From textiles to pharmaceuticals, drying is a critical process step that consumes vast amounts of energy. The challenge lies in generating high temperatures without contaminating the product with combustion gases. Giriraj's Industrial-grade Indirect Hot Air Generator (HAG) is engineered to solve this by providing clean, uniform hot air with reduced energy consumption.
Understanding Indirect Heating Technology
Direct heating often exposes products to smoke and ash. Our Indirect HAGs utilize a sophisticated heat exchanger design to ensure that the air contacting your product is 100% clean.
Heat Exchanger: The core of the system is an MS/SS multi-pass high-efficiency design. This maximizes the surface area for heat transfer, ensuring that the energy from the biomass fuel is effectively transferred to the process air.
Temperature Output: The system can generate clean hot air up to 250°C, making it suitable for high-demand drying applications in packaging, printing, and chemicals.
Performance Specifications
Designed for scalability, the Hot Air Generator offers a capacity range of 1,00,000 – 10,00,000 kcal/hr, customizable based on specific airflow and pressure requirements.
Insulation: We utilize high-grade ceramic wool to insulate the system, preventing ambient heat loss and improving overall safety.
Automation: The unit comes with a Digital or PLC-based control panel, allowing operators to maintain stable temperatures with minimal manual intervention.
Sustainability in Heavy Industry
Industries such as Textiles, Pharmaceuticals, and Paper/Packaging often have high carbon footprints due to thermal energy requirements. By switching to a biomass-fired HAG, these sectors can utilize a renewable, carbon-neutral fuel.
Emission Control: The cleaner combustion of pellets results in significantly lower NOx and SOx emissions compared to conventional fossil fuels.
Maintenance: The system is designed for minimal maintenance, supported by our 24/7 technical support team.
Conclusion
For industries requiring precise, clean drying temperatures, the Giriraj Indirect Hot Air Generator offers a robust solution. It combines the economic benefits of biomass—saving up to 50% against LPG—with the technical precision required for modern manufacturing.
