Features & Advantages

Designed for optimal economy and reliability.
High thermal efficiency:
- 86 ± 1% on Gross Calorific Value (GCV) of fuel oil.
- 93 ± 1% on Net Calorific Value (NCV) of fuel oil.
Low stack temperature (below 200°C) ensures minimal heat loss.
Up to 80% energy savings compared to electrical heating systems.
Constructed with concentric cylinders, ensuring air and combustion gases do not mix.
High corrosion resistance, long operating life, and minimal pressure drop.
Proven performance across a wide range of process industries.

Direct Air Heating Systems

In Direct Fired Hot Air Generators, the hot combustion gases from a combustion chamber are directly mixed with controlled ambient air and delivered to the spray dryer or process system. This design ensures maximum heat transfer efficiency and compact operation.

Key Benefits

01. Highest possible thermal efficiency through direct heat exchange.
02. Compact, low-maintenance design suitable for continuous operation.
03. Compatible with multiple fuel options — gas, oil, or dual-fuel systems.
04. Ideal for high-temperature processes demanding rapid heat supply.
