High Efficiency Hot Air Source for Process Air Recirculating Indirect Fired Air Heater
High temperature indirect heater for spray dryers, fluid bed dryers, chemical dryers, drying ovens, pharma, dairy, food High Temperature, High Thermal Efficiency Recirculating Indirect-Fired Air Heater

Recirculating indirect air heaters feature hot combustion air side recirculation to provide clean (free from the by-products of combustion) hot air in thermal efficiencies up to 90%.

With high thermal efficiencies, Stelter & Brinck's hot side recirculating process air heater provides lower fuel and operating costs than our non-recirculating units. Our recirculating indirect model is best suited for higher flow, higher temperature, long production hours or other applications where fuel efficiency is of primary concern. (Designs up to 1200°F process air outlet temperature are standard- call factory for higher temperature requests.)

Stelter & Brinck's IAH-R-USDA unit has been certified as being USDA compliant equipment for the dairy industry.
