Advantages

Product Advantages – Fresh Air Roof Heat Recovery Gas Heating Unit (AirTS-GFT)

1. Integrated Heating & Fresh Air Solution
Combines space heating and fresh air supply in one rooftop unit. It introduces outdoor fresh air while efficiently meeting the heating demands of large and high spaces (4–30m), improving indoor air quality and comfort simultaneously.

2. High Thermal Efficiency
Adopts direct natural gas combustion in the gas coil to heat air directly, reducing intermediate heat loss and achieving high heat exchange efficiency. Fast temperature rise ensures rapid warming even in cold environments.

3. Energy Saving Operation
Stepless heating capacity regulation and variable frequency control allow precise output adjustment based on real-time demand, reducing unnecessary energy consumption and optimizing gas usage.

4. Instant Start & Rapid Response
Instant-on operation enables quick system start-up without long preheating time, ensuring immediate heat supply when needed.

5. Heat Recovery Design
Built-in heat recovery structure maximizes energy utilization by reclaiming exhaust heat, improving overall system efficiency and lowering operating costs.

6. Rooftop Installation – Space Saving
Installed on the roof to save valuable indoor space. Easy installation and simplified duct connection make it suitable for factories, warehouses, gymnasiums, logistics centers, exhibition halls, and other large-span buildings.

7. Anti-Freeze Protection
Equipped with anti-freeze protection to ensure stable operation in low-temperature climates and prevent system damage.

8. Environmental & Clean Combustion
Natural gas as the heat source ensures sufficient combustion, lower emissions, and environmentally friendly performance that complies with modern energy standards.

9. Intelligent & Flexible Control
Supports wireless control, automatic monitoring, and variable frequency operation. Real-time system monitoring improves operational safety and reduces maintenance workload.

10. Multiple Safety Protections
Designed with multiple security protection systems to ensure safe and reliable operation, including combustion protection, temperature protection, and system fault alarms.

Working Principle

Natural gas mixed with air burned through burner, and the heat passes through heat exchanger.

The axial fan provides power to top side, make the return air take away the heat through heat exchager.

After two pressure boosts and silencers, hot air sent to the heating area in the floor.

Technical Comparison

System configuration of gas heating unit

1. Energy source: natural gas, electricity

2. Civil engineering requirements: none

3. Personnel requirements: unattended system

4. System configuration: gas heating unit

System configuration of traditional heating unit

1. Energy source: water, electricity, natural gas

2. Civil engineering requirements: boiler room or heat exchange station

3. Personnel requirements: furnace worker, maintenance worker

4. System configuration: gas boiler or thermal power plant, circulating water pump, primary and secondary circulating water network, heat exchanger, boiler room or heat exchange station, water tank, etc.

The gas heating system as follows

A. Low initial investment - 20% lower initial investment compared to traditional methods

B. Low running costs - direct heating, waterless system saves 40% of operating costs

C. Low maintenance costs - simple system and low failure rate

The water heating system as follows

A. High initial investment - complex system and many equipment

B. High running costs - 30~40% of non-heating ineffective losses

C. High maintenance costs - more equipment, more failure points, high failure rate

Advantage of Heat Recovery Gas Heating Unit

1. Thermal conversion efficiency is above 96%.

2. Deliver heat directly and possess the capability to recover heat from the top of the space, thereby reducing temperature gradients in the space.

3. Stepless regulation of heating capacity (automatically adjust gas flow according to temperature requirement) and accurate temperature control.

4. To meet the heating requirements of the same project, the quantity of equipment is half compared with gas radiation unit.

5. The air volume is accurately proportioned according to the gas flow (one-thousandth fine adjustment) to ensure full combustion and environmentally friendly emissions.
