High-efficiency, low-emission gas burners for industrial boilers
Reliability and design flexibility with SIABS gas burners for industrial boilers
IABS industrial boiler burners are engineered to deliver high performance, low emissions and long-term reliability.
Our R&D department works closely with each customer to design custom-built burners, produced in short lead times and fully compliant with current European regulations.
Thanks to Premix technology and the use of metal-fibre burners, SIABS gas burners ensure:
- Reduced NOx, CO and CO₂ emissions
- Uniform heat distribution across the burner surface
- Precise flame modulation
- Durability and consistent performance, even in demanding conditions

Premix Gas Burners for Boilers: Performance and Sustainability
SIABS Premix burners are designed to meet the world’s most stringent environmental standards (EU, USA, Canada, Australia, Russia).Operating in Premixmode allows for clean, controlledcombustion, even with minimal airflow, while maintaining a stable and efficient flame.
Advantages of Metal-Fibre Technology in Boiler Burners
SIABS metal-fibre gas burners offer multiple competitive advantages:
- Wide thermal-power modulation range
- Choice of blue flame or red flame, depending on the application
- Flexible design adaptable to cylindrical or flat geometries
- High heat output in compact spaces, optimising boiler volume
- Resistance to thermal shock and temperature fluctuations
Applications of SIABS Boiler Burners
Our high-efficiency gas burners are used across many sectors and systems:
- Industrial and commercial boilers
- Residential boilers
- Water heaters and boilers
- Condensing boilers
- Large HVAC systems
Three Burner Models Available
The SIABS catalogue includes three customisable designs, available in different shapes, diameters, lengths and metal-mesh types:
1. COMPACT
Compact metal-fibre burners ideal for confined spaces. Provide precise modulation and flame stability, suitable for cylindrical or irregular designs.
Power range: 1 to 500 kW
2. FLAT
Flat burners designed for high-temperature applications (red flame). Built with wear-resistant materials and customisable in size and output.
Power range: 10 to 200 kW
3. CYLINDRICAL
High-performance cylindrical burners, available with or without a metal-fibre cap. Deliver maximum thermal efficiency in minimal time, configurable in height and diameter.
Power range: 18 kW to over 1 MW
