Laars Heating Systems R0021901 Low Water Cut Out 320735-701 mechanical fit on compatible compressorThe Laars Heating Systems R0021901 Low Water Cut Out is a critical safety component designed for professional hydronic boiler maintenance and equipment protection. This LWCO safety device serves as the primary defense against dry fire conditions by monitoring real time fluid levels within the heat exchanger. When water levels drop below the required threshold, the low water cut out kit immediately interrupts the burner circuit, preventing catastrophic
