The SAACKE HD60D2 is part of the HD series of duoblock burners, designed for medium to high capacity industrial combustion applications. These burners are known for their robust construction, reliability, and flexibility in handling various fuels, including natural gas, light oil, heavy oil, or dual-fuel operation. The duoblock design separates the burner head from the combustion air fan, allowing for optimized placement and integration into various boiler fronts or process heating systems. The HD series aims for efficient combustion with potentially low emissions, depending on the specific configuration and application requirements.
