Silent Diesel Generator
A silent diesel generator is a standard set enclosed in a weatherproof, acoustically lined steel canopy that cuts noise to roughly 70 to 75 dB(A) at 7 metres, so it can sit outdoors beside a building without disturbing people. OCALWA supplies canopied gensets from 8 to 1500 kVA, matched to your load and noise limit, from a verified ISO 9001 + CE factory.
Backup power without the noise
The acoustic canopy uses sound-absorbing foam, baffled air paths and a residential-grade silencer to drop noise sharply while still letting the radiator breathe. Lockable access doors, an emergency stop and a drip tray make it safe for install in a car park, rooftop or yard.
Inside is the same diesel engine and brushless AVR alternator as the open set, so performance and parts are identical; you gain weather protection and low noise. An automatic transfer switch makes it a true standby that starts on mains failure within seconds.

Configurations & options
Rating, engine tier, voltage and enclosure are matched to your load and grid. Send us the kW/kVA you need, whether it is prime or standby, your frequency/voltage and site conditions and we specify the right set.
Why choose a silent generator
Install near people
The acoustic canopy keeps noise low enough for hotels, hospitals, offices and residential areas where an open set would be unacceptable.
Ready for outdoors
Weatherproof and lockable, it installs outside with no plant room, saving building space and simplifying ventilation and exhaust.
True automatic standby
With an ATS it senses a mains failure and starts and takes the load within seconds, then shuts down when the grid returns, unattended.

Frequently asked questions
Typical canopied sets run around 70 to 75 dB(A) measured at 7 metres, roughly the level of normal conversation to a vacuum cleaner, versus 95 to 105 dB(A) for an open set. Exact figures depend on size and load. For hospitals or residential zones we can specify a super-silent enclosure for even lower noise.
No, when built right. The canopy has engineered air-in and air-out paths and a radiator sized for high ambient temperature, so it cools properly even in tropical heat. Tell us your maximum site temperature and we confirm the radiator and airflow rating.
Standby rating is for backup when the grid fails, used a limited number of hours a year at varying load. Prime rating is for continuous running as the main power source, at a lower rated output for the same set. If it is your only power, size on prime; if it is grid backup, size on standby. We rate it to how you will actually run it.
The set is built with your choice from several established international diesel engine brands, paired with a brushless, self-exciting alternator with AVR voltage regulation. You pick the engine tier to match your budget, fuel and local service network; we confirm the exact pairing and its rating before order.
Yes. We build 50 Hz or 60 Hz and set the voltage to your grid (for example 120/240V, 220/380V or 240/416V, single or three phase). Latin America is mostly 60 Hz. Tell us your country's frequency, voltage and phase and we configure the alternator and controller accordingly.
The set uses mainstream international engines whose oil, fuel and air filters, belts and pumps are widely stocked across Latin America. We also supply a starter spares kit and can re-order alternator parts, the controller, AVR and hoses so downtime stays short.
Yes. Beyond the bare set we supply the automatic transfer switch (ATS), starting batteries, connection cables, remote monitoring and a starter spares kit, from a verified factory (ISO 9001 + CE). OCALWA arranges container or RORO shipping and full export documentation, and regularly ships to Colombia, Venezuela, Argentina, Paraguay and the Dominican Republic, quoting FOB, CFR or CIF.
