Protect your commercial steam boiler system against damage with the reliable McDonnell & Miller 93-7B-M. This essential component, identified by part number 163100, serves as a dual-function low water cut-off and pump controller, designed to maintain optimal water levels and prevent burner operation during low-water conditions.
The unit utilizes a heavy-duty float mechanism that reacts precisely to changes in water levels within the boiler vessel. When the water level drops, the switch activates the secondary pump controller circuit to replenish the system, while simultaneously providing a safety cutoff to prevent thermal stress and internal damage to the heat exchanger.
Key System Performance Baselines:
- Precision Switching: Reliable mechanical contact operation for consistent boiler cycling.
- Dual Functionality: Integrated pump control and low-water safety cutoff in one robust assembly.
- Heavy-Duty Construction: Built for the demands of industrial and commercial steam heating applications.
⚠️ Application Profile: Ideal for industrial steam boilers, commercial heating systems, and high-pressure process steam vessels requiring precise water management and integrated safety monitoring.
