Engineered for demanding industrial and commercial environments, this versatile unit provides reliable low water cut-off protection and manages feedwater pump operation to ensure system efficiency and safety.\u003c\/p\u003e\u003cp\u003eThe 94M series utilizes a proven float-actuated mechanism that responds precisely to water level fluctuations within the boiler. As the water level drops below the established set point, the control triggers the pump to replenish the system while simultaneously providing secondary low-water cutoff protection, effectively preventing dry firing and potential thermal damage to the heat exchanger.\u003c\/p\u003e\u003ch4\u003eKey System Performance Baselines:\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrecision Control:\u003c\/strong\u003e High-pressure rating designed specifically for demanding hydronic and steam boiler applications.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDual Functionality:\u003c\/strong\u003e Integrated pump control and low-water cut-off features in a single, streamlined chassis.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOperational Reliability:\u003c\/strong\u003e Rugged design capable of withstanding constant thermal cycling in high-demand environments.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e⚠️ \u003cstrong\u003eApplication Profile:\u003c\/strong\u003e This controller is designed for high-pressure commercial and industrial steam boiler installations where consistent water level management and safety shutdown are critical to preventing catastrophic equipment failure.\u003c\/p\u003e","brand":"McDonnell \u0026 Miller","offers":[{"title":"Default Title","offer_id":43125879668830,"sku":"165900","price":2117.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0663\/7151\/8558\/files\/165900_image_7b5288ac-e86b-4403-b252-dc6e98990333.png?v=1786042741","url":"https:\/\/nationalboilersupply.com\/products\/mcdonnell-miller-165900-94m-high-pressure-combination-level-control","provider":"National Boiler Supply","version":"1.0","type":"link"}
