At Inmesol we have just manufactured a new super-soundproof 915 kVA PRP and 1010 kVA LTP container model specifically designed to operate in an emergency at a mechanical-biological treatment plant located in the county of Istria in the Republic of Croatia.
Unlike the serial generator sets, this equipment has two external silent modules, one for admission and another for expulsion, which means we have significantly reduced sound emissions, lowering them from 78 dB(A) at 7 m of sound pressure in the standard models in normal conditions to 71 dB(A) at 7m.
In order to lower the sound emissions in the IT-1010, we implemented the “splitter” silencer system: the airflow is separated into fine channels, which we then covered and insulated with absorbent material. This means the sound waves are forced to split through the various ducts and progressively lose energy as they encounter the absorbent material until they are notably reduced upon exiting the container. The result is a super-silent generator with low acoustic pressure and emission.
The main sources of sound emissions which have to be considered when soundproofing a generator set are those caused by the mechanical forces, motor combustion, the fan, the motor exhaust and the alternator, as well as those created by vibrations in different parts of the machine.
The new model is already available for purchase and adds to our wide range of Inmesol stand-by generator sets, thus satisfying the high expectations of a market sector which demands highly advanced technology and environmentally friendly equipment.
