Our Nexus® family of products are used in boiler applications to not only provide the flame safeguard function, but also control the entire burner operation in a manner which greatly improves efficiency and lowers operational costs. Optional variable speed drive (VFD) support and Oxygen trim provide power savings and reduced greenhouse gas.
