This robust unit is engineered to provide precise, reliable monitoring of water levels in commercial and industrial heating applications, helping to prevent dry firing and system damage. By integrating the \u003cb\u003e150S-MD\u003c\/b\u003e into your hydronic setup, you gain a dependable safeguard for high-pressure environments that demand strict water management.\u003c\/p\u003e\u003cp\u003eThis level control functions through a float-actuated mechanism that responds dynamically to changes in boiler water surface levels. As the float moves, it mechanically operates the internal switches to signal the boiler feed pump or low water cut-off circuit, ensuring that the water level remains within the pre-set safety parameters. Its rugged construction is designed specifically for the demanding pressures found in heavy-duty steam heating systems.\u003c\/p\u003e\u003ch4\u003eKey System Performance Baselines:\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cb\u003eAutomatic Regulation:\u003c\/b\u003e Provides continuous and responsive water level monitoring for steam boilers.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eDurability Standard:\u003c\/b\u003e Constructed with industrial-grade materials to withstand high-pressure operating cycles.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eSafety Integration:\u003c\/b\u003e Functions seamlessly with pump control and low-water cut-off circuits to prevent system failure.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eOperational Reliability:\u003c\/b\u003e Designed for longevity in intensive mechanical room environments.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e⚠️ \u003cstrong\u003eApplication Profile:\u003c\/strong\u003e Primarily utilized in commercial steam boiler installations, high-pressure hydronic systems, and industrial processing steam plants requiring precise, float-operated level management.\u003c\/p\u003e","brand":"McDonnell \u0026 Miller","offers":[{"title":"Default Title","offer_id":43125908111454,"sku":"171802","price":1098.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0663\/7151\/8558\/files\/171802_image_ef3495e8-ce66-4667-8cbf-1569c4048d5c.png?v=1786044667","url":"https:\/\/nationalboilersupply.com\/products\/mcdonnell-miller-171802-150s-md-high-pressure-level-control","provider":"National Boiler Supply","version":"1.0","type":"link"}
