The gas hot air furnace provides a direct hot air heat source for industrial processes requiring fast temperature rise and stable heat output.
The product can be configured for stable hot-air supply and reduced manual heating work when airflow, temperature, pressure and burner configuration are matched to the production line.
Non-standard customization can be supported for machinery size, duct arrangement, pressure, target temperature, air volume and installation layout.
The product is positioned for machinery, construction, aviation, electronics, pharmaceutical, coating, drying and curing applications.
The supplied introduction lists easy installation, material quality, hardness, resistance to deformation and high-temperature durability. Final material grade, thickness, design temperature and service conditions require written confirmation.
YQF-15, YQF-25 and YQF-35 reference models cover 80,000-350,000 kcal heating capacity and can match 8-35 ton batch circulation grain dryers.
The detailed configuration can include control switches, air pressure controller, electrical components, flame observation port, burner fan, burner nozzle, gas control valve group, burner controller and fault alarm light.
Custom configuration
Gas hot air furnace projects can be customized around high-pressure hot air demand, 300 C reference temperature use, drying room or oven layout, duct route and required air volume.
Please send air volume, target air temperature, pressure requirement, oven or drying room dimensions, duct layout, fuel type, installation space and whether non-standard customization is needed.
Ordering information
For custom heating equipment, commercial terms and document scope are confirmed after the technical configuration, quantity and destination requirements are reviewed.
Buyer FAQ
Gas Hot Air Furnace is used for Machinery, Construction, Aviation, Electronics. Final selection should be based on the working medium, target temperature, capacity and installation conditions.
Gas hot air furnace projects can be customized around high-pressure hot air demand, 300 C reference temperature use, drying room or oven layout, duct route and required air volume.
Please send air volume, target air temperature, pressure requirement, oven or drying room dimensions, duct layout, fuel type, installation space and whether non-standard customization is needed.
MOQ and production lead time depend on the selected power, material, control system, dimensions, quantity and order-specific engineering work. Ask Yigao to confirm both items in the written quotation after the technical configuration is agreed.
Certification and test-document availability varies by model, components and destination market. State the required standard and destination country during inquiry, then ask Yigao to list the applicable documents in the quotation. Do not assume one certificate covers every custom configuration.
Yigao provides technical consultation and equipment coordination. The exact warranty, commissioning, spare-parts, remote-support and on-site service scope should be confirmed in the written quotation or contract for the selected configuration and destination.
