Non-Recirculating Indirect Process Air Heater (IAH-NR)
Home / Indirect Fired Air Heaters / Non- Recirculating
Clean, High-Temperature Process Air Without Recirculation
Smaller and more customizable than our IAH-R models, Stelter & Brinck’s non-recirculating indirect fired air heaters (IAH-NR) deliver clean, combustion-free process air for your operation.
Our IAH-NR units provide a cost-effective, medium-efficiency option for indirect heating applications where process purity is critical. Each heater is factory-built with a custom designed, full-welded integral tubular heat exchanger, burner and combustion system, and complete control package. Standard models are available with process air outlet temperatures up to 900°F—higher temperature designs are available upon request.
To meet your plant’s specific needs, these indirect process air heaters can be configured:
- For local or remote control
- Installed in horizontal or vertical orientation
- Designed for indoor or outdoor service
- High pressure/ high temperature arrangements available
