Hydrolevel 450A Low Water Cut-Off
Professional contractors who need high-performance boiler safety solutions trust the Hydrolevel 450A Low Water Cut-Off as their primary defense against dry firing. This 120V steam boiler LWCO is a non-cycling, electronic control specifically engineered for residential and light commercial steam systems. It features the Hydrolevel EL1220 sensing probe, which utilizes the boiler water’s own conductivity to complete the circuit, ensuring there are no mechanical floats to hang up or fail in harsh, scaling environments. For maximum system stability, the Safgard 450 (Part 45-454) incorporates a 15-second burner-off delay to prevent nuisance tripping caused by surging or priming. Once the water level is restored, a 30-second burner-on delay allows for a safe re-fire, providing ample time for an automatic water feeder to stabilize the level. This solid-state primary low water cut-off is easy to install via a 3/4" NPT tapping and includes an automatic reset function to keep the heating system operational without manual intervention.
Key Benefits for Technicians- Electronic Probe Sensing: Eliminates the maintenance-heavy moving parts found in traditional float-style controls, reducing service call-backs.
- Internal Time Delays: The 15-second delay ignores momentary water level fluctuations, protecting the burner from short-cycling.
- Heavy-Duty Switching: Equipped with SPDT relay contacts rated for 5.8 FLA at 120VAC, making it compatible with most standard burner circuits.
- Diagnostic Indicators: Integrated LED lights provide immediate visual status of low water conditions for faster troubleshooting.
- Direct Mounting: Threads directly into the boiler shell, simplifying the piping process and eliminating the need for complex manifolds.
Can the Hydrolevel 450A be used with an automatic water feeder?
Yes, this model is specifically designed for use with automatic feeders like the Hydrolevel VXT-120. Its 30-second on-time delay ensures the feeder has sufficient time to raise the water level above the probe before the burner is energized.
Does this unit require regular blowdowns?
Because the 450A uses a probe rather than a float, it does not require a blowdown valve or daily blowdowns to clear sediment, though annual probe inspection and cleaning are recommended for optimal performance.
How do I prevent the probe from being insulated by Teflon tape?
When installing the EL1220 probe, avoid excessive use of thread sealant or Teflon tape. The probe requires a metal-to-metal ground through the boiler threads to accurately detect the water level.
