Clean, efficient, and cost-effective hot air solutions for industrial applications.
High-Efficiency Hot Air Solutions
Hot air is required as a heating medium in several industrial processes for drying operations, heating applications, and even for combustion. Conventional direct-fired hot gas generators using oil/NG/diesel/kerosene as fuel have high OPEX and cause contamination of the product due to the flue gas coming in direct contact with it.
Our indirect heating systems using locally available cheap solid fuels offer the advantage of clean, uncontaminated air for sensitive industries like specialty chemicals (e.g., Precipitated Silica), pharma, food, consumer products, and more at a much lower cost.
Urja-Disha is a unique company having the capability to design CFHAGs offering Hot Air temperature as high as 750°C.
Key Benefits
- Reduced tube corrosion and hence less maintenance
- Longer tube life and equipment availability
- Considerable OPEX savings
- Increased efficiency
- Higher safety
- Ease of operation. Quick start & shut-down
Compact & Efficient Design
For moderate air temperature (up to 350°C), we offer a very compact design with a low footprint and minimal refractory (avoiding frequent shutdowns), with quick start & shutdown, and ease of maintenance.
We have a large number of CFHAGs working efficiently to the satisfaction of our clients, boosting their competitiveness and market shares, and continuously contributing to their bottom lines.
