Clean, Efficient Industrial Process Air Heating

Indirect Fired Air Heaters are used when the process requires separation of the combustion gases from the process air stream. They are commonly used for applications involving chemically sensitive products, including food, grain, pharmaceutical and industrial drying processes.

S&B indirect air heaters are available in three configurations:

• Recirculating Indirect Air Heater- Available with USDA Dairy Compliance options
• Non-Recirculating Indirect Fired Air Heater
• Straight-Through Indirect Air Heater

Each heater can be configured for low-emissions operation. Standard designs are available for process air outlet temperatures up to 900°F; higher-temperature configurations are available upon request and based on specified operating conditions.

Indirect fired process air heaters are commonly used with spray dryers, fluid bed dryers, rotary dryers, kilns, spray booths, chemical dryers, flash dryers, kiln furnaces, ovens and other industrial heating and drying equipment.
