AERCO Low Water Cut-Offs are safety devices that interrupt burner fuel or issue an alarm when boiler water level falls below a safe threshold. Available designs include mechanical float assemblies and electronic/probe types, each with dry contacts for interlock to burner controls and indicators for trip status. Key characteristics include trip points, manual or automatic reset options, test capability and mounting orientation. These devices protect boilers from low-water conditions and are installed as part of the burner safety chain with routine functional testing and maintenance to mitigate fouling or scale interference.
