Diesel fueled hot air generators are comprised of the combustion area, which is constructed from stainless steel the gas pipes and the outer casing. The exhaust gases travel through the we offer sabo diesel burner. Pipe system, over several directions before they are expelled through the smoke stack into the atmosphere. The warmed air does not come in contact with the exhaust gases but rather it circulates around the pipes and the combustion area, successfully preheating it and achieving 90% efficiency.
