Typically smaller, more customizable than our IAH-R units, our non-recirculating indirect fired heaters are designed to heat your process stream, free from the by-products of combustion.

Stelter & Brinck’s non-recirculating indirect fired air heaters offer a low capital cost, medium efficiency solution to indirect heating applications. IAH-NR units are furnished complete with integral, tubular heat exchanger, burner and combustion system, and controls. These indirect process air heaters can be configured for local or remote control and can be provided in horizontal or vertical orientation, and indoor or outdoor trim to fit your plant layout requirements. Designs up to 1200°F process air outlet temperature (call factory for higher temperature requests) are standard for this indirect air heating system.
