Maintain precise water level management in your commercial hydronic systems with the 164400 combination low water cut-off and pump control. Engineered as part of the 193-7B series, this essential safety component integrates an adjustable potentiometer to provide reliable monitoring and automatic pump activation, preventing boiler damage due to low water conditions.
This control operates by utilizing a probe-based sensing mechanism that communicates with the integrated potentiometer to accurately track water levels. When water drops below the designated threshold, the unit signals the pump to replenish the system, providing a fail-safe measure against dry firing and ensuring the long-term integrity of the heat exchanger.
Key System Performance Baselines:
- Precision Control: Integrated potentiometer allows for fine-tuned sensitivity adjustments based on specific boiler application requirements.
- Safety Assurance: Dual-functionality provides both critical low water cutoff protection and automated boiler feed pump staging.
- Rugged Construction: Built to withstand the thermal stresses of demanding commercial hydronic environments.
⚠️ Application Profile: Designed for use in commercial steam and hot water boiler systems requiring automated make-up water control and low water safety shutdowns.
