With the improvement of living standards, building a healthy and green life is becoming a benchmark that leads consumers to be consumed correctly. In order to ease increasingly power tense situation, diesel generating set, as the emergency power supply of supply network, are commonly used in some special places where are strict with environmental noise such as hospitals, hotels, high-end living areas and large shopping malls and so on. This is because silent type generator sets have many advantages like low noise, tight structure and small occupying space etc..

Moreover, in addition to have all functions of diesel-electric sets, engine generator set have other excellent characteristics like being small in size, easy to assemble and corrosion resisting. There are more in detail as following:

1. It can reduce noise to below 70dbA by the silent type enclosure which is produced in accordance with noise reduction standards of ISO3744.

2. The overall structure is so compact that takes up a small space. And the case is used steel plate to split joint. As a result, it is easy to assemble and remove. On the other hand, the areas of intake and outtake within the silent type generator sets are combined into an integrated structure which is better to the elimination of high-frequency noise.

3. The new multichannel ventilation installation can ensure that generator sets always work in a suitable environment temperature.

4. The super high-capacity fuel tank of engine base can be available for 8-12 hours of continuous operation so that ensures the adequate dynamic performance of generator sets.

5. The special material of noise reduction with high-performance anti-rust paint can denoise and keep rain out at the same time.

6. Large complex silencer is matching up with the efficient anti-vibration measures, resulting in balanced operation of generator sets.

7. There is a scientific observation window and EMERGENCY STOP button so as to observe the operation of generator sets and avoid damage of sets in case of an emergency.

Generally speaking, the noise source of silent diesel generator is produced by vibration and operation of machinery. However, silent type generator sets are used some scientific measures like vibration isolation, sound deadening, sound insulation and sound absorption etc. so that make noise greatly reduced which can be reached up 30dBA. The noise reduction facilities of silent type generator sets include following parts:

1. Vibration isolation facility: the bridges among diesel-electric sets are used some high-performance shock absorbers in order to reduce the noise.

2. Sound insulation enclosure: this enclosure is made from four or five layers of sound absorbing material which can change propagation direction of some sound wave so that make sound wave energy weakened.

3. Silencers of intake and outtake: this silencer is called labyrinth silencer which is usually made from three layers of sound absorbing material, resulting in reducing noise from movement of air.
