The SPEC COM burner from Preferred is a versatile, high-performance solution built for demanding industrial applications, including field-erected boilers, heaters, and thermal oxidizers. Its rugged design ensures long-term reliability in extreme environments, making it ideal for operations in varying climates.
A key feature is its ability to handle a broad range of fuels, from traditional options like natural gas and propane to alternatives such as hydrogen and low-BTU gases. This fuel flexibility makes it especially useful for industries exploring renewable energy sources.
Designed for low NOx emissions, the SPEC COM can achieve levels as low as 20 ppm with Flue Gas Recirculation (FGR), meeting strict environmental standards without sacrificing efficiency. With no moving parts in its core design, it minimizes maintenance and maximizes operational uptime, supported by Preferred's expert customer service.
This burner is an ideal choice for both new installations and retrofits, delivering reliable, efficient combustion with low emissions.
Made in the USA: Preferred's SPEC COM burners are engineered and fabricated in the USA, supporting local industry, and boosting the economy.
Low NOx Emissions: Capable of achieving NOx levels as low as 22 ppm or less with FGR, meeting stringent environmental standards without requiring additional emissions treatment equipment.
