoustic foam and sound-absorbing lining are fitted to the canopy walls and engine compartment to reduce airborne engine and mechanical noise.
Acoustic Air Channels
Labyrinth-type air channels and acoustic louvers are installed at the intake and discharge openings to reduce direct sound transmission through the ventilation paths.
Exhaust Silencing
An industrial-grade muffler and enclosed exhaust pipe reduce combustion and exhaust noise before discharge.
Vibration Isolation
Rubber or spring anti-vibration mounts are installed between the engine, alternator, and base frame to limit vibration transfer.

Outdoor Protection
Rain Protection
The canopy uses a sloped steel roof, covered air openings, and rain shields to reduce direct water entry into the generator compartment.
Dust Protection
Sealed electrical cabinets, covered service openings, and protected ventilation paths reduce direct dust exposure to internal components.
Corrosion Protection
The steel canopy is treated with surface preparation and protective powder or spray coating for outdoor installation.
Cooling & Ventilation
Radiator Cooling
A copper-aluminum radiator core and belt-driven cooling fan remove heat from the engine coolant during operation.
Airflow Control
Steel intake louvers and radiator discharge ducts create separate fresh-air intake and hot-air exhaust paths.
Hot-Air Discharge
The radiator outlet is directly connected to the canopy discharge opening to prevent heated air from circulating back into the engine compartment.
Engine & Generator Configuration
Engine Selection
Cummins, Perkins, Weichai, Yuchai, SDEC, and other mainstream diesel engines are available for different generator ratings and operating requirements.
Alternator Selection
Stamford, Leroy-Somer, Marathon, Engga, and other alternator brands can be matched to the required voltage, frequency, and output.
Controller Selection
Deep Sea, ComAp, and SmartGen controllers are available for manual, automatic, AMF, and synchronization applications.
Electrical Configuration
Output can be configured from 25–2000 kVA, with 110V / 220V / 380V / 400V / 415V / 480V, single-phase or three-phase, and 50/60 Hz options.
Automatic Backup System
ATS Integration
An automatic transfer switch can monitor utility power and send a start signal to the generator when the mains supply fails.
Automatic Recovery
After utility power is restored, the ATS transfers the load back to the mains and initiates the generator shutdown sequence.
Operating Monitoring
The controller displays engine speed, voltage, frequency, running hours, and active alarms for daily operation and maintenance.
Applications
Residential & Urban Power
Used for residential buildings, villas, shops, and urban facilities where generator noise needs to be controlled.
Healthcare & Hospitality
Designed for hospitals, clinics, hotels, and similar facilities requiring backup power with reduced operating noise.
Commercial Facilities
Used for offices, retail buildings, restaurants, and commercial complexes requiring enclosed standby power equipment.
Construction & Infrastructure
Applied to telecom sites, urban construction projects, infrastructure works, and temporary power installations.
Industrial & Remote Sites
Used in factories, industrial parks, mining sites, and remote facilities requiring enclosed prime or standby power.

FAQ
Q: What is the difference between a silent generator and an open-frame generator?
A: A silent generator uses an enclosed canopy with acoustic treatment, while an open-frame generator leaves the engine and alternator exposed. The enclosed design is intended for installations where operating noise and equipment exposure need to be controlled.
Q: How is the noise level of a silent generator specified?
A: Noise performance is normally specified as sound pressure level in dB(A) together with a defined measurement distance. The measurement distance should always be stated when comparing generator models.
Q: How much space is needed around a silent generator?
A: The installation needs sufficient clearance around air intake, radiator discharge, exhaust, doors, and maintenance areas. This prevents restricted airflow and allows technicians to access service components.
Q: Can a silent generator be installed in a residential or commercial area?
A: Yes. Its enclosed acoustic design makes it suitable for locations where generator noise is a project consideration, including residential developments, commercial buildings, hotels, and urban facilities.
Q: What should I check when comparing silent generator suppliers?
A: Compare the actual generator output, engine and alternator brands, noise measurement method, canopy construction, controller, testing records, warranty terms, spare-parts support, and technical documentation.
Q: Does the silent canopy make routine maintenance more difficult?
A: The canopy can be equipped with large service doors and removable panels so technicians can reach the engine, filters, battery, controller, and other routine maintenance points without removing the complete enclosure.
Q: What documents should I request before purchasing a silent generator?
A: Request the technical datasheet, generator test report, wiring diagram, operation and maintenance manual, engine and alternator documentation, packing list, and applicable conformity documents.
Q: Can the same silent generator be used for prime and standby power?
A: Generator ratings are available for both prime and standby applications, but the selected rating must correspond to the intended duty cycle and operating mode.
Q: Can silent generators be supplied as mobile units?
A: Yes. Trailer-mounted configurations can be supplied with two-wheel or four-wheel chassis, braking systems, jacks, and support legs for temporary or mobile power applications.
Q: What spare parts should be ordered with a silent generator?
A: Common service parts include fuel filters, oil filters, air filters, belts, coolant-related components, fuses, and other engine-specific maintenance parts. Ordering critical service parts with the generator helps reduce future maintenance delays.
