Maintain consistent boiler operation with the McDonnell & Miller 126800, a precision-engineered Model 25-A make-up water feeder. This essential component automatically replenishes water levels in low-pressure steam boilers, preventing dry-firing and ensuring safe, long-term system performance.
The feeder utilizes a mechanical float-actuated valve mechanism that monitors boiler water levels in real-time. As the water level drops, the float sinks, opening the feed valve to allow municipal water into the system until the required operating level is restored, automatically shutting off once the optimal set point is reached.
Key System Performance Baselines:
- Automated Regulation: Provides precise, gravity-fed water level control to prevent critical low-water conditions.
- Rugged Construction: Built with durable materials designed to withstand the thermal stressors of steam heating environments.
- Operational Reliability: Minimizes manual maintenance by ensuring consistent water replenishment in residential and light commercial steam boilers.
⚠️ Application Profile: Ideal for replacement or new installation on residential steam heating boilers and small-scale commercial hydronic systems requiring automatic water make-up regulation.
