Slience genset：
The noise reduction box generator set is equipped with a bottom fuel tank, an air inlet system, an air exhaust system, a highefficiency silencer, a smoke exhaust system, a unit operation door, a equipment access door, and a blinds. The exterior ismade of steel plate and the interior is made of high quality sound absorbing materials. The reasonable and environmentallyfriendly design can achieve the effect of noise reduction and shockproof, and the structure is very stable, which is convenientfor lifting and transferring, making it dificult to be damaged in a harsh environment. it can be designed as a fixed and trailermobile power station. The internal and external structural dimensions of the noise reduction box vary according to the sizeof the relevant main parts. The high performance and high standard of reasonable structure can be tailored according to thecustomer's site use and related requirements. product.
