How big is a 50kW generator?
When considering a 50kw generator for your home, business, or job site, one of the most practical questions is: how much space will it take up? Understanding the physical size, weight, and installation requirements is crucial for planning, logistics, and ensuring a successful setup. While the exact dimensions can vary between models and manufacturers, a typical 50kw generator has a footprint similar to a small car, but proper planning requires considering more than just its base measurements.
Physical Dimensions and Weight
A standard 50kw generator, especially a diesel model housed in a protective canopy or silent enclosure, generally falls within the following size and weight ranges:
Length: 2500 - 3200 mm (8.2 - 10.5 feet)
Width: 900 - 1100 mm (3 - 3.6 feet)
Height: 1500 - 1800 mm (5 - 6 feet)
Weight (Open Frame): 800 - 1100 kg (1760 - 2425 lbs)
Weight (Canopy/Silent Type): 1000 - 1400 kg (2200 - 3090 lbs)
The exact size depends on several factors, including the specific engine brand, the size of the integrated fuel tank, the cooling system design, and whether it is an open or closed configuration. A silent 50kw generator will be larger and heavier than an open-frame model due to the added sound-attenuating panels and cooling systems designed for lower noise levels.
Space Required for Installation
The generator's physical size is only part of the equation. The total space you need to allocate is significantly larger to ensure safe operation, adequate ventilation, and room for maintenance.
Clearance for Airflow and Cooling: Diesel generators require a substantial amount of cool, fresh air for combustion and cooling. You should plan for at least 1 - 1.5 meters (3 - 5 feet) of clearance on all sides, with extra space in front of the radiator fan for hot air to dissipate.
Access for Maintenance: Technicians need space to access the control panel, change filters, and perform routine service. Leaving 1.5 meters (5 feet) in front of the control panel is a recommended minimum.
Overall Footprint: When including all required clearances, the total area needed for a 50kw generator installation is often twice the size of the unit itself. Always consult the manufacturer's installation manual for specific requirements.
Choosing the Right Configuration
You can select a 50kw generator in different configurations to better suit your space constraints:
Silent Canopy Enclosures: Ideal for residential areas, hospitals, or noise-sensitive environments. While bulkier, they significantly reduce operational noise.
Open Frame Models: More compact and often used in industrial settings or dedicated generator rooms where noise is less of a concern.
Trailer-Mounted Options: A highly flexible solution if permanent space is limited. A mobile 50kw generator can be stored away and moved to the exact location where power is needed.
Conclusion
A 50kw generator is a powerful piece of machinery that requires careful planning for placement and installation. Its size and weight necessitate a solid, level foundation (like a concrete pad) and significant clearance for safe and efficient operation. Proper planning for space is not just a recommendation—it is a requirement for ensuring the longevity and reliability of your power investment.
