Protect your steam boiler from dry-firing and maintain optimal water levels with the McDonnell & Miller 132800 Series 47-2. This integrated unit serves as a primary low-water cut-off and automatic water feeder, providing essential safety and operational reliability for residential and light commercial steam heating systems. By automatically replenishing water when levels drop, it prevents critical damage to the heat exchanger and ensures continuous, efficient system performance.
The unit functions through a float-operated mechanism that detects changes in water surface level. When the water level reaches the designated low point, the mechanical feeder valve initiates an automatic replenishment cycle. Simultaneously, the integrated switch provides a positive electrical shut-off to the burner circuit if water levels fall below the critical threshold, adding a secondary layer of protection against dry-firing.
Key System Performance Baselines:
- Automatic Regulation: Ensures consistent water level maintenance to prevent boiler dry-firing.
- Safety Integration: Features a built-in low water cut-off switch for rapid burner power termination.
- Reliable Construction: Engineered for durability in demanding high-temperature steam environments.
⚠️ Application Profile: Designed for use on steam heating boilers with low-pressure applications. Ideal for residential or light commercial installations requiring automated water management and integrated dry-fire protection.
