The most common cause of overheating and failure of boiler tubes is when hard scale forms on the boiler tube surfaces. This scale comes from calcium and magnesium in the water. But overheating and eventual failure of the boiler tubes isn’t the only side effect. Efficiency is also decreased in the short-term because of the scale's insulating effect on the heat transfer surfaces. A layer of scale just 1/8 inch thick can cause as much as 20-25% loss in efficiency - heat lost right up the boiler stack.
Miura's new MW regeneration process is designed to deliver a more consistent, highly softened water supply, with the added reliability of double tank alternation, our system integrated Colormetry hardness detector, and a control panel that interfaces with Miura's MOM and ER dashboard systems. Miura Water Softener and Hardness Detection can keep your boiler running smoothly and efficiently.
