IAHR Series

IAHR heaters feature hot side recirculation to provide clean, uncontaminated process air in thermal efficiencies to 90%.

Utilizing the same shell and tube heat exchanger as the IAH heater, the IAHR takes advantage of recirculated hot side air to provide very high thermal efficiency in a very compact size.

High Efficiency o Recirculating Indirect Fired Air Heater
Stelter & Brinck, Ltd. hot side recirculating indirect fired air heater features high thermal efficiency (up to 90%) and lower operating costs than our NR units. Our recirculating model is best suited for higher flow, higher temperature, long production hours or other applications where fuel efficiency is of primary concern.

Contact the factory for assistance in selecting your next system.

• Heavy, insulated double wall construction
• Exhaust
• Outdoor units include burner and valve train weather enclosure
• Prewired to control enclosure for interconnection to customer's DCS, or remote operator station
