Hydrolevel 45-450 450 15-Sec Time Delay On Burner Break 120Vac Oil Steam Boilers

Hydrolevel electronic low water cut-offs utilize a probe installed in the boiler shell or external manifold connected to a control unit, using water as a conductor to complete the circuit between the probe and boiler shell for reliable water level monitoring. When water contacts the probe the circuit completes, but when water drops below the probe level the circuit opens and contacts de-energize the burner to prevent dangerous low water conditions. The system features reliable electronic operation with no moving parts to wear or stick, easy installation, low maintenance without required blowdowns, built-in time delay to prevent burner short cycling, and cost-effective ownership with dependable protection for steam and hot water boiler applications.
