indirect fuel oil heater air duct
When connecting an indirect fuel oil heater to your workspace, the air duct is a critical component that determines overall system performance and safety. Our Indirect Fuel Oil Heater Air Duct is specifically crafted to meet this challenge. It efficiently channels clean, hot air from your heater's output over considerable distances, ensuring targeted warmth without compromising the duct's integrity. The core challenge in such applications is heat resistance coupled with physical durability—our duct excels in both. The innovative three-layer design, with a reinforced insulation core, maintains air temperature, improves fuel efficiency of your heater, and protects the outer layer from degrading under high thermal stress. This translates to a longer-lasting duct, reduced replacement costs, and a more effective heating solution for your job site or facility.

Product Advantages
- Extreme Temperature Resilience:
- Feature: Standard operating range of -45°C to 300°C. Optional ultra-high-temp grade available for applications up to 1200°C.
- Benefit: Guarantees safe, reliable performance at the full operating output of your indirect fuel oil heater without melting, cracking, or emitting harmful fumes.
- Robust Multi-Layer Construction:
- Feature: Built with three distinct material layers: an inner smooth surface for optimal airflow, a middle insulating layer for heat retention, and a tough external jacket with embedded steel wire helix.
- Benefit: Provides excellent thermal insulation (reducing heat loss), structural stability, and unparalleled protection against punctures, tears, and compression.
- Superior Abrasion & Drag Resistance:
- Feature: Externally reinforced with a galvanized or powder-coated steel wire spiral. The tough outer material is resistant to oils, acids, and alkalis.
- Benefit: Allows the duct to be dragged across rough concrete, gravel, or construction debris without wear. Perfect for dynamic job sites where equipment is frequently repositioned.
- Safety & Durability Certified:
- Feature: Engineered to be flame-retardant, waterproof, and chemically resistant.
- Benefit: Enhances job site safety by reducing fire risk and ensures longevity when exposed to harsh elements or industrial chemicals like exhaust fumes.
- Flexibility & Customization:
- Feature: Highly flexible despite its strength, allowing for easy routing around obstacles. Available in a range of diameters (80mm to 1000mm) and standard lengths (3.6m or 7.6m). Colors: Gray, Yellow, Black, Blue (custom colors for large orders).
- Benefit: Offers a perfect fit for any heater model and application layout. High-visibility colors (Yellow) improve safety by marking hot air pathways.
Application Scenario
- Primary Use: Temporary Spot Heating with Fuel Oil Heaters. Directly connect to the hot air outlet of your portable indirect-fired fuel oil or gas heater to distribute heat to specific areas in warehouses, agricultural buildings, construction sites, or during building renovation.
- Ground Thawing & Concrete Curing: Snake the duct under tarps or into enclosed spaces to deliver heat directly to frozen ground or to maintain temperature for concrete setting in cold weather.
- Industrial Process Heat & Ventilation: Used with industrial dryers (e.g., plastic pellet dryers), printing machinery, and for general hot air conveyance in manufacturing.
- Exhaust & Fume Extraction: Suitable for removing hot exhaust gases, steam, and non-corrosive fumes from engines, generators, and chemical processes. The abrasion-resistant design also handles light particulate matter like dust and fibers.
- Military, Aviation, & Specialized Construction: Provides reliable air transfer for heating, ventilation, and exhaust in demanding field environments and specialized facilities.
Frequently Asked Questions
1
Is this duct specifically compatible with my indirect fuel oil heater?
Yes. This duct is engineered as a universal accessory for indirect-fired air heaters (both fuel oil and gas types). Ensure you select the correct inner diameter to match your heater's outlet port for a secure, efficient connection, typically using standard hose clamps.
2
What length and diameter should I choose?
For most temporary heating applications, the 7.6m length provides greater reach. Diameter is critical: measure your heater's outlet nozzle. Common sizes are 200mm, 250mm, and 300mm. Choosing a duct that is too small will restrict airflow and overload your heater.
3
Can it handle the full temperature of my heater's output?
Absolutely. The standard grade (-45°C to 300°C) exceeds the output temperature of most commercial indirect fuel oil heaters. If your heater operates at exceptionally high temperatures or for exhaust applications, select our optional 1200°C grade.
4
Is it safe to drag the duct across rough ground?
Yes. The external steel wire helix and wear-resistant outer layer are designed specifically for this purpose, protecting the duct from damage during site moves.
5
What is the insulation value? Can I use it outdoors?
The middle layer provides significant thermal insulation, minimizing heat loss during transfer. The duct is waterproof and weather-resistant, making it suitable for outdoor use. For very long runs or extreme cold, adding external insulation wrap is recommended for maximum efficiency.
