The Diesel Operated Hot Air Generator is a heating device that uses diesel as its primary fuel source. They are ideal to heat large rooms - such as portions of warehouses, construction sites - and they are usually chosen for industrial use. These generators can feature two types of combustion: direct or indirect. Diesel Operated Hot Air Generator operation is based on carrying out combustion in a home and the gases produced pass through a heat exchanger where heat transfer is carried out with the air driven by a fan.
