McDonnell & Miller Boiler Controls
What are Low Water Cut-Offs used for?
McDonnell & Miller Low Water Cut-offs are specially designed to protect steam boilers from the hazards of a low water condition. In operation they will interrupt the electrical current to the firing device, if the water in the system drops below the boiler manufacturers’ minimum safe water level.
Low water cut-offs also provide an additional circuit for a water feeder or a low water alarm, should you desire to install one, for additional protection.
What are Water Feeders used for?
McDonnell & Miller Boiler Water Feeders and Feeder Cut-Off Combinations are used to provide automatic operation, and to safeguard steam and hot water boilers against the hazards of a low water condition. A feeder cut-off combination mechanically adds water as needed to maintain the required minimum water level, and electrically stops the firing device in case of an emergency.
