Safgard™

Safgard is a line of low water cutoffs from Hydrolevel of North Haven, Connecticut. A Safgard control senses boiler water at a probe and opens the burner circuit when the water falls below a safe level, so the boiler does not fire dry.

BoilerSupplies.com carries the Safgard 24 and 170, 250, 270SV, 400, 500, 600, 711 and 724, and 1100 Series low water cutoffs under the Safgard Controls family. The series number is what separates one model from the next. So a replacement is picked by reading that number off the old control, not by matching the look of the housing. The Safgard Low Water Cut-Off Cross Over is the piping fitting that mounts a control on the boiler.

Do techs call a Safgard control an LWCO, a low water cut-off switch or a probe cutoff?

Yes. Those are the names techs use for a control that cuts the burner when the boiler water falls too low, and a Safgard is one of them. Safgard units sense the water at a probe, which is why they get called probe cutoffs, as against float cutoffs.

What should I copy off the old Safgard control's label?

The series number first, such as 270SV, 400 or 1100. Then the full model line and anything else printed on the label, or simply a clear photo of the whole label. Add the quantity when you send it through BoilerSupplies.com.

What is the Safgard Low Water Cut-Off Cross Over?

It is the piping fitting that mounts a Safgard control on the boiler, listed beside the Safgard low water cutoffs on BoilerSupplies.com. Whether a job needs one depends on the piping already there, so send a photo of how the old control is piped, with its series number, alongside the order.

How is a probe low water cutoff different from a float cutoff?

A float cutoff uses a float in a chamber that drops with the water and trips a switch. A Safgard control has no float: it senses the water at a probe and opens the burner circuit when the water no longer reaches it. Both do the same job in different ways, and a Safgard replacement order starts from the series number on the old label.
