The McDonnell & Miller model 61 is a reliable mechanical low water cut-off for boilers. Designed to enhance system safety and efficiency, it effectively monitors water levels, shutting down the boiler when water levels drop too low. This preventative measure safeguards against boiler damage due to low water conditions.
This unit is equipped with dual precision switches for reliable operation, ensuring that both low water cut-off and alarm or electric water feeder systems are controlled efficiently. The inclusion of packless bellows contributes to the unit's durability and maintenance-free operation.
