Non-Recirculating Indirect Process Air Heater (IAH-NR)
Home / Indirect Fired Air Heaters / Non- Recirculating
Clean, High-Temperature Process Air Without Recirculation
Stelter & Brinck's non-recirculating indirect fired air heaters (IAH-NR) are packaged systems designed for applications requiring separation of combustion gases from the process air stream.
The IAH-NR is a medium-efficiency indirect heating option available in multiple configurations. Each heater includes a full-welded integral tubular heat exchanger, burner and combustion system, and control package.
Standard models are available for process air outlet temperatures up to 900°F. Higher-temperature configurations are available based on specified operating conditions.
IAH-NR systems can be configured based on specified application requirements, including:
- Local or remote control
- Horizontal or vertical orientation
- Indoor or outdoor service
- High-pressure or high-temperature operating conditions
