Let’s face it, diesel generators can be extremely noisy. Sounding like a loud truck that’s parked outside with the engine continually running, is not a pleasant experience for many locations. That is where the super silent, soundproof diesel generator stands out.
A super silent diesel generator is a genset that has been enclosed to lower noise levels. They are widely used in telecommunications, hotels, entertainment venues, hospitals, shopping centres, industrial and mining enterprises. Super silent diesel generators offer better noise level performance and in places with higher restrictions on environmental noise, as a prime or standby power source.
The noise that comes from a diesel generator comes from different components of the set. Modifying these components can help to reduce noise levels, but first there needs to be an understanding of Where these noises are coming from.
Noise from the exhaust is a pulsating air flow noise with high temperature and high speed. The exhaust can be the loudest part of the generator and has numerous contributing factors including:
Mechanical noise is created within the engine due to the construction and operations, some of the areas that create these noises are:
Combustion noise is the structural vibration and noise generated by diesel oil in the combustion process. Within the cylinder, the combustion of the diesel fuel creates a lower vibration which being lower than the surrounding structure of the engine this allows the vibration to travel outwards causing the engine noises that we hear.
Cooling fan noise
Cooling fans create noise as they are spinning at high speed. The noise we hear is made:
Air intake noise
Under normal operation, diesel generators need to have enough fresh air supply, to ensure the normal operation of the engine and to also create good heat dissipation conditions for the unit. Air being drawn into a funnel over an edge will create a suction noise no different than that of a vacuum cleaner with the head removed from the pipe.
There are a number of ways that we can reduce the noise levels of a diesel generator, and these are incorporated in the super silent diesel generators.
PowerLink has a wide range of super silent diesel gensets, equipped with noise reducing features, making them suitable for noise sensitive applications. With a power output range from 10kVA to 3,250kVA, there is definitely a PowerLink solution suitable for you.
