ALKALINE (ALK) ELECTROLYZERS
Our (ALK) alkaline electrolyzer is a new type of alkaline electrolyzed water hydrogen production equipment, which has the characteristics of modularization, expandable system design and long service life. This equipment can produce 2,230 Nm³/h Hydrogen at a pressure of 30 bar(g) with a power consumption of 4.7 kWh/Nm³. Maximum hydrogen production capacity: 19400Nm3 /h. It is often used in different fields such as steel mills, oil refineries, chemicals, motor vehicles or energy as a lowcost and reliable green hydrogen production option.
