The Eclipse RatioStar is a modular duct burner designed with on-ratio control for direct fired air heating applications. Burners are configured in rows of up to 24 modules. Propagation modules connect individual burner rows to provide cross ignition. This modular design allows for a wide range of burner matrix configurations. Burner modules are built with high quality stainless steel. Eclipse engineers can design a complete RatioStar duct system with gas train to meet specific customer requirements.
