Hot air generator- THERMAIR
Hot air generators in a shell and tube design are highly efficient systems that provide clean and controlled hot air for various industrial processes.Thermair is our versatile solution, often called a hot air generator or hot air heater in various industries. The hot air generator consists of a robust outer shell housing a series of tubes. The fuel is burnt in the furnace and the flue gases are passed inside the tubes. The process air is passed over the tubes to achieve a controlled heating at a desired temperature.
Thermair is a smoke tube design, where flue gases pass through tubes and hot air flows over them for efficient heat transfer. The ventilation blower fitted alongside circulates fresh air over the combustion chamber and the set of smoke tubes, the fresh air travels through its pathway along the hot smoke tubes for the desired heat transfer. In oil-fired or gas-fired options, an imported mono-block type fully automatic burner is provided for combustion of fuel.
Our Hot air generators are ideal for applications like drying, curing, and heating in industries. Their durable construction, easy operation, and minimal maintenance requirements make them a reliable solution for continuous hot air generation.

FAQs related to Hot air generators:
A hot air generator is a device that produces hot air for industrial applications by burning solid fuel or oil & gas. It transfers heat to air either directly or indirectly, depending on the design.
Our Thermair model is a durable solution for indirect heating requirements for process heating.
Direct fired hot air generators allow combustion gases to mix with the air, while indirect models use a heat exchanger to keep combustion gases separate—ideal for sensitive applications such as food processing requirements like drying or dehydration.
Yes, in some processes where only hot air is needed, an air heater boiler or hot air heater can replace conventional steam systems for better efficiency.
We offer models like wood fired, coal fired, gas fired, LPG, and solid fuel fired hot air generators based on your energy source availability.
