A soundless diesel generator also referred to as a highly silent diesel generator has been designed to operate with minimal noise emission. It uses the latest noise mitigation techniques including but not limited to multi-layer insulation casing with custom mufflers, and vibration dampening parts. This kind of generator is mostly used in regions where noise level regulations are very stringent. They are not only in compliance with the noise emission limits, but also leverage on the reliability as well as the high power output capability of diesel generators. The level of generated efficiency and silence needs routine maintenance of the muffler, engine, cooling system and anti-vibration chamber to sustain.
