Clean heat matters in sanitary processing.
In spray drying and thermal processing systems, the quality of the heated air directly impacts product quality, efficiency, and operational reliability.
That is why the Dahmes Patented Indirect Heater is engineered differently.
Built around a patented center-fire radial design, the system keeps combustion air completely isolated from the process stream while maximizing heat transfer efficiency. The result is ultra-clean, stable, high-temperature air ideal for spray dryers, fluid beds, and other sanitary thermal applications.
Key advantages include:
✔ Up to 96% thermal efficiency
✔ NOx-free process air
✔ Reduced energy loss through combustion heat recirculation
✔ Stable, predictable thermal performance
✔ Hygienic design built for sanitary production environments
Unlike direct-fired systems, the Dahmes Indirect Heater eliminates the risk of combustion byproducts entering the process air stream — helping protect product quality, flavor, color, and compliance standards.
The patented radial tube arrangement and center-fire geometry create an optimized temperature delta that improves heat transfer and captures more usable energy before exhaust.
Beyond performance, the system is designed with practical operation in mind:
• Reliable maintenance access
• Long-term durability
• Cleanability for food-grade environments
• Consistent performance during extended production runs
At Dahmes, we believe thermal systems should deliver more than heat. They should deliver efficiency, cleanliness, reliability, and confidence.
