The Haws 9400LPS AXION® Low Pressure Steam Water Heater replaces hot water tanks when pressurized steam is available. When an emergency shower or eyewash is activated, the flow of water opens a steam control valve. The steam enters a brazed plate heat exchanger, instantly heating the water. This mixing valve blends hot and cold water to produce an output of 80° F (27° C) tepid water. Additional valves keep the system preheated, freeze protected and scald protected. The steam valve will remain closed should there be a loss of water pressure. This station complies with the ANSI Z358.1 standard and mixing valve is designed to meet ASSE 1071For important installation information, please read Scald Warning.Prop 65 Warning.
