The Safgard 24 and 170 Series are heavy-duty electronic low water cut-off (LWCO) controls from Hydrolevel designed to protect boilers by shutting down the burner during low-water conditions. Using a probe and the boiler water as a conductor, these controls automatically reset once safe water levels return and offer optional alarm contacts for added safety.
The 170 Series operates on 120V and is rated for higher pressures up to 160 PSI, while the compact 24 Series typically operates on 24V and is ideal for tight installations. Both series provide reliable, low-maintenance protection for residential and commercial boiler applications.
