Hydrolevel 700 Low Water Cut-Off
The Hydrolevel 700 Low Water Cut-Off (45-700) is a contractor-grade 24Vac LWCO designed specifically for hot water boilers and as a secondary safety limit on steam systems. Built with a heavy-duty electromechanical design, this unit eliminates the common failures associated with float-style devices by using the boiler water itself as a conductor. The Hydrolevel 45-700 features a factory-integrated manual reset mechanism that activates after a 30-second low water condition, ensuring the burner circuit remains locked out until a technician can verify system integrity. This specific model includes the EL1214 sensing probe, engineered for standard NPT tappings, and provides immediate power interruption to prevent dry firing damage. Its SPDT switch contacts are rated for 50 VA at 24V, offering robust switching capacity for standard burner circuits without nuisance tripping during temporary power outages.
Key Benefits for Contractors:- Maintenance-Free Reliability: The probe-style design has no moving parts to scale or hang up, unlike traditional float-style cut-offs.
- Lock-Out Safety: The 30-second delay prevents rapid cycling while the manual reset ensures the system stays off until inspected.
- Versatile Compatibility: Rated for up to 160 PSI, making it suitable for high-pressure residential and light commercial hot water boiler protection.
- Direct Probe Sensing: Utilizes the EL1214 probe for precise detection, allowing for flexible mounting in either the boiler shell or riser.
Can this be used on steam boilers?
Yes, the Hydrolevel 700 is frequently installed as a secondary or redundant low water cut-off on steam boilers to provide an additional layer of protection alongside the primary control.
Does the unit reset after a power failure?
The Hydrolevel 45-700 is designed so that a loss of power will not trip the manual reset lockout. Normal operation resumes once power is restored, provided water is still contacting the probe.
What is the maximum pressure rating?
This low water cut-off is engineered to withstand system pressures up to 160 PSI and ambient temperatures up to 250°F.
