In modern industrial and commercial heating systems, gas boosters play a critical role in maintaining consistent gas pressure for industrial burners, industrial boilers and CHP units.

Where supply pressure from the mains or storage is insufficient to achieve optimum combustion, a gas booster ensures the correct flow and stability required for efficient, clean and safe operation.

Dunphy gas boosters are designed and manufactured to the highest standards, combining robust engineering with precision performance. Each unit is factory-tested and fully compliant with the latest BS EN standards.

By maintaining stable inlet pressure, gas boosters optimise combustion efficiency, reduce fuel waste and support the reliable operation of burners across a wide range of gas types, including natural gas, biogas and hydrogen blends.

Compact design and simple installation

Gas boosters are compact, quiet and easy to install, whether as part of a new system or a retrofit solution. Each assembly typically includes a gas-tight enclosure, drive motor, fan impeller, inlet filter and vibration isolation mounts.

The self-contained design simplifies integration within packaged plant rooms and packaged systems, reducing both installation time and on-site engineering requirements.

Factory pre-testing ensures that all performance parameters – from pressure stability to noise levels – meet specification before dispatch. This quality-assured process guarantees reliable, immediate operation on delivery, with minimal commissioning required.

Maintenance and servicing for lasting reliability

Regular maintenance is essential to keep gas boosters operating efficiently and safely. Over time, components such as bearings, filters and seals may experience wear from continuous service, particularly in high-demand environments.

Dunphy recommends routine inspection intervals based on operational hours, with particular attention to impeller alignment, motor condition and pressure performance verification.

Scheduled maintenance not only prevents unexpected downtime but also extends equipment lifespan and ensures compliance with safety and emissions regulations. Dunphy’s service engineers provide full support, offering on-site servicing, genuine replacement parts and vibration testing to detect early signs of mechanical imbalance.

In addition, modern monitoring options can provide early warning of pressure fluctuations or drive anomalies, allowing maintenance teams to address potential issues before they affect system performance.

Efficiency, safety and sustainability

With rising emphasis on energy efficiency and reduced carbon emissions, maintaining optimum gas pressure is more important than ever. A correctly specified and maintained gas booster supports precise combustion control, enabling lower fuel consumption and cleaner operation.

When paired with Dunphy’s low-NOx burners and digital combustion management systems, gas boosters form part of a fully integrated, energy-efficient solution suitable for the most demanding industrial and commercial applications.

Conclusion

Gas boosters are a vital link in the performance chain of any combustion system. By ensuring consistent gas pressure, they help deliver the efficiency, safety and reliability required in modern energy systems.

Supported by Dunphy’s expert engineering and service teams, every gas booster installation represents a long-term investment in operational stability and environmental performance.
