India is one of the largest manufacturers, suppliers and exporters of diesel generators (DG) in the diesel Genset market. The market has seen significant growth in the manufacturing and industrial sectors and is expected to be a major driving factor in the coming years. Here, we’re going to take a look at the best silent diesel generator brands in India.
A diesel generator (also called Genset) is a piece of equipment built to provide an alternate power supply in case of power cuts by using a diesel-fuelled compression engine which generates alternating current. In the process, the mechanical power generated by the diesel engine rotates the motor that produces electromagnetic current. Such equipment can power a lot of electrical devices to provide alternative backup power for a limited period of time. Diesel generators usually come in distinct models and variants, which include their size, fuel capacity, power output, carbon emission, noise generation, etc.
Silent diesel generators are another variant of gensets that as the name suggests, produce less noise. This type of diesel generator is highly adopted in commercial sectors, like airports, hospitals, universities, telecom, banks, malls, hotels, restaurants, retail stores, etc., as well as in the domestic sectors, such as residences.
