R Series burners come in various control configurations. These include modulating operation using an electronic cam for closer and more repeatable control of the air-fuel ratio, as well as options for variable speed drive of the combustion air fan motor to reduce energy consumption and noise levels. The company says integration of O2 trim control ensures the highest achievable combustion efficiency is maintained throughout the modulation range.

Ease of installation, commissioning and servicing are all inherent in the design, with easy access to internal components offered by the hinged access to the burner head.
