Hydrolevel CG450 Series Cyclegard Low Water Cut-Off is used as the primary low water cut-off on residential and light commercial steam heating boilers. They are also used in certain low pressure steam process applications.

Hydrolevel control utilize a non-moving, heavy duty, electronic probe to sense liquid levels. The probe can be installed in an equalizing line or directly into a boiler or tank. When water is in contact with the probe, it completes a circuit between the stainless steel probe tip and the tank or boiler surface in which the probe is installed. When the water level drops below the probe, the circuit opens. 

Hydrolevel low water cut-offs for hydronic or steam systems use the water signal to allow the burner to operate. If the water level drops below the probe, the circuit opens and the control shuts off the burner. Hydrolevel controls for steam boilers utilize both on-time and off-time delays to prevent boiler short cycling and to facilitate proper boiler automatic water feeding.

To provide added protection for today's small, more efficient steam boilers, the CycleGard low water cut-off is equipped with an Intermittent Level Test (ILT) feature. This important feature adds an extra level of protection against false signals that can be caused by foam and volatile water conditions inside the boiler. The ILT removes power to the burner at preset intervals. During the test, foam dissipates and the water level stabilizes - allowing the Cycle

Gard to monitor the true water level in the boiler, assuring safe and accurate operation.
